Air or fluid pumping system for driving hydraulic vehicles, has propulsion pumps, cock, container, pressure pumps, and mechanically or electrically driven piston pumps combined in piston pump engine to store energy for several applications

摘要

The system comprises of propulsion pumps for use as feed pumps, a cock for changing air or fluid flow, a container for storing and delivering applied energy, pressure pumps for exerting direct pressure to air or fluid, and mechanically or electrically driven piston pumps which are all combined in a piston pump engine (1). The system can store energy for several applications.
