Fluid-filled cylindrical elastic mount having means for improved durability of elastic body

摘要

A fluid-filled cylindrical elastic mount for flexible coupling of two members, including an elastic body which is interposed between an inner and an outer sleeve for elastic connection therebetween and which has a pressure-receiving chamber filled with a non-compressible fluid and communicating with an equilibrium chamber through a restricted passage. The elastic body has a portion defining a void formed therethrough in an axial direction of the elastic mount. The void is positioned between the pressure-receiving chamber and one of the inner and outer sleeves, as viewed in a load-receiving direction in which the elastic body is compressed when the elastic mount is attached to the two members.
