Abstract

An axial plunger pump for high pressure purposes using three plungers in a star like arrangement around an axis of a wobble plate. Each plunger has associated therewith a pumping unit and all pumping units are located in a common pumping unit block and each of the pumping units comprising a pump chamber having inlet and outlet valves connected to a common inlet duct and outlet duct respectively. Plunger cylinders of at least one of the plungers are connected to pump chamber at a position between the inlet valve and the outlet valve while the plunger cylinder of at least another plunger is connected to the associated pump chamber at a position below the inlet valve.
