Abstract
Methods and systems for a mechanically driven pump are provided. The mechanically driven pump may apply a piston simultaneously to operate as a guillotine blocking valve and a component to transfer motive force. A spring may apply a force to the piston to oppose a force that is applied to the piston via a cam lobe. The mechanically driven pump exhibits a differential pressure at a calibrated orifice during two working phases of the pump (expansion and compression), which provides for a non-zero volumetric efficiency of the mechanically driven pump.
