Abstract: A damping element, particularly for a vehicle, includes first and second cylinder chambers, a cylinder and a connection element formed as a hollow body fastened to the end of the cylinder. A movable separating piston is arranged between the second cylinder chamber and the interior of the connection element for separating the region of the second cylinder chamber that is filled with hydraulic medium from a region of the connection element that is filled with a compressible medium. The connection element has a tube cross section having an outer diameter corresponding to the inner diameter of the cylinder and is inserted into the cylinder and tightly and fixedly. The separating piston is arranged so as to be coaxially displaceable in the cylinder and its displaceability is limited relative to the end region of the cylinder by the front side of the end region of the connection element.

Abstract: A spring plate, especially for a MacPherson strut unit, having an axial support surface for the final turn of a helical spring. The helical spring is centered by radial centering surfaces in the area of the circumferential contour of the final turn. The centering surface is divided into individual, partial centering surfaces, which come to rest against the circumferential contour of the helical spring.

Abstract: Piston-cylinder unit includes a piston rod guided with freedom of axial movement in a cylinder, where at least part of the piston rod is enclosed by a piston rod protector, which is designed with at least limited axial elasticity. At least one retaining surface of the piston rod protector enters into a positive connection with at least one stop surface on the cylinder side, and an auxiliary assembly bevel allows the piston rod protector to buckle over a certain stroke range of the piston rod during the installation of the protector, so that the retaining surface snap-locks onto the stop surface on the cylinder side.

Abstract: Mounting assembly for a vibration damper, comprising at least one aligning surface on the vibration damper side, which is in working connection with an opposing surface on the vehicle side at least during the installation of the vibration damper in a receiving opening in the vehicle. The at least one aligning surface and the opposing surface rotationally align the mounting side with the vehicle side. The aligning surface is arranged on a mounting cap with torque-transmitting element, and with at least one axial support surface for cooperation with the opposing surface on the vehicle side. The mounting cap prevents the vibration damper from falling out of the mounting assembly through the use of a carrier on the mounting side, to which the vibration damper is attached, this carrier having a retaining element in the form of a tongue which engages an opening in the mounting cap.

Abstract: A connecting bearing for a vibration damper includes a cup-shaped bearing housing, in which a disk-shaped transmission element with parallel top and bottom surfaces is provided, this element being attached to the vibration damper. Elastomeric bodies are arranged above and below the top and bottom surfaces, respectively, and a compensating element is provided to compensate for an angular offset between the vibration damper and a line perpendicular to a connecting surface of the connecting bearing. The compensating element is located between at least one of the elastomeric bodies and the transmission element.

Abstract: Vibration damper, in particular a shock absorbing strut, with an essentially U-shaped decompression stop boundary bracket, which bracket is fastened to a container tube, and in the event of a rebound of a vehicle axle comes into contact with a chassis-side support surface. The bracket includes a base plate with side walls, and the entire decompression stop boundary bracket is formed from a single bent component. The base plate is realized in a seamless manner and has a cutout which is adapted to the diameter of the container tube and acts as a positioning stop for the entire decompression stop boundary bracket.

Abstract: A fluid oscillation damper is provided with an electromagnetically controlled valve for varying the damping force of the oscillation damper. The electromagnetically controlled valve is housed within a compartment confined by two housing parts. A first housing part is fastened to a container of the oscillation damper A second housing part is fastened to the first housing part. Both housing parts are nonreleasably interconnected. The electromagnetically controlled valve is actuated by an electromagnetic coil. The electromagnetic coil is provided with a ferromagnetic core. This ferromagnetic core is constituted by a plurality of components. These components are assembled so as to reduce the magnetic resistance for the magnetic flux.

Abstract: A shock absorber with a check valve device and a check valve device for a shock absorber is disclosed. The check valve device located in the bypass of a shock absorber between a high-pressure segment and a low-pressure segment has a check valve which can be moved by an external control into a standby opening status, in which the actual opening can be performed as a function of the pressure prevailing in the high-pressure segment, when the pressure falls below a predetermined value. By coordinating the stroke distance of a check valve body with a magnet armature, and taking into consideration a control chamber discharge cross section, noises and fluctuations of the damping force characteristic can be eliminated even with a very soft comfort setting of the check valve device.

Abstract: Shock absorber with adjustable damping force, comprising a cylinder, an axially movable piston rod with a piston connected to it, a number of fluid chambers with capacities which can be changed relative to one another as a function of the movement of the piston rod relative to the cylinder, and fluid connections between at least two of the fluid chambers, whereby at least one of the fluid connections has a check valve module, whereby the check valve module is also designed with at least one valve seat, whereby a valve check element can be elastically applied against the valve seat in a check position, whereby this valve check element can also be adjusted by means of a field coil in opposition to the closing force of at least one spring in a number of positions, whereby the spring(s) is/are a unit of a row inside the check valve module, and possibly an intermediate module, which consists of a control chamber discharge valve body and a supplemental discharge valve body, characterized by a connection (17, 29, 15
