PROBLEM TO BE SOLVED: To realize the flow control means of a resonant orifice in a simple structure. SOLUTION: An idle orifice 38 connecting a primary fluid chamber and a sub-fluid chamber 9 is arranged on a partition member 7 partitioning the fluid chamber of a fluid-filled engine mount, and the flow rate of fluid is controlled by a flow rate controlling means 40. The flow rate controlling means 40 is arranged on the outlet of the idle orifice 38; and a coil 42, an elastic membrane 43, a third diaphragm 44, and an adjusting chamber 45 are provided. Magnetic viscous fluid 46 is enclosed within the adjusting chamber 45, and viscosity of the magnetic viscous fluid 46 is changed when magnetic force of the coil 42 is controlled. The flow rate of fluid of the idle orifice 38 is controlled so as to change an elastic changing amount of the elastic membrane 43. COPYRIGHT: (C)2005,JPO&NCIPI |
