Total Claims: 7
Claim 1
Independent Claim
184 words
A rubber vibration insulating device, comprising: a boss member, a cylindrical body; an annular elastic member interposed between and sealingly interconnecting said boss member and one end of said cylindrical body; a plate member sealingly secured to an opposite end of said cylindrical body whereby a sealed chamber having a variable volume is defined and surrounded hermetically by the foregoing elements, said sealed chamber housing internally thereof a capsule comprising an external shell which consists of a rubber plate and a plate body joined together and a diaphragm transversely provided inside said shell thereby forming an air sub-chamber surrounded by said diaphragm and said plate body and a liquid sub-chamber surrounded by said diaphragm and said rubber plate, said rubber plate having means defining an orifice extending through said rubber plate for providing communication between said liquid sub-chamber and said sealed chamber, said sealed chamber being filled with a liquid so that said liquid passes through said orifice between said sealed chamber and said liquid sub-chamber, said capsule being wholly surrounded by said liquid in said sealed chamber and floatingly suspended in said liquid.
Claim 2
Dependent Claim
184 words
A rubber vibration insulating device, comprising: a boss member, a cylindrical body; an annular elastic member interposed between and sealingly interconnecting said boss member and one end of said cylindrical body; a plate member sealingly secured to an opposite end of said cylindrical body whereby a sealed chamber having a variable volume is defined and surrounded hermetically by the foregoing elements, said sealed chamber housing internally thereof a capsule comprising an external shell which consists of a rubber plate and a plate body joined together and a diaphragm transversely provided inside said shell thereby forming an air sub-chamber surrounded by said diaphragm and said plate body and a liquid sub-chamber surrounded by said diaphragm and said rubber plate, said rubber plate having means defining an orifice extending through said rubber plate for providing communication between said liquid sub-chamber and said sealed chamber, said sealed chamber being filled with a liquid so that said liquid passes through said orifice between said sealed chamber and said liquid sub-chamber, said capsule being wholly surrounded by said liquid in said sealed chamber and floatingly suspended in said liquid.
Claim 3
Dependent Claim
51 words
A rubber vibration insulating device as claimed in claim 1, wherein said rubber plate constituting a part of said shell of said capsule is provided on both sides of an inner portion thereof with plural spaced recesses, opposed bottoms of said recesses defining a thin film portion in said rubber plate.
Claim 4
Dependent Claim
55 words
A rubber vibration insulating device as claimed in claim 1, wherein said rubber plate constituting a part of said shell of said capsule includes a pair of porous plates and a rubber disc interposed between said porous plates so as to be floatingly movable up to a definite deflection magnitude in its axial thickness direction.
Claim 5
Dependent Claim
27 words
A rubber vibration insulating device as claimed in claim 1, wherein said annular elastic member incorporates in its middle portion a mass damper in the cylinder shape.
Claim 6
Dependent Claim
26 words
A rubber vibration insulating device as claimed in claim 1, wherein the interior wall of said sealed chamber is formed with a plurality of rubber projections.
Claim 7
Dependent Claim
25 words
A rubber vibration insulating device as claimed in claim 1, wherein an external wall of said capsule is formed with a plurality of rubber projections.
