摘要： A compressing unit of a hermetic compressor includes a suction valve placed at an opening of a compressing room and a suction muffler. The muffler includes a suction muffler body which forms a sound-deadening space, a first communicating path which communicates with the suction valve and with the sound-deadening space, and a second communicating path which communicates with a hermetic container and with the sound-deadening space. An opening, situated in the sound-deadening space, of the first communicating path, and an opening, situated in the sound-deadening space, of the second communicating path are both open in the same direction. In addition, a sound-insulating wall is disposed on the wall of the muffler body at a place at least confronting both of the openings. This structure achieves low noise and high efficiency.

摘要： This relates to a hermetic compressor and a manufacturing method of a suction muffler, and discloses a technique for making energy efficiency higher and reducing noise. According to that technique, in a suction muffler 140 having a sound attenuation space 143, by foam-molding a wall 147, such as an opposite surface and the like, where open ends 145a, 146a within the sound attenuation space among the walls constituting a casing 140C of the suction muffler 140 are opened, it is possible to reduce the heating action of refrigerant gas released into the sound attenuation space 143 effectively in a space-saving manner, and make a sucking efficiency higher, and effectively absorb a refrigerant pulsation tone radiated in the open end 145a within the sound attenuation space, and consequently reduce the noise.

摘要： A hermetic compressor includes a closed vessel for storing lubricating oil, an electric-driving element, and a compressing element driven by the electric-driving element. The compressing element includes a cylinder block forming a compression chamber, a piton that reciprocates inside the compression chamber, and an oiling device for supplying the lubricating oil to an outer circumference of the piston. A first oil groove is concavely formed on the outer circumference of the piston, and a second oil groove is concavely formed on a side opposite to the compression chamber relative to the first oil groove. The second oil groove has a spatial volume same or greater than that of the first oil groove. An expanded clearance portion is provided such that a clearance between the piston and the cylindrical hole portion broadens from a top dead point to a bottom dead point.
