Patent ID: 8123005

Claim:
An end-stop damper having a damper body ( 10 ) with a cylinder ( 11 ), the end-stop damper comprising: a sliding element having one-piece construction comprising an impact element ( 41 ), a piston rod ( 42 ), and a piston ( 43 ); a support body ( 30 ) having a first end toward the impact element ( 41 ) and a second end adjacent the piston ( 43 ), the support body including a sheath element ( 31 ) surrounding the piston rod ( 42 ) and spaced apart from an inner side wall ( 18 ) of the cylinder ( 11 ), wherein the impact element extends beyond the first end of the support body ( 30 ) and is at least partially deformable into the support body ( 30 ) upon impact, and the second end of the support body ( 30 ) comprises a radially widened shoulder ( 32 ) supporting the support body ( 30 ) on the piston ( 43 ); wherein the piston ( 43 ) and the sheath element ( 31 ) are displaceably guided in a receiving chamber ( 11 . 1 ) of the cylinder ( 11 ), a braking force acting on the piston ( 43 ) is exerted by an air pressure generated in the receiving chamber during displacement of the piston ( 43 ), the receiving chamber ( 11 . 1 ) is connected with a surroundings through at least one opening ( 16 ) for relieving the air pressure, and the piston ( 43 ) has a bellows section ( 44 ) in operational connection with the cylinder ( 11 ) as a function of pressure conditions in the receiving chamber ( 11 . 1 ), and the piston ( 43 ) and the bellows section ( 44 ) are connected with each other in one piece; and a ratio of a cross-sectional surface of the piston ( 43 ) in an area facing the hollow chamber to an opening cross section of the opening ( 16 ) being greater than 4000/1.
