Shock absorbers and vibration dampers; and shock absorbers and vibration dampers with a piston with a piston ring; and a cylinder with a piston with a piston ring

摘要

A shock absorber with an affixed or clamped-on piston ring for a piston-cylinder unit, whereby the piston ring covers a lateral surface of the piston and creates a seal with respect to the cylinder, characterized by the fact that the piston ring has a width which is greater than the lateral surface, so that there is a projecting end of the piston ring with respect to the piston, which projecting end is shaped into a spring end which is supported on the cover side on the piston.
