Piston-cylinder unit for pressurizing medium operating device for motor vehicle, has guiding element connected with pressure area-sided end area, where element fixes defined position of piston and inhibits rotation of piston in cylinder

摘要

The unit (101) has a cylinder (102), and a piston (104) axially displaceable in the cylinder. The cylinder has a cylinder inner wall (103), where the piston limits a pressure area together with the cylinder wall within the cylinder. The piston has a pressure area-sided end area and a drive-sided end area. The piston is movable by a drive unit (110), and a guiding element (112) is connected with the pressure area-sided end area, where the guiding element fixes defined position of the piston in circumferential direction and inhibits rotation of the piston in the cylinder.
