される回転型ポンプのひとつであるベーンポンプに関す
る。TECHNICAL FIELD The present invention relates to a vane pump which is one of rotary pumps used in superchargers, compressors and the like.
従来から、第5図に概略構成を示すようにベーンポンプ
が広く知られている。Conventionally, a vane pump is widely known as shown in the schematic configuration of FIG.

体を吐出口(38)から吐出させる。In the figure, (31) is a housing, (32) is a rotor which is inserted into the inner peripheral space of the housing (31) in an eccentric state and is rotatably supported by a rotating shaft (33), (35
a) (35b) (35c) are vane grooves (34a) (34a) that are equally recessed so that the outer peripheral side of the rotor (32) is divided into three in the circumferential direction.
b) A plate-shaped vane that is disposed in (34c) so as to be capable of projecting and retracting in the radial direction. When the rotor (32) rotates in the direction of the arrow (X) in the figure by the rotating shaft (33), the vanes (35a) (35b) (35
The centrifugal force c) protrudes in the outer diameter direction, and its tip edge rotates while slidingly contacting the inner peripheral surface of the housing (31).
As described above, since the rotor (32) is eccentric with respect to the housing (31), the housing (31), the rotor (32) and the vanes (35a) (35b) (35) are accompanied by this rotation.
The volumes of the operating spaces (36a) (36b) (36c) partitioned by c) are repeatedly expanded and contracted, and the fluid sucked from the suction port (37) is discharged from the discharge port (38).

てハウジングの軸方向両内側面とのかじりが生じること
があり、摩耗も著しいといった問題があった。However, in the above conventional vane pump, since the vane slides on the inner peripheral surface of the housing at a high speed, it is unavoidable that the rotation efficiency is deteriorated due to the sliding resistance between the tip edge of the vane and the inner peripheral surface of the housing. Due to the sliding heat generation, the volumetric efficiency of the conveyed fluid is inevitably decreased, and the vanes may expand to cause galling with both inner side surfaces of the housing in the axial direction, resulting in significant wear.
本発明は、このような問題に鑑み、摺動による抵抗の発

る。In order to achieve this object, the vane pump of the present invention has a rotor rotatably supported eccentrically in the inner peripheral space of the housing and a plurality of vane grooves recessed in the rotor so as to project and retract. In a structure having a plate-shaped vane provided and sucking fluid from one side and discharging it to the other side by utilizing the repeated volume change of the working space between the vanes accompanying the rotation of the rotor and the vane, A retainer plate is rotatably fitted and inserted in an annular recess formed coaxially with the inner peripheral space inside the end wall of the housing, and the retainer plate and each vane are connected by a cam that is angularly displaceable to the vane groove. The vane plunging movement is restricted within a certain range.

回転させることができる。According to the present invention, the protrusion of the vane from the vane groove is not restricted by the contact with the inner peripheral surface of the housing, and the vane rotating together with the rotor is linked to the retainer via the cam. Since the rotor rotates synchronously with the rotor and the retainer and the rotor are in an eccentric relationship, the cam is periodically angularly displaced so as to swing to both sides of a straight line passing through the rotation center of the retainer and the swing center of the cam. The angular displacement motion of the vane causes the vane to perform a plunging motion with respect to the vane groove within a certain amount of movement.
The vane can be rotated in non-contact with the inner surface of the housing.

間が介在するように突没運動させることができる。Next, the operation of the vane pump will be described. When the rotating shaft (10) and the rotor (4) are rotated by the driving force from the pulley (9), the vanes (11a) (11b) (11c)
The vane (11a) (11b) (11c) also rotates and the cam (1
Torque is transmitted to the retainer plates (14a) (14b) via 6a) (16b) ... (17c). The retainer plates (14a) (14b) rotate coaxially with the inner peripheral surface of the housing, and the retainer plates (14a) (14b)
The cams (16a), (16b), ... (17c) fitted in the recesses (22a), (22b), ... (23c) of the rotor also rotate coaxially with the inner peripheral surface of the housing, and the rotation thereof is the rotor. Fully synchronized with (4). As described above, since the rotor (4) is eccentrically mounted on the inner peripheral surface of the housing, the vanes (11a) and the cams (16a) (17a) that overlap at the top position are rotated. It will shift (however, the vane (11
(a) overlaps again at the bottom position (180 ° symmetrical to the top position) where it most jumps out of the vane groove (12a), and this displacement causes the retainer plate (14a) via the cams (16a) (16b) ... (17c). ) (14b), the vanes (11a) (11b) (11c) are connected to the vane groove (12) of the rotor (4).
a) (12b) (12c) slid in the radial direction and repeatedly projecting and retracting, partitioned by both housings (1) (2), rotor (4) and vanes (11a) (11b) (11c) The volume of the space (5) is repeatedly increased and decreased to transfer the fluid from the suction port (not shown) to the discharge port. In the above-mentioned operation, the vanes (11a) (11b) (11c) have the vane grooves (12a) (12b) (12).
Since the protrusion from c) is restricted and the tip edge rotates without making contact with the inner peripheral surface of the housing, it is possible to prevent torque loss and prevent wear and heat generation. Also,
Since the cams (16a) (16b) ... (17c) only make angular displacement movement relative to the retainer plates (14a) (14b), the retainer plates (14a) (14b) and the vanes (11a) ( 11b) (11c) has very little wear at the joint, and therefore vanes (11a) (11b) (11c)
It is possible to make a projecting and retracting motion such that a constant minute gap is always present with respect to the housing inner peripheral surface (1 ').

のみを付して説明を省略する。FIG. 4 shows another embodiment of the present invention, in which the second pins (20a) (21a) of the cams (16a) (17a) overlapping the vanes (11a) at the top position are the first pins (18a) ( 19a) located closer to the inner edge than each vane (11
a) Engagement recess (26a) formed on the side edge of (11b) (11c)
(26b) ... (27c) are provided near the inner end of the side end. Since other configurations are the same as those of the first embodiment, only the reference numerals are given and the description thereof is omitted.

It regulates the amount of submerged movement.The cam only repeats angular displacement with respect to the retainer plate and vane, and wear of the connecting part with the retainer plate and vane is extremely small. However, it is possible to rotate through a constant small gap at all times, prevent rotation efficiency deterioration due to sliding resistance and vane wear, and cause problems such as volume efficiency deterioration due to increased sliding heat generation. It has an excellent effect of being able to prevent
