Patent ID: 7243398

Claim:
A pivot-action damper comprising an outer cylindrical body ( 1 ) which encompasses an inner body ( 2 ) which is rotatably-mounted in relation to said outer cylindrical body ( 1 ), wherein between the bodies ( 1 , 2 ), there are two chambers ( 25 , 26 ), separated from each other and interconnected by a gap ( 17 ) or throttle position solely and continuously defined between a contraction ( 16 , 30 ) on an inner surface of said outer body ( 1 ) and an outer surface of said inner body ( 2 ), said chambers ( 25 , 26 ) containing a fluid, said fluid being displaced from one chamber to the other as a result of the rotation of the two bodies ( 1 , 2 ) in relation to each other, the two bodies ( 1 , 2 ) which are pivotable in relation to each other are rotatable on a common axis, the inner body ( 2 ) around a circumference thereof comprises a cylindrical section ( 4 ) with a larger radius and a cylindrical section ( 3 ) with a smaller radius, the cylindrical section ( 4 ) with larger radius rests against a cylindrical wall ( 13 ) of the outer cylindrical body ( 1 ), which wall ( 13 ) is matched to said larger radius, with a dish-shaped space being formed between the cylindrical section ( 3 ) with smaller radius and the wall ( 13 ) of the outer body ( 1 ), said dish-shaped space containing the two chambers ( 25 , 26 ), the wall of the outer body ( 1 ) parallel to the axis comprises said contraction ( 16 , 30 ) whose vertex region delimits the throttle gap ( 17 ) with the cylindrical section ( 3 ) with the smaller radius, and end regions of the cylindrical section ( 3 ) with smaller radius of the inner body ( 2 ) are sealed in relation to the outer body ( 1 ).
