Abstract

PURPOSE:To enable a pump to be operated efficiently with its constitution being simple by having a needle make a reciprocating motion through a derivative body magnetized by the permanent magnet of an ignition generator. CONSTITUTION:One end of a derivative body 6 composed of a magnetic material is to be fixed facing each other in a position where it is close to a permanent magnet 1, which is composed of the body of rotation of an ignition generator, and where an extreme minuteness gap ga is maintained between the magnetic pole passing surface. The other end of the derivative body 6 is to face the needle 7 made of a magnetic material through an operating gap gw. The derivative body 6 and the needle 7 are magnetized in this manner each time the magnetic pole of the permanent magnet 1 passes through one end of the derivative body 6 so as to cause the needle 7 to make a reciprocating motion. The reciprocating motion of the needle 7 makes the fluid inflow from an intake opening 15 and outflow from a discharging opening 16, both openings provided on a pump body 4. The pump can thus be driven by utilizing the permanent magnet 1 rotating for ignition purpose.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a pump for a magnetic ignition internal combustion engine, and in particular to a magnetic ignition pump in which the pump is driven using a permanent magnet used for ignition. Concerning pumps for internal combustion engines.

(Prior Art) Magnetically ignited internal combustion engines generally use a generator to obtain ignition energy. In this case, the generator may be a separate dedicated generator, or may be built into a conventional engine generator to provide an output tailored to the ignition characteristics.

This type of device has a power generation coil and an iron core, and in order to excite this iron core,
It has a permanent magnet that rotates together with the flywheel.

In addition, all engines, not just magnetic ignition internal combustion engines, require a pump to circulate fuel, lubricating oil, etc., and a variety of pump drive methods have been proposed and used in this case. It is well known that there are.

(Problems to be Solved by the Invention) In the conventional device described above, the generator for ignition and the pump are completely unrelated. That is, the generator only performs the power generation function, and the pump only performs the pumping function, and they are structurally separate entities.

Therefore, when considering the device as a whole, there are considerable problems in terms of installation area, weight, and cost.

Looking back, it can be seen that the permanent magnet in a magnet-ignition internal combustion engine is not used in any way other than in the rotation section required to excite the iron core for power generation.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a pump for a magnetic ignition internal combustion engine that effectively utilizes each device installed in the internal combustion engine and has a simple configuration and is capable of efficient operation. It is an object.

[Structure of the Invention] (Means for Solving the Problems) The present invention will be described with reference to FIG. 1 corresponding to an embodiment. One end of the inductor 6 made of a magnetic material is fixed and faced to the magnetic pole passing surface at a position that maintains an extremely small air gap, and the other end of the inductor 6 is connected to the mover made of the magnetic material through an operating gap g _w . Each time the magnetic pole of the permanent magnet 1 constituting the rotating body of the generator passes one end of the inductor 6, the inductor 6 and the movable element 7 are magnetized to cause the movable element 7 to perform reciprocating motion. The structure is such that the reciprocating motion of the mover is used for pump operation.

(Operation) Therefore, in the stopped state, there is no electromagnetic induction phenomenon, so the inductor 6 is not magnetized, the mover 7 is pushed upward by the force of the plunger spring, and the pump does not operate.

When the rotating body made of permanent magnets rotates according to the illustrated arrow, the permanent magnets 1 successively pass below the induction body 6. Therefore, each time the permanent magnet 1 passes one end of the inductor 6, the inductor 6 and the mover 7 are magnetized to cause the mover 7 to perform reciprocating motion, and this reciprocating motion can be used to operate the pump.

(Example) Examples will be described below with reference to the drawings.

First, the basic idea of the present invention will be explained using FIG. 4.

In FIG. 4, 1 is a permanent magnet that can be moved in the direction of arrow M in the figure. A case will be considered in which 2 is a dielectric and is placed through a microgap ga, and the movable element 3 is further placed through an operating gap _gW .

Note that N and S in the figure represent the polarities of the magnetic poles, respectively, and indicate how the inductor 2 and the mover 3 are magnetized by the magnetic induction phenomenon of the permanent magnet 1.

In this arrangement, when the permanent magnet 1 is moved according to the arrow, when the N pole of the permanent magnet 1 approaches the inductor 2, the polarity of the inductor 2 becomes S pole on the air gap ga side and S pole on the air gap g _W as shown in the figure. The side becomes the N pole. Similarly, the movable element 3 has an S pole on the side of the gap g _W and an N pole on the opposite side, and the movable element 3 is attracted toward the inductor 2 .

Next, when the N pole of the permanent magnet 1 leaves this state, the magnetic induction disappears. Therefore, the movable member 3 is always connected to the inductor 2 by a spring (not shown).
If a force is applied to separate the magnet from the magnet, the attraction during the magnetic induction phenomenon and the return when the phenomenon disappears are alternately repeated, making it possible to use this operation as a pump.

FIG. 1 is a block diagram of an embodiment of a pump for a magnetic ignition internal combustion engine according to the present invention. In FIG. 1, 1 is a permanent magnet that rotates in the direction of the arrow.

That is, this is the permanent magnet of the magnetic ignition generator. Then, the pump body 4 is attached with a distance between the permanent magnet 1 and the air gap ga. The pump body is
A dielectric 6 made of a magnetic material is provided in the lower part of the casing 5 made of a non-magnetic material, and a working air gap is formed between the dielectric 6 and the dielectric 6 made of a magnetic material.
A mover 7 made of a magnetic material is provided apart from g _W. 8 is a plunger spring, 9 is a suction valve made of non-magnetic material, 10 is a valve seat also made of non-magnetic material, 11 is a discharge valve made of non-magnetic material, 12 is a suction valve spring, 1
3 is a discharge valve spring, and 14 is an O-ring.
R is the radius of rotation of the permanent magnet 1 and the rotating body including the permanent magnet 1, which corresponds to the permanent magnet for power generation in a so-called magnet ignition combustion engine. Note that 15 is a suction port, and 16 is a discharge port.

Next, an overview of the operation will be explained.

First, in the stopped state, since the permanent magnet 1 does not rotate, there is no electromagnetic induction phenomenon with respect to the inductor 6, and therefore the inductor is not magnetized.

Therefore, the mover 7 is connected to the plunger spring 8.
Because it is pushed upward and stopped by
The pump has also stopped working.

Now, when the rotating body including the permanent magnet 1 rotates in the direction of the arrow shown in the figure, the permanent magnets sequentially pass below the induction body 6. In this case, when the magnetic attraction force generated between the inductor 6 and the movable element 7 becomes larger than the plunger spring 8, the movable element 7 moves in the direction of the inductor 6. However, when the movable element 7 is not energized, the interior of the movable element is already filled with liquid via the working air _gW . However, when the mover is energized and moves downward, liquid is sucked into the interior surrounded by the valve seat 10 through the suction valve 9. When the bias is removed, the movable element 7 moves upward. At this time, the liquid in the pump chamber is discharged by opening the discharge valve 11.
As a result, the liquid enters through the suction port 15 and is discharged from the discharge port 16 in accordance with the arrow.

As is clear from the above, according to this embodiment, the pump function can be achieved using the permanent magnet for the generator of the magnet ignition internal combustion engine.

FIG. 2 is a block diagram of another embodiment of the present invention.

In this example, two derivatives 17-1, 17-
2, the pump function is achieved by the suction operation of the cap-shaped movable element 18.

The mover 18 has a diaphragm spring 1 in the center.
The flexible diaphragm 21 is fixed at one end by a diaphragm ring 20 made of a non-magnetic material.

Further, the other end of the diaphragm has a middle body 22 made of a non-magnetic material and a bottom body 2 made of a non-magnetic material.
Clamp at 3. 24 is a suction valve, and 25 is a discharge valve.

Note that, as described in the first embodiment, the permanent magnet 1 rotates and moves as the generator operates.

Next, an overview of the operation will be explained.

When there is no magnetic induction, the mover 18 is moved toward the middle body 22 by the diaphragm spring 19 and comes into contact with the ceiling of the middle body 22, and the inductors 17-1, 1
7-2, an operating gap _gW is formed between it and 7-2.

Now, when the permanent magnet 1 approaches the dielectrics 17-1, 17-2, each of the dielectrics 17-1, 17-2 and the mover 18 are magnetized. When the magnetic attraction force generated between the induction body and the mover overcomes the force of the diaphragm spring 19, the mover 18 moves toward the induction bodies 17-1 and 17-2, and the liquid flows through the suction valve 24. is sucked into the pump chamber.

Furthermore, the permanent magnet 1 has dielectrics 17-1 and 17-2.
When the movable element 18 moves away from the diaphragm spring 19 and the magnetic induction disappears, the movable element 18 moves toward the middle body 22 by the diaphragm spring 19. At this time, the liquid in the pump chamber is discharged via the discharge valve 25.

In this embodiment as well, the pump function can be achieved using a permanent magnet for the generator of the magnet ignition internal combustion engine.

FIG. 3 is a block diagram of still another embodiment.

In this example, the derivatives were separated and 26-1, 26
-2, and these are provided with tongue pieces to be directly magnetized by the permanent magnet 1.

In FIG. 3, the same parts as in FIG. 1 are given the same reference numerals.

Characteristic parts of this embodiment are as follows.

First, the inductor is divided into two parts 26-1 and 26-2, which are attached or welded at the positions shown in the figure, and furthermore, as shown in the right side view of FIG. 3b, a tongue piece 26-2 and a The point is that it extends to a position where it is integrated and directly magnetized by the permanent magnet 1. The other configurations are the same as in FIG. 1.

Next, although the operation is basically the same as that in FIG. 1, an outline will be explained.

First, when there is no magnetic induction, the mover 7 is moved toward the main body by the flange spring 8, and an operating gap g _W is formed between one end of the mover 7 and the inductor 26-2. . When the permanent magnet 1 approaches the inductors 26-1 and 26-2, the tongue piece 26-1
(26-2) and the mover 7 are magnetized, and the mover 7
When the magnetic attraction force generated between the plunger spring 8 and the induction body 26-2 overcomes the plunger spring 8, the movable element 7
moves in the direction of the dielectric 26-2. At this time, liquid is sucked into the pump chamber formed by the mover 7 and the casing. When the permanent magnet 1 separates from the induction body and the magnetic induction disappears, the plunger spring 8 moves the mover 7 toward the main body, and at this time, the liquid in the pump chamber opens the discharge valve 11 and is discharged.

As is clear from the above description, the pump function can also be achieved in this embodiment.

[Effects of the Invention] As explained above, according to the present invention, since the pump is driven using a permanent magnet rotating for ignition in a magnet-ignition internal combustion engine, there is no need to add a special device. Therefore, it is possible to provide a pump for a magnetic ignition internal combustion engine that can be operated efficiently.
