Abstract: An electrically-operated sealed compressor includes a cylinder, a cylinder head mounted on the cylinder and having a suction chamber and first and second discharge chambers, a piston accommodated in the cylinder, and a valve mechanism. The valve mechanism includes a suction muffler and a valve plate having at least one suction port, first and second discharge ports, and first and second pass holes. The first discharge port and the first pass hole communicate with the first discharge chamber, while the second discharge port and the second pass hole communicate with the second discharge chamber. The valve mechanism also includes first and second discharge valves mounted on the valve plate and accommodated in the first and second discharge chambers, respectively, a suction reed having a reed valve for selectively opening and closing the suction port, a discharge gasket for sealing the valve plate and the cylinder head, and a discharge muffler. The first and second discharge chambers are separated from each other by the discharge gasket to form respective independent spaces, while the first and second pass holes communicate with the discharge muffler.
Abstract translation: 电动密封式压缩机包括气缸，安装在气缸上并具有吸气室和第一和第二排气室的气缸盖，容纳在气缸中的活塞以及阀机构。 阀机构包括吸入消声器和具有至少一个吸入口，第一和第二排出口以及第一和第二通孔的阀板。 第一排出口和第一通过孔与第一排出室连通，而第二排出口和第二通过孔与第二排出室连通。 阀机构还包括安装在阀板上并分别容纳在第一和第二排出室中的第一和第二排出阀，该第一和第二排出阀分别具有用于选择性地打开和关闭吸入口的具有簧片阀的吸入簧片，用于密封阀 板和汽缸盖，以及排气消声器。 第一和第二排放室通过排放垫圈彼此分离以形成相应的独立空间，而第一和第二通孔与排放消音器连通。

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: 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 electric compressor including sealed container and coil spring provided for elastically supporting electric compression element housed in sealed container. A consideration has been made to avoid the coincidence in the resonance frequency between coil spring mounted with electric compression element and mechanical vibration caused by electric compression element, or a cavity formed in space. By so doing, creation of a resonation with coil spring is suppressed, and noises and vibrations with the hermetic electric compressors are reduced.
