Abstract
A scroll compressor includes a housing, a non-orbiting scroll member including a first spiral wrap, and an orbiting scroll member including a second spiral wrap. The first and second spiral wraps are interleaved to define at least one moving fluid pocket that decreases in size as it moves from a radially outer position to a radially inner position. A vapor-injection system may include a shell fitting in fluid communication with a fluid passageway of the non-orbiting scroll member via a vapor injection tube. The vapor injection tube may be fixed for movement with the non-orbiting scroll member for communicating vapor into the moving fluid pockets.
Claims24
A scroll compressor comprising:
- a housing;
- a non-orbiting scroll member including a first end plate and a first spiral wrap upstanding therefrom, said non-orbiting scroll member being axially movable relative to said housing;
- an orbiting scroll member including a second end plate and a second spiral wrap upstanding therefrom, said first and second spiral wraps being interleaved to define a moving fluid pocket that decreases in size as it moves from a radially outer position to a radially inner position;
- a main bearing housing supporting said orbiting scroll member and including a fluid passageway;
- a tube fixed for movement with said non-orbiting scroll member and in fluid communication with said fluid passageway;
- and
- a port formed in said non-orbiting scroll member and in fluid communication with said tube to inject vapor into said at least one moving fluid pocket.
