Abstract
In a pressure medium operable cylinder/piston unit for the provision of at least one rotary movement, comprising a cylinder bore (8) having inside it a radially internally projecting partition wall (4) and a vane piston (5) which projects radially outwardly from a piston rod (3) extending through the cylinder housing (2) and forms two alternately pressurisable radial pressure chambers (26 and 27), the radial partition wall (4) and the radial vane piston (5) are arranged on the piston rod (3) adjacent an axial piston (6) which, together with the cylinder bore (8), forms outer pressure chamber (14), and the radial partition wall (4) is arranged in the cylinder (2) so that, by way of a projection (18), it is secured against rotation.
