Abstract: A HERMETIC COMPRESSOR OF THE PRESENT INVENTION IS PROVIDED WITH ONE OR MORE SMALL HOLES 17 FORMED IN THE SHELL OF THE SUCTION MUFFLER 16 FORMED WITH A LOW THERMAL CONDUCTIVITY MATERIAL SUCH AS SYNTHETIC RESIN. THE SMALL HOLES 17 ARE POSITIONED AT NODES 18 IN A VIBRATION MODE FOR THE RESONANCE FREQUENCY OF THE SPACE FORMED IN THE HERMETIC SHELL, SO THAT AMPLIFICATION OF THE RESONANCE SOUND OF THE SPACE IN THE HERMETIC SHELL 1 IS SUPPRESSED. FURTHERMORE, A SHORTAGE OF THE REFRIGERANT IS SUPPLEMENTED BY THE REFRIGERANT GAS SUCKED FROM THE HERMETIC SHELL 1 THROUGH THE SMALL HOLES 17 WHEN IT OCCURS DUE TO A SUCTION LOSS CAUSED BY THE RESISTANCE OF THE FLOW PATH FOR GUIDING A HIGH DENSITY REFRIGERANT GAS FROM THE SUCTION TUBE INTO THE CYLINDER 8 ACCORDING TO THE CIRCULATION OF THE REFRIGERANT.
