Abstract
Abstract The present invention provides a hermetic refrigeration compressor installation comprising an outer housing containing a refrigeration compressor, a plurality of indentations in the outer housing, a plurality of resilient grommets each having a grommet tip received within a respective one of the indentations, and a bonding between the grommets and the indentations for securing the grommets therein. Further provided is a base separate from the refrigeration compressor and outer housing, and projections on the base for mounting the grommets securely thereon. The method of the present invention comprises forming a plurality of indentations in the outer housing, providing a plurality of resilient grommets each having a grommet tip, adhesively securing each one of the grommet tips in a respective one of the indentations, and connecting the grommets securely to thebase.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
117 words
A hermetic refrigeration compressor installation comprising: an outer housing containing a refrigeration compressor unit and hermetically sealing the unit from the ambient environment, a plurality of indentations in an outer surface of said outer housing, a plurality of generally elastic grommets each having a bore therein, each of said grommets having a grommet tip adhesively secured within its corresponding indentation, and a base separate from said housing and having a plurality of projections, each of said projections being positioned on the base so as to be in general axial alignment with the bore of its corresponding grommet, said projection being received and secured within the bore so that the outer housing is resiliently mounted to the base.
Claim 2
Dependent Claim
117 words
A hermetic refrigeration compressor installation comprising: an outer housing containing a refrigeration compressor unit and hermetically sealing the unit from the ambient environment, a plurality of indentations in an outer surface of said outer housing, a plurality of generally elastic grommets each having a bore therein, each of said grommets having a grommet tip adhesively secured within its corresponding indentation, and a base separate from said housing and having a plurality of projections, each of said projections being positioned on the base so as to be in general axial alignment with the bore of its corresponding grommet, said projection being received and secured within the bore so that the outer housing is resiliently mounted to the base.
Claim 3
Dependent Claim
37 words
The hermetic refrigeration compressor installation of claim 1 wherein the end portions of said grommets which are adjacent to said base extend beyond said outer housing so that the outer surface is spaced apart from the base.
Claim 4
Dependent Claim
27 words
The hermetic refrigeration compressor installation of claim 1 wherein said projections are tangs each having a plurality of barbs thereon, said barbs being embedded in said grommets.
Claim 5
Dependent Claim
17 words
The hermetic refrigeration compressor installation of claim 3 wherein said tags are stamped out of said base.
Claim 6
Dependent Claim
28 words
The hermetic refrigeration compressor installation of claim 1 wherein said projections are pins mounted securely within said grommets by an adhesive layer between said pins and said grommets.
Claim 7
Dependent Claim
56 words
The hermetic refrigeration compressor installation of claim 1 wherein said projections are tabs each having an opening generally horizontally disposed therethrough, said grommets each have an aperture therethrough, said aperture being generally normally disposed to said bore, and said tabs are mounted securely to said grommets by locking pins received through said openings and said apertures.
Claim 8
Dependent Claim
17 words
The hermetic refrigeration compressor installation of claim 6 wherein said tabs are stamped out of said base.
Claim 9
Dependent Claim
28 words
The hermetic refrigeration compressor installation of claim 1 wherein the base includes a generally planar surface disposed in a generally parallel fashion with respect to said outer surface.
Claim 10
Dependent Claim
20 words
The hermetic refrigeration compressor installation of claim 1 wherein said indentations form a continuous surface recessed away from said base.
Claim 11
Independent Claim
75 words
A method of resiliently mounting to a base a hermetic refrigeration compressor having a hermetically sealed oiuter housing, said method comprising: forming a plurality of indentations in an outer surface of the housing, providing a plurality of elastic grommets each having a grommet tip, applying an adhesive to the surfaces of the indentations, positioning each one of the grommet tips in its corresponding one of the indentations, and connecting the grommets securely to the base.
Claim 12
Independent Claim
75 words
A method of resiliently mounting to a base a hermetic refrigeration compressor having a hermetically sealed oiuter housing, said method comprising: forming a plurality of indentations in an outer surface of the housing, providing a plurality of elastic grommets each having a grommet tip, applying an adhesive to the surfaces of the indentations, positioning each one of the grommet tips in its corresponding one of the indentations, and connecting the grommets securely to the base.
Claim 13
Dependent Claim
17 words
The method of claim 10 wherein each of the grommets further includes a bore generally axially therein.
Claim 14
Dependent Claim
37 words
The method of claim 10 including stamping out of the base a plurality of projections upstanding from the base and embedding the projections in the grommets by axial movement of the base relative to the outer surface.
Claim 15
Dependent Claim
62 words
The method of claim 12 wherein the step of connecting the grommets securely to the base further includes placing the outer housing apart from the base such that each one of the grommet bores is axially aligned directly above a respective one of the projections, and axially drawing the outer housing against the base whereby the projections are received within the bores.
Claim 16
Dependent Claim
120 words
A housing for hermetically sealing a refrigeration compressor and being mountable to a generally planar surface of a separate base wherein the planar surface has a plurality of projections, the housing comprising: a generally planar outer surface disposed so as to be generally parallel with respect to the base planar surface and having a plurality of continuous identations formed therein, each of said indentions being recessed away from the base planar surface; and a plurality of elastic grommets, each of said grommets being adhesively secured within its corresponding said indention, each of said elastic grommets having a central bore in which a corresponding one of said projections is received so as to resiliently mount the housing to the separate base.
Claim 17
Dependent Claim
120 words
A housing for hermetically sealing a refrigeration compressor and being mountable to a generally planar surface of a separate base wherein the planar surface has a plurality of projections, the housing comprising: a generally planar outer surface disposed so as to be generally parallel with respect to the base planar surface and having a plurality of continuous identations formed therein, each of said indentions being recessed away from the base planar surface; and a plurality of elastic grommets, each of said grommets being adhesively secured within its corresponding said indention, each of said elastic grommets having a central bore in which a corresponding one of said projections is received so as to resiliently mount the housing to the separate base.
