Abstract:
A suction arrangement for a reciprocating hermetic compressor comprising:a hermetic shell;a suction inlet tube for admitting gas into the shell;a suction orifice at the head of a cylinder disposed inside the shell and which is in fluid communication with the suction inlet tube;a suction means having a first end hermetically coupled to the suction inlet tube and a second end hermetically coupled to the suction orifice for conducting low pressure gas from the suction inlet tube directly to the suction orifice, providing thermal and acoustic insulation to the gas flow being drawn; andat least one pressure equalizing means for providing a predetermined fluid communication of the gas being drawn between the suction inlet tube and suction orifice into the shell, the thermal and acoustic insulating characteristics of the suction means maintained substantially unaltered by the pressure equalizing means.
