Cylinder-End-Cap

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. The cross section of the first pressure stop cap portion is larger than the cross section of the pressure stop cap in the area of the circumferential recess, and the cross section of the second pressure stop cap portion is larger than the cross section of the pressure stop cap in the area of the circumferential recess.
