Abstract: The present invention provides an hermetic electric compressor capable of stably supplying oil to a compression chamber with a low noise level. The hermetic electric compressor has a closed vessel, an electric element, a compressing element that is disposed over the electric element and driven by the electric element, and an oil reservoir. The hermetic electric compressor also has an oil supply mechanism for supplying the oil from the oil reservoir to the compressing element in the closed vessel, and a suction muffler that communicates with a refrigerant suction part for sucking a refrigerant into the compressing element and is formed of a box body having a predetermined spatial volume. The suction muffler is positioned below the position where the oil is supplied into the closed vessel, and the box body has at least one oil suction port used for sucking a predetermined amount of oil.

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.

Abstract: A pair of connection passages allowing a movable valve and a closed container to communicate with the muffling space, is openably extended into the muffling space of a suction muffler. A resonance muffler with an opening in either of two chambers, is formed. The columnar resonance frequency in the other chamber, is same as that in closed container.

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.
