Abstract

A compressor may include a shell assembly, a compression mechanism and a conduit. The shell assembly may include a fitting through which fluid is received from outside of the compressor. The compression mechanism may be disposed within a chamber defined by the shell assembly. The conduit may extend through the chamber between the fitting and a suction inlet of the compression mechanism and transmit at least a portion of the fluid from the fitting to the suction inlet. The conduit may include an inlet that may be spaced apart from the fitting and an outlet that may engage the compression mechanism.

First claim

What is claimed is:

1. A compressor comprising:
a shell assembly having a fitting through which fluid is received from outside of the compressor, said shell assembly having a longitudinal axis;
a compression mechanism comprising a non-orbiting scroll disposed within a chamber defined by said shell assembly, said non-orbiting scroll haying a longitudinal axis that is parallel to said longitudinal axis of said shell assembly; and
a conduit extending through said chamber between said fitting and a suction inlet of said compression mechanism and transmitting at least a portion of said fluid from said fitting to said suction inlet, said conduit including an inlet that is spaced apart from said fitting and an outlet that engages said compression mechanism,
wherein said conduit includes a mounting flange having mounting apertures and a pair of tabs extending laterally outward from said mounting flange in opposite directions and sealing said conduit against a said non-orbiting scroll, said tabs are spaced apart from said mounting apertures in a direction parallel to said longitudinal axis of said shell assembly.

2. The compressor of claim 1 , wherein said conduit includes a bulged portion, said inlet is disposed between said bulged portion and a longitudinal axis of said shell assembly.

3. The compressor of claim 2 , wherein said conduit includes an integrally formed rib extending outward therefrom disposed proximate said outlet and between a pair of mounting apertures in said conduit, said rib extending vertically upward from said mounting flange such that an uppermost portion of said rib is disposed vertically higher than said mounting flange.

4. A compressor comprising:
a shell assembly having a fitting through which fluid is received from outside of the compressor, said shell assembly having a longitudinal axis;
a compression mechanism comprising a non-orbiting scroll disposed within a chamber defined by said shell assembly, said non-orbiting scroll having a longitudinal axis that is parallel to said longitudinal axis of said shell assembly; and
a conduit extending through said chamber between said fitting and a suction inlet of said compression mechanism and transmitting at least a portion of said fluid from said fitting to said suction inlet, said conduit including an inlet that is spaced apart from said fitting and an outlet that engages said compression mechanism, said conduit including a bulged portion, said inlet is disposed radially between said bulged portion and said longitudinal axis of said shell assembly,
wherein said conduit includes a mounting flange having mounting apertures and a pair of tabs extending laterally outward from said mounting flange in opposite directions and sealing said conduit against said non-orbiting scroll, wherein said tabs are spaced apart from said mounting apertures in a direction parallel to said longitudinal axis of said shell assembly.

5. The compressor of claim 4 , wherein said conduit includes an aperture spaced apart from said inlet and said outlet and providing fluid communication between said conduit and said chamber.

6. The compressor of claim 4 , wherein said conduit is spaced apart from said fitting and said shell assembly.

7. The compressor of claim 4 , wherein said conduit includes an integrally formed rib extending outward therefrom.

8. The compressor of claim 7 , wherein said rib is disposed proximate said outlet and between a pair of mounting apertures in said conduit.

9. The compressor of claim 8 , wherein said rib extends from the mounting flange in a direction perpendicular to said tabs.

10. The compressor of claim 9 , wherein said conduit includes a pair of threaded bushings receiving fasteners that fixedly secure said conduit to a non-orbiting scroll.

11. The compressor of claim 4 , wherein said conduit includes a mounting flange having a pair of threaded bushings receiving fasteners that fixedly secure said conduit to a non-orbiting scroll.

12. A compressor comprising:
a shell assembly having a fitting through which fluid is received from outside of the compressor, said shell assembly having a longitudinal axis;
a compression mechanism comprising a non-orbiting scroll disposed within a chamber defined by said shell assembly, said non-orbiting scroll haying a longitudinal axis that is parallel to said longitudinal axis of said shell assembly; and
a conduit extending through said chamber between said fitting and a suction inlet of said compression mechanism and transmitting at least a portion of said fluid from said fitting to said suction inlet, said conduit including an inlet that is spaced apart from said fitting and an outlet that engages said compression mechanism, said conduit including an aperture spaced apart from said inlet and said outlet and providing fluid communication between said conduit and said chamber, said conduit including a bulged portion, said inlet is disposed radially between said bulged portion and said longitudinal axis of said shell assembly, said conduit including a mounting flange having mounting apertures and a pair of sealing tabs extending laterally outward from said mounting flange in opposite directions and sealing said conduit against said non-orbiting scroll,
wherein said conduit includes an integrally formed rib extending outward therefrom, said rib is disposed proximate said outlet and between a pair of mounting tabs on said mounting flange, wherein said mounting apertures extend through said mounting tabs,
wherein said rib extends from the mounting flange in a direction perpendicular to said sealing tabs, said rib extends vertically upward from said mounting flange such that an uppermost portion of said rib is disposed vertically higher than said mounting flange such that said outlet of said conduit is disposed vertically between said inlet of said conduit and an uppermost edge of said rib,
wherein said sealing tabs are spaced apart from said mounting tabs and said mounting apertures, said sealing tabs are disposed in a different plane than said mounting tabs.

13. The compressor of claim 12 , wherein said conduit is spaced apart from said fitting and said shell assembly.

14. The compressor of claim 12 , wherein said mounting flange includes a pair of threaded bushings receiving fasteners that fixedly secure said conduit to a non-orbiting scroll.
