Abstract
The expansion/contraction timing of an actuator chamber is varied in accordance with the sensed engine vibration in a manner as to compensate for the frequency dependent change in pressure transmission characteristics between the chamber of the actuator and the chamber of an engine suspension insulator. This is done by sensing the engine vibration frequency or a parameter which varies in accordance with same (e.g. RPM) and suitably delaying a solenoid or similar electric motor energization signal in accordance with the frequency of the vibration.
