Abstract

A fluid sealed type vibration insulating device provided with an actuator for generating an active supporting force. The vibration insulating support device includes a main fluid chamber defined by a cylindrical elastic support and a movable plate connected to a non-linear type plate spring. The main fluid chamber is fluidly communicated with a variable-volume auxiliary fluid chamber through an orifice. The actuator moves the movable plate to change a dynamic spring characteristic and a damping characteristic of a fluid resonance system constituted by a mass of fluid in the orifice and a spring of an expanding direction of the elastic support and the plate spring. Therefore, a required output of the actuator is suppressed.
