ABSTRACT:
A radial piston pump includes a plurality of radially arranged cylinder-pger assemblies having suction valves and pressure-regulating valves, with the plungers being controlled by an eccentric disk which eccentrically circulates relative to a housing accommodating the cylinders. In order to provide a radial piston pump of this type with a simple design and to allow a digital operation of the pump for controlling the flow rate, the space between the end faces (12) of the cylinders (9) and the pertaining plungers (7) is connectable with a pressure manifold (19) of the pump by a randomly controllable valve (21, 22), with the plungers (9) of the pump preferably having different diameters.
