摘要： A fluid filled type vibration damping device includes: a main rubber elastic body elastically connecting first and second mounting members; a partition member supported by the second mounting member; a pressure-receiving chamber partially defined by the elastic body and having a non-compressible fluid sealed therein; an equilibrium chamber partially defined by a flexible film and having the non-compressible fluid therein. The chambers are formed to either side of the partition member and an orifice passage permits a fluid communication between the two chambers. A short-circuit passage is formed so that the pressure-receiving and equilibrium chambers are able to be short-circuited through the short-circuit passage. A valve is used for switching the short-circuit passage, and a metal spring is used for holding the valve in a closed state at a predetermined initial level of elastic deformation.

摘要： A vibration controller includes a data map storage, a detector, a determiner, a signal generator, and an actuator. The data map storage stores amplitude and/or phase data with respect to torque values of a vehicle engine as a data map in advance. The detector detects actual torque values of the vehicle engine. The determiner determines one of the amplitude and/or phase data with respect to one of the actual torque values based on the data map. The signal generator generates a control signal based on cyclic pulsating signals emitted from the vehicle engine, and updates the amplitude and/or phase of the control signal based on the one of the determined amplitude and/or phase data. The actuator actuates an electromagnetic actuator of an active vibration insulator based on the updated control signal, whereby inhibiting vibrations of the vehicle engine from transmitting by means of vibrating forces exerted by the electromagnetic actuator.

摘要： A fluid-filled vibration damping device wherein two mutually spaced-apart mounting members are connected by an elastic body, which cooperate with an elastic wall member to partially define a pressure-receiving chamber, and a flexible diaphragm partially defines an equilibrium chamber on one side and a working air chamber on the other side. These chambers are filled with the non-compressible fluid and held in fluid communication with each other through the orifice passage. A negative pressure-regulating device applies different negative pressure to the working air chamber depending upon frequencies of vibration to be damped, so that a spring constant of the elastic wall member is changed corresponding to the vibration to be damped, thereby controlling a damping characteristics of the damping device.
