A SUCTION ARRANGEMENT IN A RECIPROCATING HERMETIC COMPRESSOR

摘要

A hermetically sealed shell (21) contains a reciprocating hermetic compressor that has a suction inlet tube (28) for admitting gas into the shell; a suction orifice (24a) which is provided at the head of a cylinder (22) disposed inside the shell (21) and which is in fluid communication with the suction inlet tube (28). A suction duct (60) has a first end (61) hermetically coupled to the suction inlet tube (28) and a second end (62) hermetically coupled to the compressor suction orifice inlet (24a) and conducts low pressure gas from the suction inlet tube (28) directly to the suction orifice (24a) inside of shell (21), the suction duct (60) providing thermal and acoustic energy insulation to the gas being drawn into the compressor and is dimensioned to produce a load loss reduction in the gas flow from the suction inlet tube (28) to the suction orifice (24a).
