Abstract
For a hydraulic actuation arrangement of a motor vehicle friction clutch a hydraulic cylinder is proposed of which the cylinder, displaceably receiving a piston (7), consists of a synthetic plastics material moulding (3) and a tube piece (5) of metal arranged in the moulding (3) and guiding the piston (7). The tube piece (5) is cut off from a semi-finished tube and guided with axial play, but with resilient initial stress, in the moulding (3). Seals (27, 49) arranged at the ends of the tube part (5) seal the tube part (5) off from the moulding (3).
