Abstract
A liquid-sealed mounting device that can suitably attenuate and cut off various vibrations of an engine, reduce the number of parts and components necessary, and reduce the energy consumed by the actuator by lowering the operation ratio thereof. The liquid-sealed mounting device includes an upper liquid chamber and a lower liquid chamber, both of which are sealed an have liquid contained therein. The chambers communicate with each other via two orifices provided therebetween. One of the orifices is normally open, while the second orifice may be opened and closed by means of a valve body. An electromagnetic actuator drives the valve body to the open or closed position thereof, and a vibration absorber vibrated and driven by the electromagnetic actuator is provided in the upper liquid chamber. The valve body and the vibration absorber may be used together as a unitary member. A valve stem supports the valve body/vibration absorber and a spring member energizes the valve body/vibration absorber directions toward the opened and closed positions.
