摘要

A low volume inlet reciprocating compressor suitable for use in a dual evaporator refrigeration cycle. The compressor includes a cylinder having an inlet port and an outlet port disposed in a housing. A flexible conduit having an inlet passage formed therein extends between the inlet port and an inlet in the housing, and a check valve is connected to the inlet passage so as to prevent refrigerant flow out of the conduit. The inlet passage is located as close as possible to the inlet port. A suction muffler can be located in the housing with one end connected to a second inlet in the housing and another end connected to the check valve. A discharge tube is provided between the outlet port and outlet opening in the housing.
