SCROLL COMPRESSOR HAVING CAPACITY MODULATION SYSTEM

摘要

A compressor may include a housing, orbiting and non-orbiting scroll members, a first porting, and a second porting. The first and second porting may each extend through the end plate of the non-orbiting scroll member and may each have an angular extent of at least twenty degrees. An ending point of the first porting may be rotationally spaced from a starting point of the first porting by the angular extent in a rotational direction of a drive shaft of the compressor. An ending point of the second porting may be rotationally spaced from a starting point of the second porting by the angular extent in a rotational direction opposite the rotational direction of the drive shaft. The ending point of the second porting may be rotationally spaced from the starting point of the first porting by less than one hundred and eighty degrees in the rotational direction of the drive shaft
