摘要： 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.
