  • Publication number: 20190293145
    Abstract: A pressure stop cap for a motor vehicle vibration damper includes a disk-shaped end portion which is formed in an end area of the pressure stop cap and forms a rebound surface for an impact absorber, a tubular portion extending axially from the disk-shaped end portion, and at least one vent opening which is arranged adjacent to the end portion in the end area of the pressure stop cap and extends radially through the tubular portion. The pressure stop cap has a groove-like circumferential recess which is formed at its outer surface and which divides the outer surface of the pressure stop cap axially into a first pressure stop cap portion and a second pressure stop portion, the first pressure stop cap portion being formed in the area of the end portion.

  • Patent number: 8418821
    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.
