发明名称 Piston pump with variable eccentricity
摘要 <p>The pump has displacing units (6) movable from a mantle surface (18) of an eccentric sleeve (17) against fluid pressure, where the displacing units are movable radial to a main axis (16) of the pump. A spring unit (39) acts on the eccentric sleeve in an axial direction, and a pump shaft section (23) is formed as a narrow eccentric pin (24) with an eccentric pin axis (25), which runs to the main axis at an angle of inclination (26). The eccentric sleeve is guided to the eccentric pin and has a cylindrical mantle surface whose ends (20) run parallel to the main axis. An independent claim is also included for a method for driving a fluid driven motor of a hydraulic cylinder or a hydraulic motor.</p>
