Abstract
A gerotor assembly includes a pressure chamber with an integral eccentric ring for a motor vehicle hydraulic differential for use in hydraulic limited slip differentials for axles, transfer case center differentials and similar devices. The gerotor pump assembly in accordance with the present invention includes a housing having an integral ring which provides a pressure chamber for a piston, an eccentrically positioned recess for a inner rotor and an outer rotor and a location for a pressure limiting system. The gerotor pump assembly is of a non-reversing gerotor pump configuration using known methods to produce a unidirectional fluid flow.
