ABSTRACT:
An elastically damping device for the suspension of an engine of a vehicle, by which the engine vibrations are prevented from being transmitted to the body of the vehicle, is disclosed. The damping device is provided with a first fluid chamber and a second fluid chamber, each of which is defined by an elastically deformable wall. The fluid chambers are separated from each other by means of a partition plate, of which at least one portion is formed into a movable plate being movable in such a direction as to lower the increased inner pressure of the fluid chambers, and which has a restricted passageway for communicating the fluid chambers. The damping device of the present invention further comprises two stopper portions for stopping the movement of the movable plate and an electromagnetic coil for operating one or two stopper portions so as to control the movable distance of the movable plate in accordance with the driving condition of the vehicle. The electromagnetic coil operates the stopper portions to make the movable distance of the movable plate small at both of an engine starting time and a vehicle running time and to make the movable distance of the movable plate large at an engine idling time.
