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 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.
