Abstract:
A fluid-filled elastic mount of suspension type, comprising:a first mounting member; a second mounting member including a cylindrical portion extending in a vertical direction and having a vertically lower open-end portion in which said first mounting member is inserted and disposed; a generally tapered elastic body interposed between said first and second mounting members so as to extend from said vertically lower open-end portion of said cylindrical portion of said second mounting member into an inside of said cylindrical portion for fluid-tightly closing said vertically lower open-end portion of said cylindrical portion of said second mounting member and for elastically connecting said first mounting member and said cylindrical portion of said second mounting member with each other; a flexible layer fluid-tightly closing a vertically upper open-end portion of said cylindrical portion of said second mounting member for forming a fluid chamber defined between said generally tapered elastic body and said flexible layer and filled with a non-compressible fluid; a partition member disposed within said fluid chamber so as to extend in a generally radial direction perpendicular to an axial direction of said cylindrical portion, and fixedly supported at an peripheral portion thereof by said second mounting member, for fluid-tightly dividing said fluid chamber into a pressure-receiving chamber partially defined by said generally tapered elastic body and an equilibrium chamber partially defined by said flexible layer; an orifice passage for permitting a fluid communication between said pressure-receiving chamber and said equilibrium chamber; and a restricting projection formed of an elastic body and bonded to said partition member so as to protrude into said pressure-receiving chamber and located in an intermediate portion between said generally tapered elastic body and said cylindrical portion of said second mounting member opposed to said generally tapered elastic body in said generally radial direction, for restricting a generally annular region of said intermediate portion, wherein said restricting projection is arranged to be spaced away from both of said generally tapered elastic body and said cylindrical portion of the second mounting member.
