Claims
- 1. A mounting grommet for compressors adapted for attachment to the mounting feet thereof and to the compressor mounts of a refrigeration unit, comprising an elastomeric, generally cylindrical body having an inner end and outer end and having a substantially axially positioned bore therethrough, said grommet being adapted for attachment to a compressor mount by bolt means passing through the bore of said body and abutting said outer end and affixed to said mount adjacent said inner end, a radially peripheral portion of said body being formed intermediate said ends thereof to provide upwardly extending annular shoulder means adapted to contact and support a compressor foot and receive substantial downward force therefrom, the radially inner surface of said shoulder means being spaced from radially outer and adjacent portions of said body which contain said bore, and the radially outer surface of said shoulder means lying radially outwardly of all other peripheral portions of said body.
- 2. The grommet of claim 1 wherein the base of said shoulder means provides a diagonal distortion line in response to the application of downward force to said shoulder means.
- 3. The grommet of claim 2 wherein said distortion line is downwardly and radially outwardly directed.
- 4. The grommet of claim 3 wherein the base of said shoulder means is integral with an underlying annular portion of said body, which portion lies radially inwardly of the radially outer surface of said shoulder means.
- 5. The grommet of claim 4 affixed to a compressor mount and having its shoulder means contacting and supporting a compressor foot, whereby downward force on said shoulder means places it in said diagonal distortion.
- 6. The grommet of claim 5 wherein said diagonal distortion dislocates the mean vertical axis of said shoulder means radially outwardly.
- 7. A refrigeration compressor having its mounting feet supported by grommets affixed to the compressor mounts within the shell of a compressor unit, each of said grommets comprising an elastomeric, generally cylindrical body attached to a compressor mount by bolt means passing through the bore of said body, a radially peripheral portion of said body being formed intermediate the length of said body to provide upwardly extending annular shoulder means contacting and supporting a compressor foot and receiving substantial downward force therefrom, the radially inner surface of said shoulder means being spaced from radially outer and adjacent portions of said body, and the radially outer surface of said shoulder means lying radially outwardly of all other peripheral portions of said body.
- 8. The compressor of claim 7 wherein the base of said shoulder means provides a diagonal distortion line in response to the application of downward force to said shoulder means.
- 9. The compressor of claim 8 wherein said distortion line is downwardly and radially outwardly directed.
- 10. The compressor of claim 9 wherein the base of said shoulder means is integral with an underlying annular portion of said body, which portion lies radially inwardly of the radially outer surface of said shoulder means.
- 11. The compressor of claim 10 wherein said downward force on said shoulder means places it in said diagonal distortion.
- 12. The grommet of claim 1 wherein the elastomer has a Durometer hardness of from about 25 to about 100.
- 13. The grommet of claim 12 wherein the elastomer is ethylene-propylene terpolymer (EPDM).
- 14. The grommet of claim 10 wherein from about 1/3 to about 2/3 of the mass of said shoulder means lies radially outwardly of said underlying annular portion.
