Fluid-filled resilient engine mount

A fluid-filled resilient engine mount comprising:

• an inner sleeve;
• an outer sleeve located radially outwardly of said inner sleeve and having an axis parallel to that of said inner sleeve;
• a generally annular resilient member interposed between said inner and outer sleeves, said resilient member having a plurality of voids which are spaced from each other in a circumferential direction of said resilient member and are open in an outer surface of said resilient member, said outer sleeve closing said voids and thereby cooperating with said resilient member to define a plurality of fluid chambers corresponding to said voids, said fluid chambers being filled with a fluid;
• a metallic orifice block press-fitted on the outer surfaces of said inner sleeve, and having at least one orifice through which said plurality of fluid chambers communicate with each other;
• and
• a stopper block of an elastic material positioned adjacent to an opening of each of said plurality of voids and fixed relative to said outer sleeve and said resilient member, said stopper block having an abutting portion which protrudes in the corresponding fluid chamber toward said orifice block, said abutting portion being spaced from said orifice block;
• said metallic orifice block having a plurality of surfaces each of which includes a portion on which said abutting portion of said stopper block is abuttable to thereby prevent an excessive amount of elastic deformation of said resilient member, and another portion in which said at least one orifice is open, said another portion being free of abutment of said abutting portion.

• a generally annular resilient member interposed between said inner and outer sleeves, said resilient member having a plurality of voids which are spaced from each other in a circumferential direction of said resilient member and are open in an outer surface of said resilient member, said resilient member further having a pair of seats formed adjacent to opposite edges of an opening of each of said voids which are parallel to the axis of said inner sleeve, said outer sleeve closing said voids;
• a metallic member fitted on the outer surface of said inner sleeve, and cooperating with said outer sleeve and said resilient member to define a plurality of fluid chambers corresponding to said voids, such that said metallic member defines a bottom of each of said fluid chambers, said fluid chambers being filled with a fluid;
• means for defining at least one orifice through which said plurality of fluid chambers communicate with each other;
• and
• a stopper block of an elastic material positioned adjacent to said opening of each said void, said stopper block having an arcuate outer surface in pressed contact with an inner surface of said outer sleeve, and a pair of end faces at opposite ends of said arcuate outer surface, said pair of end faces being held in contact with said pair of seats of said resilient member, said stopper block further having an abutting portion which protrudes in the corresponding fluid chamber toward said inner sleeve, said abutting portion being spaced from said metallic member, and abuttable on said metallic member, thereby preventing an excessive amount of elastic deformation of said resilient member. deformation said resilient member.
