摘要： A fluid filled type vibration damping device includes a first mounting member, a second mounting member, a main rubber elastic body, a flexible film, a partition member, a valve, a coil, a control-signals-generating circuit and a power amplifier circuit. The valve enables to switch the second orifice passage between an open state and a closed state. The second orifice passage communicates the pressure-receiving chamber and the equilibrium chamber with each other. The switch of the valve is performed by an electromagnetic force occurring by an electrical connection of the coil. Furthermore the control-signals-generating circuit is formed and disposed separately from the coil. The control-signals-generating circuit produces state switching control signals of the valve. Moreover the power amplifier circuit which supplies an electric-current to the coil by amplifying the state switching control signals, constitutes an actuator unit attached integrally to the coil, and is disposed separately from the control-signals-generating circuit.

摘要： A Fluid-filled type vibration damping device, which is configured to be free from the necessity of supplying a continuous application of electricity to a coil so as to maintain a movable valve body in either an opened state or a closed state, is provided. The device includes a cam mechanism, which transmits a rotational drive force of a motor to the movable valve body in the form of a reciprocating drive force. In the device, a first rotation angle switch is connected to a first control switch in series relative to a motor coil, and a second rotation angle switch is connected to a second control switch in parallel relative to the first switch. The first rotation angle switch is turned on in a state of a first angular range θ1, and the second rotation angle switch is turned on in a third angular range θ3. When the first control switch and the second control switch receive the same control signal, they are brought into respective inverted ON/OFF states. The first angular range θ1 includes a fourth angular range θ4, which has an angle different from at least a third angular range θ3. The third angular range θ3 includes a second angular range θ2, which has an angle different from at least the first angular range θ1.

摘要： A fluid-filled type vibration-damping device having a movable rubber plate housed within a partition member partitioning a pressure-receiving chamber and an equilibrium chamber from each other. The movable rubber plate is moved owing to the pressure difference between the two chambers. The movable rubber plate comprises the movable rubber plate formed of a generally disk shaped rubber elastic body having formed thereon in alternating fashion concave grooves and convex ribs each extending in a circumferential direction about a same center axis, the convex ribs have tapered cross section gradually narrowing in width towards an distal end thereof, and the concave grooves and convex ribs are disposed at the same locations in a diametrical direction on either face of the movable rubber plate so that the thickness of the movable rubber plate is varied in the circumferential direction.
