Abstract

1. Servo adjustment device for an adjustable hydraulic machine with a control element (42), which can be randomly displaced by means of an actuation device and controls a pressure medium control stream for a device which actuates the correcting element (14) of the hydraulic machine and has at least one partially hollow adjustment piston (15), and with a control slide valve (47), which controls, together with the control element (42), a pressure space at the adjustment piston, characterized in that the adjustment piston (15) is guided with its inside against a guide body (18), and in that the pressure medium control stream is separated from the pressure medium contained in the housing of the hydraulic machine by means of a bellows (25) fixed on the adjustment piston and on a neighbouring housing wall (24).
