Abstract
Scroll compressors having a non-orbiting scroll the type that moves axially for a limited distance are provided with an economizer fluid tube. The economizer tube is received within an opening in the non-orbiting scroll such that the non-orbiting scroll can move relative to the tube. This is an improvement over the prior art, and provides a more secure and simple connection.
Claims16
A scroll compressor comprising:
- a non-orbiting scroll member having a base and a generally spiral wrap extending from said base;
- an orbiting scroll member having a base and a generally spiral wrap extending from said base;
- said non-orbiting scroll member being axially moveable;
- said orbiting scroll member being operable to orbit relative to said first scroll member;
- a compressor shell that houses said first and second scroll members;
- an economizer tube for injecting refrigerant into the scroll compressor;
- and
- said economizer tube being relatively rigid and connected to a passage through said non-orbiting scroll member, said connection of said tube to said non-orbiting scroll member allowing said non-orbiting scroll member to move relative to said tube.

A scroll compressor comprising:
- a non-orbiting scroll member having a base and a generally spiral wrap extending from said base;
- an orbiting scroll member having a base and as generally spiral wrap extending from said base;
- said non-orbiting scroll member being axially moveable;
- said orbiting scroll member being operable to orbit relative to said first scroll member;
- a compressor shell that houses said first and second scroll members;
- an economizer tube for injecting refrigerant fluid into the scroll compressor;
- and
- a floating seal structure positioned on the base of said non-orbiting scroll member wherein said economizer tube injects refrigerant through said floating seal structure to a port in said base of said non-orbiting scroll member so that refrigerant fluid may be injected through said base of said first non-orbiting scroll member while at the same time permitting axial movement of said first non-orbiting scroll member.
