Abstract:
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, said wraps interfitting to define compression chambers; a housing including an end cap enclosing said orbiting and said non-orbiting scroll, said housing defining a discharge pressure chamber on one side of said nonorbiting scroll and a suction pressure chamber being defined on an opposed side of said non-orbiting scroll; a back pressure chamber behind said base of said orbiting scroll; said non-orbiting scroll being urged towards said orbiting scroll by a spring providing a force between said end cap and said non-orbiting scroll; and a discharge port to communicate a compressed refrigerant from said compression chamber to said discharge chamber, said discharge chamber providing a pressure force holding said non-orbiting scroll by urging said non-orbiting scroll toward said orbiting scroll, and a suction port on said opposed side of said non-orbiting scroll and supplying a suction pressure refrigerant into said suction chamber.
