ABSTRACT:
A reciprocating liquid or gas pump is driven by bi-directional force. A prime mover causes eccentric weights to rotate, which in turn cause pistons to be driven in linear paths under bi-directional force. This bi-directional force then drives opposing sets of pistons to pump a fluid. The pressurized fluid can then be used for, e.g., driving a hydraulic motor.
