ABSTRACT:
The fluid circuitry connecting variable volume chambers of the semiactive damper includes valve assemblies which collectively effect mechanical implementation of a preselected damper control policy that is based in part upon changes in the sign of the absolute velocity of a supported member of the system of which the damper forms a part. One of the valve assemblies has an inertial body which is connected to a movable system member but which remains substantially stationary during system operation. The inertial body and a valve member of the assembly are interconnected by a linkage which in one embodiment includes a frictional type connector, and which in another embodiment includes a dashpot.
