ABSTRACT:
A device capable of functioning as a fluid pump or motor has a shaft provided with an eccentric rotating with the shaft in an axially short cylindrical chamber. A ring is rotatable on the eccentric, the thickness of the ring being close enough to the minimum distance from the periphery of the eccentric to the wall of the cylindrical chamber to cause the ring to roll along the wall on rotation of the shaft. The presence of the bearing interposed between the ring and the eccentric has the effect of adding to the thickness of the ring in this relationship. A high pressure and a low pressure port are closely spaced about the chamber periphery, and a moveable dam is mounted between these ports. A second moveable dam is mounted on the opposite side of the high-pressure port from the first dam.
