Abstract

A fluid pump (2) includes a piston (8) defining a fluid-charging chamber (CC) on one side and a fluid-pumping chamber (Cp) on the other. A one-way valve (Vp) carried on controls communication between the two chambers.Valves (V1, V0) are provided to open and close an inlet (41) of the fluid-charging chamber and an outlet (42) of the fluid-pumping chamber. During a return stroke, pressurized fluid from the fluid-charging chamber flows through the one-way valve in the piston supercharging the fluid-pumping chamber.
