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 vibration controller includes a map controller, an adaptive controller, a set-up frequency judge/switcher, and an actuator. The map controller includes a data map storage for storing data on control signals determined in advance for a vibration insulator, and a signal generator for selecting one of the data, depending on a frequency of a cyclically pulsating signal emitted from a vibration generating source of a vehicle, from the data map storage and generating a control signal. The adaptive controller generates the control signal with respect to the cyclically pulsating signal using an adaptive control method. The set-up frequency judge/switcher switches from the map controller to the adaptive controller or vice versa based on the frequency of the cyclically pulsating signal. The actuator actuates an actuator of the vibration insulator based on the control signal generated by the map controller or the adaptive controller, whereby inhibiting the vehicle from vibrating.
