Patent ID: 8485325

Claim:
An end stop damper with a damper body, comprising: a cylinder including a reception chamber, the reception chamber having an inner sliding surface surrounding a volume of air; a groove that is cut into the sliding surface, the groove extending transversely with respect to a movement direction of the piston and having a first peak-to-valley height Ra<1μm; a piston including a sealing element, the sealing element including a sealing element surface facing the sliding surface and touching a portion of the sliding surface, the sealing element surface having a second peak-to-valley height of ≦4.5 μm; wherein the piston is displaceably guided inside the reception chamber of the cylinder, the sealing element is in contact with the sliding surface, and with a displacement of the piston a braking force acting on the piston can be exerted by an air pressure formed in the reception chamber; and an air guidance connection connected with an environment surrounding the end stop damper adapted to release the air pressure within the reception chamber.
