A SUCTION ARRANGEMENT FOR A RECIPROCATING HERMETIC COMPRESSOR

摘要

A suction arrangement for a reciprocating hermetic compressor, including a hermetic shell (21), comprising a suction inlet tube (28) for gas admission; 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), said arrangement comprising a suction means (60) having a first end (61) and a second end (62), which are hermetically coupled to the suction inlet tube (28) and suction orifice (24a), respectively, in order to conduct low pressure gas from the suction inlet tube (28) directly to the suction orifice (24a), providing thermal and acoustic insulation to the gas flow being drawn; and at least one pressure equalizing means (70), providing a predetermined fluid communication of the gas being drawn between the suction inlet tube (28) and the suction orifice (24a) into the shell (21), maintaining substantially unaltered the thermal and acoustic insulating characteristics of the suction means (60).
