Capacity modulated scroll compressor

A system including a compressor, the compressor comprising:

• an orbiting scroll member having a first end plate and a first spiral wrap;
• a non-orbiting scroll member having a second end plate and a second spiral wrap, wherein the second spiral wrap forms a meshing engagement with the first spiral wrap to create a plurality of compression chambers between a suction port and a discharge port of the orbiting scroll member and the non-orbiting scroll member;
• a first port in communication with a first of the plurality of compression chambers and selectively injecting an injection fluid into the first of the plurality of compression chambers to increase a compressor capacity and selectively leaking a first compressed fluid from the first of the plurality of compression chambers to reduce the compressor capacity;
• a second port in communication with a second of the plurality of compression chambers and selectively leaking a second compressed fluid from the second of the plurality of compression chambers to reduce a compressor capacity;
• a first passage in communication with the first port and a first fitting to transport fluid between the first of the plurality of compression chambers and the first fitting;
• and
• a second passage in communication with the second port and a second fitting to transport the second compressed fluid from the second of the at least one compression chamber.
