A hydraulic mount 10 provides active control of dip rate performance through use of an orifice track 24 connecting a primary pumping chamber 14 of the mount 10 to a secondary fluid chamber 18 having a movable wall 20, and an actuator 26 for regulating pressure applied to the movable wall 20 for controlling movement of the movable wall 20. With little or no pressure applied to the movable wall 20, the mount 10 provides significant isolation and very little damping in a predetermined and designed frequency range. As pressure is applied to the movable wall 20 , the stiffness of the mount 10 is increased significantly, to thereby provide substantial damping.
