Abstract
A pivot-action damper which for example dampens the impact effect of the closing movement of doors, furniture doors or flaps displays excellent braking force or damping force, even over small angular regions as a result of an outer cylindrical body which encompasses an inner body which is pivotable in relation to said outer cylindrical body. Between the two bodies there are two chambers, separated from each other by a gap or a throttle position, with said chambers containing a liquid. This liquid is displaced from one chamber to the other as a result of the rotation of the two bodies in relation to each other.

- 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
