    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 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 fluid-filled type vibration-damping device having an elastic rubber film partially defining a primary fluid chamber at one surface and partially defining a pressure action chamber. The pressure action chamber varies its pressure under control so that the elastic rubber film changes its elasticity to change damping characteristics of the device. To give sufficient recovery force for the elastic rubber film, the elastic rubber film includes a plurality of thick reinforcing ribs circumferentially spaced apart from one another and extending in a radial direction from an outside peripheral edge over a length not reaching a center so that areas situated between pairs of adjacent reinforcing ribs constitutes thin portions formed by a thin rubber elastic body, while the center portion of the elastic rubber film situated between distal ends constitutes a bowed center portion thinner than the reinforcing ribs and convex towards the pressure action chamber.

    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.

    摘要: A fluid-filled vibration damping device including: an elastic body connecting a first and a second mounting member, defining a pressure receiving chamber undergoing pressure fluctuation during input of vibration; an equilibrium chamber defined by a flexible layer for permitting its volume change; an orifice passage connecting the pressure receiving chamber and equilibrium chamber; a movable member; and a short passage for connecting two chambers with a length smaller than that of the orifice passage. When pressure in the pressure-receiving chamber increases, the movable member is displaced or deformed toward to close the equilibrium-chamber-side opening of the short passage to have the short passage substantially closed, while when pressure in the pressure-receiving chamber decreases, the movable member is displaced or deformed to have the short passage operative.

    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.
