Abstract
A scroll compressor has a non-orbiting scroll axially secured within an end cap without being mechanically fixed to the end cap. The compressor is of the sort wherein the back pressure chamber is defined behind the orbiting scroll. In one embodiment a spring biases the non-orbiting scroll toward the orbiting scroll. In other embodiments the non-orbiting scroll is force fit within the end cap.

A scroll compressor comprising:
- a non-orbiting scroll having a base and a generally spiral wrap extending from said base;
- an orbiting scroll having a base and a generally spiral wrap extending from said base;
- a housing including an end cap enclosing said orbiting and said non-orbiting scroll;
- a back pressure chamber designed behind said base of said orbiting scroll;
- and
- said non-orbiting scroll being held against movement within said end cap without being mechanically fixed to said end cap.
