ABSTRACT OF THE DISCLOSURE Rectangular pistons are driven in a circular orbit by two spaced eccentrics on a common crankshaft. The displacement chambers reciprocate with a lateral motion parallel with the crankshaft. The radial forces created by the fluid pressure in the displacement chambers are balanced by a connection to the crankshaft through rotatable and slidable antifriction bearings. During the reciprocating lateral motion of the chambers, port openings located in the outer ends of the chambers are connected alternately to matching intake and exhaust port openings in the adjacent surfaces of the casing to provide a reversible valveless control of the fluid to and from the chambers. The apparatus can be used either as a pump or motor without internal modifications. The pistons are secured together as one piece and follow identical orbital paths. Each pair of opposing displacement chambers are secured as one piece and radially connected to the crankshaft. The displacement of the apparatus is continuously variable from zero to its maximum. The apparatus is dynamically balanced by two counterweights, with adjustable eccentricities. v1-902-1
