  • Hydraulic cylinder for controlling a friction clutch in a motor vehicle
    Patent number: 11841055
    Abstract: A hydraulic cylinder is provided which has a body forming a hydraulic chamber, in which a tubular piston made of thermoplastic material slides. An insert is locked in an internal cavity of the piston and has a spherical seat configured to receive and retain a spherical head of a rod connectable to a control pedal. The insert is made of thermoplastic material and forms a plurality of flexible fins adjacent to the spherical seat. The flexible fins have retaining elements protruding in a radially internal direction to hold the spherical head of the rod. A tensile force exerted by the rod away from the insert is transferred to a body of the piston by a stop ring.
