Fluid-filled cylindrical elastic mount having rigid protrusion axially defining fluid chamber

A fluid-filled cylindrical elastic mount for flexibily connecting two members, comprising:

• an inner sleeve fixed to ne of the two members;
• an outer sleeve disposed radially outwardly of said inner sleeve and connected to the other of the two members;
• at least one elastic body disposed between the inner and outer sleeves for flexible connection therebetween, said at least one elastic body at least partially defining at least one fluid chamber filled with a non-compressible fluid and extending a circumferential direction of the mount between the inner and outer sleeves;
• a wing member fixed to one of the inner and outer sleeves so as to protrude from said one sleeve toward the other of said inner and outer sleeves, and so as to be displaceable together with said one sleeve in an axial direction of the mount when the mount receives a vibrational load in said axial direction, said wing member being disposed at an axially intermediate portion of each of said at least one fluid chamber such that said each fluid chamber is divided into two sections located on axially opposite sides of said wing member, sic wing member having a radial end face which cooperates with an inner wall of said each fluid chamber to define therebetween a restricted fluid passage having a predetermined radial dimension and communicating with said two sections;
• and
• at least one rigid protrusion protruding radially from the other of said inner and outer sleeves, by a radial distance which is larger than said predetermined radial dimension of said restricted fluid passage, said at least one rigid protrusion defining at least one of axially opposite ends of tat least a radial portion of said at least one fluid chamber, said radial portion being aligned with said restricted fluid passage in a radial direction of the mount.
