ABSTRACT:
Relative motion between movable parts is damped by way of a hydraulic damper having radial vanes in a hydraulic damping fluid filled working chamber and dividing the chamber into subchambers which respectively increase and decrease in volume in response to torsional movements of the vanes in the working chamber during relative rotation of subassemblies of the damper. Damping is effected by controlled displacement of the hydraulic damping fluid between the subchambers through restricted orifices across an edge of the vanes during torsional movements of the vanes responsive to relative motion of the parts to be damped. Damping may be provided in either direction of rotation. Another level or no damping may be provided in the opposite direction of rotation. Substantially equal damping may be effected in both directions of rotation. A range of adjustments of the restricted orifices is provided for. The damper may be equipped with an overload pressure relief device.
