AI Technical Summary

Benefits of technology

The invention includes a cylinder that can rotate between a fixed housing and rotating vanes. This reduces friction and drag between the vanes and the housing, which helps to prolong the life of the pumps and motors. The cylinder only rotates when the pressure within a chamber exceeds the force of frictional drag between the vanes and the cylinder. Overall, this technology improves the performance and durability of vane pumps and motors.

Problems solved by technology

It further prolongs the life cycle of vane pumps and motors.

Embodiment Construction

[0017]FIG. 1 illustrates a radial vane pump or motor device 10.

[0018]The device 10 has a stationary housing 12 with a chamber 14.

[0019]A cylinder or cylindrical drum or sleeve 16 is disposed within the chamber 14. The cylinder 16 has a central cylinder axis A. The cylinder 16 is rotatable about the axis A relative to the stationary housing 14. Support for rotation may be provided by a bearing 18. The bearing 18 may take the form of a plurality of rollable elements, such as roller or ball bearings disposed between the outer surface of the cylinder 16 and the inner surface of the housing chamber 14 to provide low friction support of the cylinder for free rotation relative to the housing 12. The inner surface of the cylinder 16 defines a cylindrical space in which a rotor 20 is disposed. The rotor 20 is cylindrical and smaller in diameter than that of the cylindrical space of the cylinder 16. The rotor 20 is mounted on a shaft 22 for rotation therewith. The shaft 22 is supported by the...

Abstract

A radial vane pump or motor device includes a stationary housing provided with a cylinder supported for rotation relative to the housing about a central axis. A rotor is fixed to a shaft for rotation with the cylinder about an axis offset or eccentric relative to the central axis. A plurality of vanes slide radially in the rotor for contact with the inner surface of the cylinder.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This U.S. Utility Patent Application claims priority to U.S. Provisional Patent Application No. 62 / 780596, filed Dec. 17, 2018, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION1. Technical Field[0002]This invention related generally to vane pumps and motors.2. Related Art[0003]Radial vane pumps and motors are known in which a rotor is disposed within a fixed housing and mounted on an off-center shaft. Slideable vanes are supported by the rotor and slide in and out to maintain contact with the inner housing wall. The rotation of the vanes in contact with the housing creates chambers of changing volume. In the case of a pump, fluid enters the housing at a large chamber and is forced to exit under pressure through an outlet at a smaller chamber. The opposite occurs in the case of a motor, wherein fluid enters at a small chamber and exits at a large chamber while imparting rotation to the shaft via ...
