摘要： A fluid filled vibration damping device wherein a first and second mounting member are connected by a main rubber elastic body, a pressure receiving chamber partially formed by the rubber elastic body and an equilibrium chamber partially formed by a flexible film are formed on either side of a partition member supported by the second mounting member, an orifice passage is formed for permitting a fluid communication between the pressure receiving chamber and equilibrium chamber communicate both having a non-compressible fluid; and a movable rubber plate is housed in a housing space so that minute pressure fluctuations in the pressure receiving chamber can be absorbed by the equilibrium chamber by means of the movable rubber plate. The movable rubber plate includes at least partially a corrugated part expanding generally a form of a corrugated panel by means of continuous depressions and protrusions.

摘要： A vibration damping device including: a main rubber elastic body connecting a first and a second mounting members; a fluid-filled unit having a tubular housing closed off by a rubber elastic wall and a flexible film for providing therein a fluid chamber filled with a non-compressible fluid, and a partition member positioned within the fluid chamber to form on a first side thereof a primary fluid chamber partly defined by the rubber elastic wall, and on the other side thereof a secondary fluid chamber partially defined by the flexible film, with these chambers communicating through an orifice passage; and a rigid piston member. Upon input of vibration across the first and second mounting members, pressure fluctuations is exerted on the primary fluid chamber through elastic deformation of the rubber elastic wall of the fluid-filled unit induced through pushing by the contacting member via the piston member.

摘要： A vibration damping device wherein a first stopper portion is disposed at an opening of a tubular portion of a bracket member to jut out over the opening; a second stopper portion of portal shape is disposed bridging the first opening of the tubular portion at a location axially outward from a first stopper portion; a main unit is inserted into another opening of the tubular portion; a separate stopper is juxtaposed against a first mounting member, incorporated as part of a stopper mechanism for limiting a relative displacement between the first and second mounting members in bound and rebound directions through contact with the first and second stopper portions; mounting holes perforate the first mounting member and the separate stopper; and a fixing bolt for fixing the first mounting member and the separate stopper is fixed at a location away from the mounting holes. A method of manufacturing the same is also disclosed.

摘要： A fluid filled type vibration damping device including a fluid filled unit having a fluid chamber sealed therein, a main rubber elastic body being a separate component from the fluid filled unit, a first mounting member affixed to the main rubber elastic body at a center section of a first end thereof. The fluid filled unit is positioned next to the other end of the main rubber elastic body with an elastic rubber wall thereof juxtaposed against the end face of the main rubber elastic body. A second mounting member is formed by including a tubular housing of the fluid filled unit with the tubular housing fastened to an outside peripheral face of the main rubber elastic body. An outside air communication passage is formed at an outside peripheral section between the juxtaposed elastic rubber wall of the fluid filled unit and the end face of the main rubber elastic body.
