摘要： Disclosed is a pneumatically operated fluid-filled active vibration-damping device including: a primary fluid chamber partially defined by an elastic body and filled with a non-compressible fluid; a movable member being elastically displaceable and partially defining the primary fluid chamber its one side; a working air chamber disposed on the other side of the movable member; and an air reservoir directly extending from the working air chamber and fluid-tightly closed at its protruding end portion. A fluid pressure variation in the primary fluid chamber is induced by an elastic deformation of the elastic body while being actively controlled by transmitting an air pressure variation applied to the working air chamber from an external area to the primary fluid chamber via the movable member. A vibration-damping apparatus using the vibration-damping device is also disclosed.

摘要： Disclosed is a fluid-filled active vibration damping device including: an elastic body; a primary fluid chamber partially defined by the elastic body; a movable member partially defining the primary fluid chamber on one side and a working air chamber on the other side; and a vacuum pump including an air intake port and an exhaust port, which are connectable to the working chamber via a valve mechanism. A fluid pressure variation in the primary fluid chamber can be actively controlled by transmitting an air pressure variation in the working air chamber to the primary fluid chamber via the movable member. A switching operation of the valve mechanism selectively applies a negative pressure generated in the air intake port and a positive pressure generated in the exhaust port to the working air chamber in order to generate the air pressure variation in the working air chamber.

摘要： A reference pulse signal P is produced which is synchronized in frequency with a pulse signal S derived from a vibration source and has a predetermined duty ratio. Then, a control signal C is produced by providing at least one or more off intervals &agr;, &bgr; . . . at a random timing and random width predetermined for the reference pulse signal P to have the control amplitude correlated with the amplitude of the vibrations at the vibration source. This control signal C is used for controlling the switching action of the electromagnetic valve to have a desired level of pressure change in an air chamber 35 of a pneumatic vibrator which in turn develops a vibrating force on a mass member 20. The vibrations of the mass member can thus offset the vibrations of the chassis of a vehicle. Also, an electromagnetic vibrator can produce a similar control signal for eliminating the vibrations of the chassis.
