摘要： The invention relates to a method for operating a controllable shock absorber (1), in particular for a vehicle suspension. The shock absorber comprises a cylinder pipe (10) with a hydraulic fluid sealed therein, a piston (2), which can be moved axially inside the cylinder pipe (10) along a cylinder pipe axis (A) and which sub-divides the cylinder pipe (10) into two working chambers (11, 21), and a piston rod (3) running parallel to the cylinder pipe axis (A) and connected to the piston (2). The piston (2) has at least two fluid passages (12, 22), by means of which one working chamber (11, 21) is connected to the other working chamber (21, 11); a first valve arrangement (13) is located at a first fluid passage (12) in order to damp the movement of the piston in a first actuation direction (R1) and a second valve arrangement (23) is located at a second fluid passage (22) in order to damp the movement of the piston in a second actuation direction (R2). Each valve arrangement (13, 23) has at least one valve plate (14, 24) which rests on a valve seat (15, 25) when the valve is in a closed position and which is at least partly at a distance from the valve seat (15, 25) when the valve is in an open position. Each valve arrangement (13, 23) comprises a pilot chamber (16, 26) and the respective valve plates (14, 24) can be pre-tensioned into the closed position of the valve by the application of pressure to the pilot chamber (16, 26). The pressure in each pilot chamber (16, 26) can be adjusted by at least one pilot valve (31), said pilot valve (31) comprising a valve body (32) that can be moved in a defined manner between a closed position and an open position, as a result of which an outflow cross-section between the pilot chambers (16, 26) and the working chambers (21, 11) can be adjusted in a specific manner. A dynamic pressure (p) can be applied in a defined manner to the valve body (32) on the outflow side, as a result of which the movement of the valve body (32) is damped.

摘要： The invention relates to a powder-metallurgically produced piston body for a piston-cylinder arrangement, particularly shock absorber pistons, comprising a one-piece piston body (6), the peripheral surface of which is provided with a revolving web (12) in a region bordering a final piston area (4.1). Said revolving web (12) protrudes the peripheral surface and is adjacent to longitudinal support webs (10) which extend to the other final piston area (5.1) and are disposed parallel to and at a distance from each other, and at least some of which are provided with at least one transversal groove (11.1) between the two final piston areas (4.1, 5.1). Two neighboring support webs (10) delimit a groove-shaped recess (11) which is open in the longitudinal direction at the end opposite the revolving web (12). A collar-shaped seal (9) made of a thermally deformable sealing material can be shaped onto the piston body (6) such that both the revolving web (12) and the support webs (10) are formed into the material of the collar-shaped seal (9) in the vertical direction, at least across a portion thereof.

摘要： A damper includes a piston and a cylinder housing the piston, and generates a braking force based on a movement or relative movement of the piston. The piston includes a trunk portion and a seal ring surrounding the trunk portion. A first seal portion against an inner wall of the cylinder is formed on an outer peripheral portion in the seal ring, and a second seal portion against a circumference wall portion projecting from the trunk portion is formed in a front end portion positioned on a pressure chamber side. Also, a support rib portion is provided outside the trunk portion, which allows the seal ring to move within a predetermined range along a moving direction of the piston in a state wherein a movement gap for a fluid is formed between the trunk portion and an inner peripheral portion of the seal ring.
