摘要： A hydraulic cylinder for a hydraulic clutch actuating system for motor vehicles has a piston subassembly with a piston and piston rod, a cylinder housing in which a pressure chamber is variably bounded at one side by the piston and fixedly bounded at the other side by a base of the cylinder housing. A spring element is arranged at the side of the piston opposite from the pressure chamber and is supported at one end on a spring plate on the housing side and operatively connected at the other end with the piston rod so as to bias the piston subassembly in a direction away from the base. A fixing section fixes the piston subassembly in a predetermined stroke setting with respect to the cylinder housing prior to first actuation of the hydraulic cylinder and is constructed to release the piston subassembly relative to the cylinder housing upon first actuation.

摘要： A slave cylinder for a vibration-damped hydraulic force transmission system, particularly a hydraulic clutch actuating system for motor vehicles is disclosed, comprising a cylinder housing, a piston received therein to be longitudinally displaceable and a pressure chamber which is bounded by the cylinder housing and the piston and which can be selectably acted on by a pressure medium, by way of a pressure connection provided in the cylinder housing, in order to displace the piston in the cylinder housing. An insert member which is inserted in the pressure chamber and secured in the pressure connection and which is equipped with a device for reducing pressure pulses, the device being constantly open to the pressure medium, is additionally provided. As a result, the vibration-damping measures or means are integrated in the slave cylinder in a particularly economic and space-saving manner.

摘要： A hydraulic cylinder has a cylinder housing in which is formed a pressure chamber variably bounded on one side by a piston of a piston subassembly that is longitudinally displaceable. A piston rod is rigidly connected with the piston, wherein the piston has an outer contour, which permits tilting of the piston subassembly in the cylinder housing, and a projection, which is at the pressure chamber side and on which a sealing element is centered and retained by a retaining ring. The sealing element has an encircling sealing lip that slidably and sealably bears against a sliding surface of the cylinder housing. The retaining ring is provided on the side thereof opposite from the sealing element with a stiffened prolongation.
