Abstract
A scroll compressor assembly incorporates a separator plate which has a clearance between its outer periphery and an inner periphery of an end cap. In this way, the location of the separator plate along the center axis of the scroll can be adjusted. Further, the separator plate is placed on the center shell prior to attachment of the end cap. Thus, the separator plate need not be welded to the end cap as in the prior art. Problems such as weld splatter thus eliminated.
Claims16
A compressor comprising:
- a center shell defining an interior volume;
- a motor received in said interior volume, said motor driving a shaft;
- a compressor pump unit driven by said shaft, said compressor pump unit being received within said interior volume;
- a suction supply for supplying a suction pressure refrigerant into said interior volume;
- a discharge port extending from said compressor pump unit, said communicating compressed gas from said compressor pump unit into a discharge pressure chamber;
- an end cap welded to said center shell;
- and
- a separator plate positioned at an end of said center shell, and defining a separation between said discharge pressure chamber and said interior volume, there being a clearance between an outer peripheral surface of said separator plate and an inner peripheral surface of said end cap so that said outer peripheral surface of said separator plate can be adjusted toward said inner peripheral surface of said end cap within said clearance.

A compressor comprising:
- a center shell defining an interior volume;
- a motor received in said interior volume, said motor driving a shaft;
- a compressor pump unit driven by said shaft, said compressor pump unit being received within said interior volume;
- a suction supply for supplying a suction pressure refigerant into said interior volume;
- a discharge port extending from said compressor pump unit, said communicating compressed gas from said compressor pump unit into a discharge pressure chamber;
- an end cap welded to said center shell;
- a separator plate positioned at an end of said center shell, and defining a separation between said discharge pressure chamber and said interior volume, there being a clearance between an outer peripheral surface of said separator plate and an inner peripheral surface of said end cap;
- and
- discharge pressure gas in said discharge pressure chamber biases said separator plate downwardly against said center shell.

A scroll compressor comprising:
- a first scroll member comprising a base and a generally spiral wrap extending from said base;
- a second scroll member including a base and a generally spiral wrap extending from said base;
- a shaft driven by an electric motor, said shaft driving said second scroll member to orbit relative to said first scroll member;
- a center shell surrounding said motor and said compressor pump unit;
- a suction tube for delivering a refrigerant to be compressed into said center shell, said motor and said compressor pump unit being received in an interior chamber within said shell which is at suction pressure;
- an end cap welded to said center shell;
- a discharge port extending through said first scroll member, and into a discharge pressure chamber;
- and
- a separator plate mounted above said first scroll member to separate said discharge pressure chamber from said interior chamber, said separator plate being held against an upper end of said center shell, but having a clearance between an outer peripheral surface and an inner peripheral surface of said end cap.
