ABSTRACT:
The actuator is disposed in the damper piston rod and includes a solenoid with a reciprocating plunger, a motion converting mechanism which converts solenoid reciprocation to rotation of an input driver, an intermediate driver rotatable with the input driver, a rotatable output driver connected to a valve adjusting rotor in the damper piston, and a torsion spring between the intermediate and output drivers. The spring holds the output driver in a following relation to the intermediate driver so that when pressure spikes immobilize the valve rotor and output driver, the input driver can continue to rotate to a control position. When rotor mobility returns, the spring automatically advances the output driver and valve rotor to the same position which would have been achieved had the rotor not been temporarily immobilized.
