<p>A hydraulic damper has a rotor (56) on a piston of the damper rotatable through a plurality of control positions to vary the damping capability of the damper and subject to temporary rotary immobility by pressure spikes in the damper, an actuator (60) within the piston rod (30) of the damper including a solenoid (82), an input driver (122) rotatable through a plurality of positions corresponding to the control positions of the rotor, a pawl (16) and lever system operable by a plunger (86) to rotate the input driver in stepwise fashion, an intermediate driver (138) rotatable with the input driver, an output driver (152) connected to and rotatable with the rotor, an abutment (142) on the intermediate driver, an arm on the output driver engageable on the abutment, and a torsion spring (177) connected between the intermediate and output drivers and operative to normally hold the arm against the abutment so that the intermediate and output drivers rotate as a unit, and further operative to allow the intermediate driver to rotate relative to the output driver when the rotor is immobilized and then, when rotor mobility returns, to rotate the rotor and the output driver until the arm engages the abutment.</p> |
