STOP DAMPER

摘要

The invention relates to a stop damper comprising a damper member (10) that is provided with a cylinder (11). A piston (43) is movably guided inside a receiving space (11.1) of the cylinder. The cylinder (11) has a sliding surface (8) against which the piston (43) rests with a sealing element. A braking force that acts upon the piston (43) can be applied using the air pressure generated in the receiving space (11.1) because the piston (43) is displaced, the receiving space (11.1) being connected to the environment via an air-conducting connection so as to reduce the air pressure. In order to improve the braking effect of the sliding element, the sealing element of the piston and the sliding surface of the cylinder can be in contact with each other in at least some areas via a defined rubbing surface geometry, the peak-to-valley height of the sliding surface R_a = 1 µm and the peak-to-valley height of the facing surface of the sealing element being = 4,5 µm in at least some areas.
