ABSTRACT:
A device for dampening the movement of a pivotally supported structural part, for example, a flap or closure within an automobile, comprises a pivot arm attached to the structural part, and a rack operatively connected to the pivot arm. A housing is rotatably supported upon a support surface or member, and a rotor is rotatably disposed within the housing along with a viscous fluid which tends to dampen rotary motion of the rotor. The rotor also comprises a pinion which is enmeshed with the rack, and the housing comprises a pair of guides for confining movement of the rack in a translational or rectilinear mode while maintaining the rack enmeshed with the rotor pinion. Consequently, when the flap or closure is either opened or closed, the flap or closure is moved in a dampened mode due to the movement of the pivot arm and the rack relative to the dampened rotor pinion. As a result of the rotary mounting of the housing, and the provision of the rack guides, the rack undergoes both rotary and translational movements while being maintained enmeshed with the rotor pinion.
