Mounting device of power unit

Abstract

Abstract PURPOSE:To enable the vibro-isolating and damping action against high and low frequency vibration to be displayed in the suitable timing as necessary, by providing the first and the second orifices in a separtor member to be selectively opened and closed by a control signal from the outside. CONSTITUTION:The first orifice 48 of small sectional area and the second orifice 50 of large sectional area are provided in a separator member 20 and a core member 42. Then an actuator member 52, which can open and close the second orifice 50, is provided in the upper of the core member 42, and the core member 42 provides an electromagnet 46 excited by a signal from a control device 66. In this way, the vibro-isolating action for high frequency vibration and the damping action against low frequency vibration can be displayed in the suitable timing as necessary by opening and closing the second orifice 50 by the control signal from the outside so as to enable circulative flow resistance to be effectively changed.
