ABSTRACT:
A rotary fluid pressure device is disclosed comprising a housing having fluid inlet and outlet means and enclosing a gerotor having an internally toothed member and a coacting externally toothed member having a less number of teeth than the internally toothed member and having its axis positioned eccentrically relative to the axis of the internally toothed member. A wobble stick in the housing has a first end connected to the axial drive shaft and a second end connected to the gerotor member having the orbital movement. The housing has one set of passageways communicating at all times with the expanding and contracting gerotor cells. The gerotor member having orbital movement is, in addition to its usual function, a valve with two travel passageways, one travel passageway coaxially surrounding the other passageway. These two travel passageways communicate at all times part of the set of passageways in the housing with only one fluid inlet or outlet while communicating other of this same set of passageways with the other fluid inlet and outlet. A star-pointed annulus increases commutation fluid flow. A laminated plate design facilitates the construction of the porting passages.
