Abstract
A positive displacement pump is disclosed having a pump body, a cylinder member rotatably accommodated within the pump body and a piston member within the cylinder member. At least a portion of the cylinder member is rotatable about the cylinder axis in step with the reciprocal motion of the piston relative to the cylinder. The rotatable portion of the cylinder has as least one flow port which communicates with the working volume of an intake or discharge port for material being pumped. The rotatable portion of the cylinder preferably has two flow ports, one which will communicate with the intake port and the other which will communicate with the discharge port.
