摘要： A fluid-filled vibration damping device having an elastic body connecting two mutually spaced-apart mounting members, a fluid chamber filled with a non-compressible fluid, and a movable member which partially defines the fluid chamber and which is oscillated to control a pressure of the fluid in the fluid chamber, for regulating damping characteristics of the device. The movable member partially defines a working air-chamber on one of opposite sides thereof which is remote form the fluid chamber, and is oscillated by a periodic change of an air pressure which is applied to the working air-chamber. A restoring member is disposed on at least one of opposite sides of the movable member for elastically supporting the movable member, so that an elastic force of the restoring member acts on the movable member to restore the movable member to an original position thereof during oscillation thereof.

摘要： An elastic mount wherein a first and a second support member are spaced apart from each other and elastically connected to each other by an elastic body, wherein the second support member has a cylindrical fixing portion having a larger diameter than the first support member, and a cylindrical bracket member is press-fitted on the fixing portion of the second support member such that the cylindrical bracket member encloses the first support member. The bracket member includes an axial end portion provided with an integrally formed abutting part opposed to the first support member in an axial direction of the bracket member. A buffer member interposed between the first support member and the abutting part cooperates with the first support member and the abutting part to constitute a first stop mechanism for limiting an amount of relative displacement of the first and second support members away from each other, by abutting contact of the first support member and the abutting part with each other through the first buffer member. Also disclosed is a method of producing the present elastic mount.

These chambers are filled with a non-compressible fluid. The partition member has a cylindrical positioning shoulder, while the closure member has a cylindrical wall portion which is press-fitted onto the positioning shoulder of the partition member, so that the partition and closure member are positioned relative to each other in their diametric direction. The partition member also has an axial protrusion extending in its circumferential direction and diametrically opposed to the cylindrical wall portion of the closure member with a radial spacing therebetween to define an annular passage, and a partition wall disposed at a circumferential portion of the annular passage to fluid-tightly intercept the annular passage. The annular passage is held in fluid communication with the pressure-receiving chamber through a first communication hole formed on one side of the partition wall and with the equilibrium chamber through a second communication hole formed on the other side of the partition wall, to serve as an orifice passage.

摘要： A fluid-filled cylindrical elastic mount including an inner sleeve, an outer sleeve disposed radially outwardly of the inner sleeve with a predetermined radial spacing therebetween, and a generally annular elastic body interposed between the two sleeves for elastic connection therebetween. The elastic body at least partially defines an annular fluid chamber formed between the two sleeves and extending over the entire circumference of the mount. The fluid chamber has a substantially constant cross sectional area over the entire circumference thereof, and is filled with a non-compressible fluid having a kinematic viscosity of not higher than 100 centistokes. The elastic mount further includes an annular movable member accommodated in the fluid chamber, such that the movable member can be radially displaced relative to the inner and outer sleeves. The movable member and the fluid in the fluid chamber cooperate to provide a restricted resonance portion through which the non-compressible fluid is forced to flow with a resistance upon application of a vibrational load between the two sleeves.
