Abstract: A scroll compressor includes a compressor housing, an orbiting scroll member, a non-orbiting scroll member, an economizer injection inlet, and a discharge outlet. The orbiting scroll member and the non-orbiting scroll member are disposed within the compressor housing. The orbiting scroll member and the non-orbiting scroll member are intermeshed thereby forming a compression chamber within the compressor housing. The non-orbiting scroll includes at least one compression inlet port. An economizer injection inlet is formed through the compressor housing and in fluid communication with the compression chamber via the at least one compression inlet port. The discharge outlet is in fluid communication with the compression chamber.

The orbiting scroll member and the non-orbiting scroll member are disposed within the compressor housing. The orbiting scroll member and the non-orbiting scroll member are intermeshed thereby forming a compression chamber within the compressor housing. The non-orbiting scroll includes a plurality of compression inlet ports. An economizer injection inlet is formed through the compressor housing and in fluid communication with the compression chamber via the compression inlet ports. The economizer injection inlet is disposed between the non-orbiting scroll member and the compressor housing. The discharge outlet is in fluid communication with the compression chamber.

Abstract: A scroll compressor includes an orbiting scroll member disposed within a compressor housing. The orbiting scroll member has a substantially circular baseplate and a generally spiral wrap extending from its base. A first seal is disposed proximal to the outer periphery of the orbiting scroll baseplate to provide an external seal between the baseplate and the housing. A second seal is disposed radially inward from the first seal to provide an internal seal between the baseplate and the housing. A space between the internal seal and the external seal defines a balance piston chamber. The balance piston chamber is pressurized via a high or intermediate pressure oil source to reduce thrust loading on the baseplate caused by an axial pressure differential across the baseplate.
