1. A scroll machine comprising:
- an outer shell;
a first scroll compressor disposed within said outer shell;
a second scroll compressor disposed within said outer shell;
a drive shaft extending between said first and second scroll compressors, said drive shaft having a first drive flat at a first end engaging said first scroll compressor and a second drive flat at a second end engaging said second scroll compressor, said first and second drive flats being out of rotational phase with one another by 180°
; and
a motor disposed within said outer shell between said first and second scroll compressors, said motor being drivingly coupled to said drive shaft for rotatably driving said drive shaft.

Abstract
A compressor system includes a pair of compressors located in a common shell. A common drive shaft drives both compressors and the drive shaft is powered by a single motor. One or both of the compressors can be equipped with a pulse width modulated capacity control system and a vapor injection system. When one compressor is equipped with these systems, the capacity can be varied between 50% and 110%. When both compressors are equipped with these systems, the capacity can be varied between 0% and 120%.
