<p>A damping arrangement for a hinge comprises a spindle 10 having a cam surface 22 that engages a follower surface 28 on a damping piston 25 located in a housing 1. The cam surface is configured to urge the damping piston away from the spindle axis as the hinge moves to a closed position. The flow of hydraulic fluid through a circuit, which may be controlled by at least one adjustable valve, damps the closing movement. The configuration of the cam surface and follower surface are selected so that displacement of the damping piston caused by incremental angular rotation of the spindle is at a maximum value as the closed position is approached. A closing piston may be included to apply a closing force to the hinge. The profile of the cam surface may have a maximum radial dimension at a location engaging the cam follower when the hinge is closed.</p> |
