Abstract

A vibration isolation mount for a compressor that is formed of an elastomeric material and includes a sleeve, tapered studs or axial ribs spaced around the sleeve, and a lip seal extending around the sleeve. The mount is intended to be located between a compressor and a housing. The studs or ribs then deform to isolate the housing from radial vibration of the compressor, and the lip seal creates an annular seal between the housing and the compressor.

Claims

1. A vibration isolation mount for a compressor, wherein the mount is formed of an elastomeric material and comprises a sleeve, a plurality of tapered studs or axial ribs spaced around the sleeve, and a lip seal extending around the sleeve.

2. The vibration isolation mount of claim 1, wherein the lip seal is more compliant radially than the studs or ribs.

3. The vibration isolation mount of claim 1, wherein the seal is located at one end of the sleeve.

4. A product comprising a compressor, a housing, and a vibration isolation mount, wherein the mount is formed of an elastomeric material and comprises a sleeve, a plurality of tapered studs or axial ribs spaced around the sleeve, and a lip seal extending around the sleeve, the mount is located between the compressor and the housing, the studs or ribs deform to isolate the housing from radial vibration of the compressor, and the lip seal creates an annular seal between the housing and the compressor.

5. The product of claim 4, wherein the lip seal is more compliant radially than the studs or ribs.

6. The product of claim 4, wherein the seal of the vibration isolation mount is located at one end of the sleeve.

7. The product of claim 4, wherein the compressor comprises an axial inlet through which fluid enters the compressor and a radial outlet through which fluid exits the compressor, the inlet is located at one end of the compressor, and the annular seal is created at a position between the outlet and the opposite end of the compressor.
