摘要： A fluid filled engine mount including: a pressure-receiving chamber and an equilibrium chamber connected via an orifice passage tuned to a frequency band of engine idling vibrations; an orifice control member operable by means of negative pressure exerted from an external space so as to restrict flow of the fluid through the orifice passage when an absolute value of the exerted negative pressure is greater than a predetermined value; and a negative pressure conduit of direct connection type, adapted to always introduce negative pressure available from an air intake port of an internal combustion engine to the orifice control member.

摘要： A fluid filled engine mount including: a pressure-receiving chamber and an equilibrium chamber connected via a first orifice passage tuned to excite resonance of fluid flowing therethrough to engine shakes; a partition rubber plate partially defining a pressure receiving chamber and tuned to perform absorption of a fluid pressure fluctuation in the pressure-receiving chamber to booming noises; an oscillating chamber connected to the pressure receiving chamber via a second orifice passage tuned to excite resonance of the fluid flowing therethrough to idling vibrations; an oscillating rubber elastic plate having an expansion spring smaller than that of the partition rubber plate and defining the oscillating chamber; a working air chamber applied with air pressure fluctuation with a frequency corresponding to the idling vibration during idling, and to make the working air chamber atmospheric pressure during running.

摘要： Disclosed is a pneumatically operated fluid-filled active vibration-damping device including: a primary fluid chamber partially defined by an elastic body and filled with a non-compressible fluid; a movable member being elastically displaceable and partially defining the primary fluid chamber its one side; a working air chamber disposed on the other side of the movable member; and an air reservoir directly extending from the working air chamber and fluid-tightly closed at its protruding end portion. A fluid pressure variation in the primary fluid chamber is induced by an elastic deformation of the elastic body while being actively controlled by transmitting an air pressure variation applied to the working air chamber from an external area to the primary fluid chamber via the movable member. A vibration-damping apparatus using the vibration-damping device is also disclosed.

摘要： Disclosed is a fluid-filled vibration-damping device and a method of manufacturing the same, wherein an elastic body connecting a first and second mounting members partially defines a fluid-filled zone filled with non-compressible fluid, and a sealing part of the fluid-filled zone is formed by forcedly fitting an annular fixing projection formed on one of an inner circumferential surface of a first sealing member or an outer circumferential surface of a second mounting member into an annular fixing recess formed onto the other. Drain passages are formed at an interface between the annular fixing recess and projection to expose a floor of the annular fixing recess to an outside. Compressed air is blown into one of the drain passages so as to blow away or forcedly discharge the non-compressible fluid remained on the floor of the annular fixing recess to the outside through another drain passage.
