ABSTRACT:
A fluid pump wherein the pumping action is created by reciprocating forces applied to an unattached block, such as a ball, of elastically deformable material in a cavity, such as a cylinder. The block effects the pumping by defining a fluid pumping enclosure in said cavity, the cavity being additionally provided with means effecting the deformation of said block during said reciprocatory force cycle, thereby storing energy which is advantageously recovered in the pump intake stroke.
