Abstract
Abstract A mounting mechanism which directly connects a compressor of an automotive air conditioning system to an automobile engine. A flange portion projects from an outer peripheral surface of the compressor and bolt-nut mechanisms connect the flange portion of the compressor to the automobile engine. The flange portion has at least one first hole having a vibration absorbing coupling mechanism disposed therein. The coupling mechanism includes at least one cylindrical bushing which is fixedly disposed within the first hole and includes an outer cylinder, an inner cylinder and a vibroisolating rubber member which is fixedly disposed between the outer and inner cylinders by adhesion. At least two attaching members having cylindrical portions with holes for receiving a bolt-nut mechanism, are provided with bars which are securedly inserted into the bushing inner cylinder.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
157 words
In a mounting mechanism for directly mounting an automotive air conditioning compressor on an automobile engine including a flange portion projecting from an outer peripheral surface of the compressor and bolt-nut mechanisms connecting the flange portion of the compressor to the automobile engine, the improvement comprising: said flange portion including a first hole having vibration absorbing coupling means fixedly disposed therein for coupling the flange portion to the bolt-nut mechanisms and absorbing compressor vibration; said coupling means including a cylindrical bushing fixedly disposed in said first hole and attaching members for attaching said bushing to the bolt-nut mechanisms; said cylindrical bushing comprising an outer cylinder, an inner cylinder and a vibroisolating rubber member fixedly disposed between said outer and inner cylinders and bonded thereto; and each attaching member including a bar inserted into said inner cylinder and a cylindrical portion connected to said bar wherein said cylindrical portion includes a second hole for receiving the bolt-nut mechanisms.
Claim 2
Dependent Claim
