Abstract

A hydrostatic machine comprises a shaft, a rotor arranged on a shaft for rotation and having radially extending opening, a plurality of pistons arranged in the radial openings and having ends extending outwardly beyond the openings, a displacement curve arranged so that the ends of the pistons slide on the curve, channels for communicating the openings with a pressure medium and including passages which open laterally at the rotor, and a device for compensating an axial thrust applied by a pressure medium to the rotor and including pressure medium-actuated additional pistons.
