Abstract

PURPOSE:To prevent the generation of sliding heat, by providing retainer plates to be mounted to the insides of both end walls of housings while protrusively providing stoppers in peripheral end parts of said retainer plates and restricting vanes from springing out due to rotation by the stoppers. CONSTITUTION:Retainer plates 14a, 14b are provided to be rotatably mounted through ball bearings 16a, 16b to inner side surfaces 1', 2' in both walls of housings 1, 2. The retainer plates form in their peripheral end parts annular stoppers 15a, 15b restricting vanes 11a-11c from springing out. Accordingly, the generation of sliding resistance and sliding heat can be prevented by placing the vanes so as to rotate in a contactless condition with the housing.

However, in the conventional vane pump mentioned above, since the vanes slide at high speed on the inner circumferential surface of the housing, not only is it impossible to avoid the generation of high sliding heat and a significant decrease in volumetric efficiency due to sliding resistance, but also it is difficult to avoid wear. The progress is also significant, and the vane expands due to the heat generated by sliding, causing problems such as galling with both axial ends of the housing.

That is, in the vane pump according to the present invention, retainer plates are installed inside both end walls of the housing so as to be rotatable and coaxial with the inner circumferential surface of the housing, and the retainer plates are prevented from rotating by stoppers protruding from the outer circumferential ends of the retainer plates. The configuration is such that the accompanying protrusion of the vane is restricted.

According to the present invention, the vane, which is ejected from the vane groove due to the centrifugal force accompanying the rotation, rotates without contacting the housing as both axial ends of the leading edge of the vane come into contact with the stopper. Here, since the retainer plate also rotates together with the rotor and the vanes, relative sliding between the vanes and the stopper can be kept small.

The above embodiment has a structure in which the retainer plate is rotated in synchronization with the rotor using a cam, but a similar structure may be used in which the retainer plate is rotated in approximately synchronization with the rotor by the frictional force between the vane and the stopper. It is effective. Further, in the above embodiment, the stopper is formed in an annular shape, but when the retainer plate is rotated in synchronization with the rotor using a cam, the contact portion of the stopper with the vane is limited, so the stopper is made elastic so as to correspond to the chain portion. It may be formed into a shape.

As explained above, (1) the vane pump of the present invention restricts the protrusion of the vane by the stopper at the outer peripheral end of the retainer plate rotatably provided inside both end walls of the housing, and the vane is kept in a non-contact state with respect to the housing. This makes it possible to minimize the reduction in pump efficiency and progression of wear due to sliding resistance and high sliding heat generation, and also to lower the temperature of the fluid discharged from the pump, which improves engine performance. It exhibits excellent performance when used in superchargers and other devices.
