A refrigeration system has a compressor which incorporates fluid injection into one or more of the fluid pockets. A source of fluid for injection into the pockets is attached directly to the shell of the compressor to eliminate the need for having fluid piping between the source of fluid and the compressor. The source of fluid can be a flash tank which increases the capacity and efficiency of the system or the source of fluid can be a heat exchanger which also increases the capability and efficiency of the system.

An assembly as set forth in claim 1 wherein said spacer is further defined as a spacer clip engaging said upper edge of said outer shell and compressed between said inner housing and said outer shell. 13. An assembly as set forth in claim 12 wherein said first plurality of recessed portions and said second plurality of recessed portions are radially offset from one another whereby said first plurality of recessed portions and said second plurality of recessed portions alternate around said inner housing and said outer shell. 14. An assembly as set forth in claim 12 wherein said spacer clip further includes a U-shaped portion for engaging said edge and a raised dimple being compressed between said inner housing and said outer shell. 15. An assembly as set forth in claim 12 wherein said spacer clip further includes a U-shaped portion for engaging said edge and a tab being compressed between said inner housing and said outer shell. 16. An assembly as set forth in claim 1 wherein said spacer is further defined as a bump integrally formed in said side walls and engaging said inner housing. 17. An assembly as set forth in claim 1 further including a cap engaging said outer shell and enclosing said inner housing within said outer shell and said cap. 18. An assembly as set forth in claim 17 further including cap clips extending from said cap for engaging said outer shell and securing said cap to said outer shell. 19. An assembly as set forth in claim 1 wherein said spacers define a predetermined distance between said inner housing and said outer shell to establish said chamber. 20. An assembly as set forth in claim 19 wherein said predetermined distance is selected from a range of about 0.05 inches to about 0.50 inches. 21. An assembly as set forth in claim 19 wherein said predetermined distance is selected from a range of about 0.10 inches to about 0.35 inches. 22.
