摘要： A vibration damping device wherein a stopper rubber disposed between opposing faces of a first mounting member and the retainer member so as to project from one of the opposing faces to the other. When the first and second mounting members undergoes relative displacement axially towards each other, a shock produced at a time when an abutting face of the first mounting member comes into contact with the open end face, i.e., an abutting face of the retainer member absorbed by the stopper rubber coming into contact with the other one of the opposing faces until the first mounting member comes into contact with the open end face of the retainer member. A receiving space is disposed between the opposing faces of the first mounting member and the retainer member so that the stopper rubber is accommodated in an elastically compressive-deformed state within the receiving space when the abutting faces contact together.

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.

摘要： A fluid-filled elastic mount including first and second support members and an elastic body interposed between these members for elastic connection thereof. The elastic mount has a pressure-receiving chamber partially defined by the elastic body, first and second equilibrium chambers defined by first and second flexible diaphragms and communicating with the pressure-receiving chamber through first and second orifice passages, respectively. The second orifice passage has a higher ratio of the cross sectional area to the length than the first orifice passage. The present elastic mount further includes a pressure control device for selectively applying a vacuum pressure to a vacuum-receiving chamber which lies behind the second equilibrium chamber via the second diaphragm, to thereby restrict elastic deformation of the second diaphragm. A rigid restriction member is secured to a part of the second diaphragm which is opposed to an opening of an air passage through which the vacuum pressure is applied to the vacuum-receiving chamber.

摘要： A fluid-filled elastic mount including a first and a second support member which are spaced apart from each other in a load-receiving direction, an elastic body for elastically connecting these support members, and a partition structure supported by the second structure. The elastic mount has a pressure-receiving chamber partially defined by the elastic body, and a first and a second equilibrium chamber partically defined by respective first and second flexible diaphragms. The elastic mount further has a member which cooperates with the first diaphragm to define a first air chamber separated from the first equilibrium chamber by the diaphragm, and a pressure control device for applying a selected one of two different pressures to the first diaphragm or the above-described member, so as to selectively permit and inhibit elastic deformation of the first flexible diaphragm. A non-compressible fluid in the mount flows between the pressure-receiving and the first equilibrium chambers through a first orifice passage, and between the pressure-receiving and the second equilibrium chambers through a second orifice passage as well as the first orifice passage.

摘要： An apparatus for performing a function by using a fluid, which includes: a mass of a fluid whose viscosity varies with an electric current applied thereto; a pair of electrodes which are disposed so as to apply the electric current to the mass of the fluid; a device for controlling a voltage to be applied between the pair of electrodes to substantially change the viscosity of the mass of the fluid; and electrically resistive layers each having a predetermined electrical resistance value and covering each of the pair of electrodes, each of the resistive layers consisting of an insulating material having a low electrical conductivity. Thus, the present apparatus is capable of restricting an increase in an electrical current consumed by the mass of the fluid, when an electrical resistance value of the mass of the fluid is lowered due to a rise in an operating temperature of the mass of the fluid.
