Abstract
The invention relates to a radial piston pump of the type in which a piston carrier, together with an end slide plate within a track carrier, produces one piston stroke per revolution. The piston carrier is rotatably disposed between two parallel housing surfaces and has distributing passsages opening at the end and cooperating with distributing apertures at the pressure and suction sides in at least one housing surface. At least one pressure surface, which is bounded by sealing rings, is in communication with the pressure side to force the piston carrier and slide plate apart. An annularly shaped corrugated spring is provided for aiding and supplementing the pressurized fluid in also pressing the piston carrier and slide plate apart.
