Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a device for replenishing brake oil to a brake system of a motor vehicle.

(Prior art) When air bubbles enter the brake oil or the brake oil becomes dirty, all or part of the brake oil must be replaced. New brake oil in the reservoir tank is pumped from the master cylinder to the brake pipe, and this oil is used to push out the brake oil that contains air bubbles or is dirty from the wheel cylinder at the end of the brake pipe. To perform this work, it is necessary to continuously replenish the reservoir tank with new brake oil.

For this reason, up until now, an automatic replenishment device equipped with an air pump as seen in Japanese Utility Model Application No. 52-34390 has been used, or an so that you can
Measures have been taken to hold a commercially available container vertically directly above the reservoir tank using a holding member equipped with a holding bracket and screws or elastic legs, and replenish brake oil using its own weight; however, in the former case, In addition to requiring special equipment, there is the hassle of having to transfer brake oil from a commercially available container each time. There have been problems in that the metal fittings and holding members do not fit, or the supply container cannot be installed because it hits the bonnet, etc., and it cannot be applied to a device with an inclined injection port.

(Purpose) The present invention was made in view of the above circumstances,
The purpose is to provide a new device that can be easily installed and automatically replenishes brake oil regardless of the shape, position, or inclination of the reservoir tank.

(Structure) That is, in order to achieve this object, the present invention has the following features:
Connect one pipe that connects to the replenishment container and the other pipe that connects to the replenishment port so that the axes of both pipes intersect at an obtuse angle, and attach the pipe on the bottom surface in the middle of the pipe that connects to the replenishment port. A brake oil replenishing device is provided with a removably attached seating member having a support rod along the .

Therefore, details of the present invention will be explained below based on illustrated embodiments.

FIG. 1 shows an embodiment of the present invention, in which a side body 2 of a rotary on-off valve indicated by reference numeral 1 in the figure includes two pipes 3 and 4 whose axes intersect with each other at an obtuse angle. One of the pipes 3 is connected to the replenishment container 10 to form a replenishment pipe that leads the internal brake oil to the on-off valve 1, and its tip is connected to the rim of the container 10. The other pipe 4 is provided with a cap 5 whose tip forms a replenishment nozzle, and a seat 6 extending from one side that abuts the edges of the inlet of the reservoir tank 11 is installed in the middle thereof. . To explain in more detail, the seat 6 is rotatably mounted so that the overhanging side faces the reservoir tank 11 or the opposite side, and is held in these positions by friction or the like. Two or more support rods 7 whose tips are slightly curved outward are vertically installed on the lower peripheral edge of the seat 6, and the seat 6 is separated by these support rods 7.
The inner lower surface 6a and the outer lower surface 6b of the inlet are configured as contact surfaces for the edge of the inlet.

Note that the reference numeral 8 in the figure indicates a rotating handle of the on-off valve 1.

In order to attach the replenishment container 10 to the reservoir tank 11 with the inlet facing upward using the device configured in this way, the seat 6 is rotated so that the support rod 7 is located on the container 10 side, and the pipe The seat 6 is placed on each edge of the inlet of the reservoir tank 11 so that the peripheral wall of the reservoir tank 11 is sandwiched between the seat 4 and the support rod 7. As a result, the replenishment container 10, which is located at the end of the pipe 3 connected at an obtuse angle and is tilted to one side, applies a horizontal component force corresponding to its weight to the tip of the support rod 7, and this part is connected to the reservoir tank 11. In order to press against the peripheral wall, the replenishment device almost holds the replenishment container 10 at three points: the inner lower surface 6a of the seat 6, the root of the pipe 4, and the tip of the support rod 7, as shown in FIG. 2A.
Hold it at an angle of 60°. Therefore, when the on-off valve 8 is opened in this state, the brake oil in the container 10 is continuously supplied to the master cylinder (not shown) via the reservoir tank 11.

On the other hand, if the reservoir tank 11 is attached to the side of the dash plate and its narrow inlet is inclined as shown in FIG. After rotating the seat 6 so that it is located at
The container 10 is held by three points at the tip. As a result, the container 10 attached to the end of the pipe 3 rising upward from the side body 2 of the on-off valve 1 is held at an inclination stronger than the inclination of the reservoir tank 11, and even in this case, The brake oil in the container 10 is completely discharged.

Furthermore, if the inlet of the reservoir tank 11 has a diameter large enough to insert the pipe 4 and the support rod 7, by inserting these into the inlet as they are, the supply container can be constructed as shown in FIG. As such, it is stably supported by the outer lower surface 6b of the seat 6 which abuts against the edges of the injection ports.

(Effects) As described above, according to the present invention, one pipe connected to the replenishment container and the other pipe connected to the replenishment port are connected at an obtuse angle. By simply changing the orientation, the replenishment container can be positioned above the replenishment port in a sufficiently inclined state.

In addition, a seating member is removably attached to the pipe that connects to the replenishment port, and a support rod is installed below the pipe along the pipe. It is possible to stably hold the replenishment container by extending the end of the support rod against the surrounding wall of the refilling port, and for wide-mouthed refilling ports, inserting the support rod into the refilling port reduces the appearance of the pipe. Commercially available replenishment containers can be easily attached to various brake oil replenishment ports depending on the vehicle model, such as by increasing the diameter of the top so that the replenishment container can be stably held by the outer lower surface of the seating member. Brake-related maintenance work can be performed with great ease.
