ABSTRACT:
The invention relates to a fluid pressure operated motor or pump of the type having a gerotor displacement mechanism which normally includes inner and outer wheel and ring gears which in operation have relative rotational and orbital movement therebetween. Such devices inherently have a form of valving wherein, with a commutating type of action, fluid is directed from the casing inlet to expanding chambers of the gerotor and directed from collapsing gerotor chambers to the casing outlet. In the unit herein the commutator valving includes two valve plates attached to opposite sides of the orbiting and rotating wheel gear which have the commutating action with the surrounding stationary ring gear.
