  • Patent number: 12209600
    Abstract: An assembly for a fluid-filled piston-cylinder unit comprises a main body having an assembly longitudinal axis (24), a valve unit integrated in the main body and having an overflow channel, which valve unit seals the overflow channel when the assembly is moved along the assembly longitudinal axis in a first direction and releases the overflow channel, in dependence on the fluid pressure, when the assembly is moved along the assembly longitudinal axis in a second direction. Furthermore, the assembly comprises an outer seal element that is arranged on the main body so as to be moved along the assembly longitudinal axis, for abutting in a sealing manner against an inner surface of the housing, and at least one undercut element formed on the main body for engaging in an interlocking manner behind a mating element of the piston-cylinder unit.

  • Publication number: 20230272657
    Abstract: A drive arrangement for a motor vehicle flap including a gas pressure element, the gas pressure element has an outwardly sealed cylinder and a piston moveable in the cylinder interior along the cylinder axis and subdivides the cylinder interior into two sub-chambers, the gas pressure element has a first drive connection connected to the cylinder, and a second drive connection connected to the piston, the cylinder filled with a fluid and the piston has an overflow channel arrangement to create a balancing flow between the two sub-chambers to balance a pressure drop between the two sub-chambers. The piston is assigned a switchable valve arrangement which, depending on the pressure drop between the two sub-chambers, to create different through-flow states differing the cross section of the overflow channel arrangement. Upon exceeding a predetermined threshold for the pressure drop, the valve arrangement switches to change the cross section of the overflow channel arrangement.

  • Patent number: 10544847
    Abstract: A damper includes a housing with at least one axially offset longitudinally extending guide channel for receiving a plunger of a piston assembly. The plunger is axially offset from a control rod extending through the housing and the piston assembly. A coil spring surrounds the housing and extends between a hemispherical cap of the housing and the piston. The plunger includes a friction pad which engages the guide channel of the housing to provide frictional inter-engagement for the damper. In one embodiment, the housing includes a pair of axially offset guide channels and the piston assembly includes a pair of axially offset plungers which extend within a pair of guides of the housing. One of the plungers includes a linear sensor which provides signal information for use by a washer control circuit.
