Embodiment Construction

[0029] The following descriptions are merely exemplary of the invention in nature, and are not intended to limit its disclosure, application, or uses. For the sake of clarity, the same reference numerals in the figures, with or without the addition of one or more apostrophes, refer to similar compositions. Words in this text referring to at least one of A, B and C should be interpreted as a logical relationship (A or B or C) using the non-exclusive logical word "or". Unless otherwise indicated, the steps of the recited methods may be performed in different order without departing from the principles of the present invention.

[0030] Gerotor pumps in accordance with the disclosure herein can provide hydraulic force to a mechanical drive system. The Gerotor pump includes a drive shaft that meshes with the inner rotor. The inner rotor is located inside the outer rotor, and together with the outer rotor forms a rotor set. The inner rotor may be an inner rotor assembly that inc...

Abstract

A gerotor pump having an outer rotor defining an inner surface of the outer rotor, a thrust plate, a pressure plate, an inlet chamber for fluid intake through the thrust plate to be pressurized, and an outlet chamber for outputting pressurized fluid from the pressure plate. The gerotor pump includes an inner rotor assembly in rotating engagement with the outer rotor. The inner rotor assembly rotating about an axis, the inner rotor assembly comprises a rotor body, wherein the rotor body includes N (an integer greater than one) vane slots defining a first sealing surface, and the rotor body includes N inner openings around the axis, each of the inner opening adjoining a vane slot; and a plurality of vanes defining a second sealing surface, wherein the vane is disposed in the vane slot and in sealing engagement with the rotor body via the first and second sealing surfaces. The inner rotor assembly is in sealing engagement with the outer rotor by the vane engaging on the inner surface of the outer rotor.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application has the benefit of US Provisional Patent Application No. 61 / 305,211, filed January 26, 2010.
