摘要： An annular sealing element (16) for sealing an annular gap between the inner surface of a cylindrical wall and a cylindrical piston which can be displaced axially relative to said wall and is arranged concentrically therewith, has two separate annular and axially adjoining parts (42, 44), of which the first part (42) consists of an elastomer material and the second part (44) consists of a rigid material. In order to ensure, in conjunction with a displaceable body of a valve, that the opening and closing behavior of the valve is as constant as possible, the two parts (42, 44) are connected to one another in a releasable manner, and the part (44) made of rigid material has an axial protrusion (46) which is formed integrally with it, runs around it in the form of a ring, passes more or less to the full extent through the part (42) made of elastomer material and has its end surface covered over to the full extent by the part (42) made of elastomer material. The axial protrusion (46), which runs around in the form of a ring, is designed and arranged such that a radial wall thickness Si of the part (42) made of elastomer material, on the radially inner flank of said protrusion, is approximately equal to a radial wall thickness Sa on the radially outer flank of said protrusion. The radial extent S of the protrusion (46) is not more than 70% of the sum of the wall thicknesses Si+Sa.

摘要： A master cylinder (10) for a vehicle hydraulic brake system has a housing (12) with a bore (14) formed therein, which is open at one end and in which a first pressure piston (16) and a second pressure piston (18) are guided sealingly and displaceably along an axis (A). Acting counter to an actuating direction (X) upon the first pressure piston (16) is a restrained first restoring spring (34) and upon the second pressure piston (18) a second restoring spring (52). In order, in a transportation or disassembly state of the master cylinder (10), to prevent the first pressure piston (16) from being pressed excessively out of the bore (14), the second pressure piston (18) is supported by means of a stop component (66) counter to the actuating direction (X) positively in the housing (12) of the master cylinder (10).

摘要： A sealing element seals a pressure piston which is movably arranged in a housing of a brake cylinder. The sealing element may be inserted into a ring-shaped groove which is provided in the housing. The sealing element includes an outer sealing lip for contact with a floor of the ring-shaped groove, an inner sealing lip for contact with the pressure piston, and a sealing element back. At least one non-sealing spacer element is provided on the sealing element back.

摘要： A master cylinder includes a restraining device arranged between the first and second pistons for preventing the return spring from being compressed and expanded beyond a certain extent. The restraining device includes a first, substantially sleeve-shaped component and a second, substantially pin-shaped component. The pin-shaped component includes a flange which projects radially outwards. The sleeve-shaped component includes a first receiving flange which positively interacts with the flange of the pin-shaped component. The sleeve-shaped component includes at least one introduction opening which enables the flange on the pin-shaped component to be laterally introduced into the sleeve-shaped component. The end of the sleeve-shaped component includes a second receiving flange which positively interacts with a flanged projection on the second piston which projects radially outwards. The sleeve-shaped component includes the at least one introduction opening which enables the flange provided on the second piston to be laterally introduced into the sleeve-shaped component.
