摘要： In a hermetic compressor in a freezing refrigerating system or an air-conditioning system such as a refrigerator or a showcase, a construction is disclosed for intending to provide a low-noise hermetic compressor by effectively attenuating a pressure pulsation having occurred in a compression chamber with a suction muffler. By this construction, since a muffler cover 20 has a planar simple shape, the deformation upon molding becomes little and it can come into fully close contact with a muffler main body 19. Therefore, the pressure pulsation hardly leaks through the connecting portion between the muffler main body 19 and the muffler cover 20. The full silencing effect that the suction muffler 18 has is obtained and thereby noise can be reduced more effectively.

摘要： This invention relates to a hermetic compressor used on a refrigerant cycle such as a refrigerator, and discloses a low noise compressor designed to attenuate a resonance sound in a compression chamber and intake pressure pulsing more operatively at a position adjacent to their sources, which intake pressure pulsing occurs at an intake valve port. In the compressor, a resonance space 38 is provided adjacent to the intake valve port 29 that is closer in distance to a noise source. As a result, noise can be reduced more operatively than muffling functions of an intake muffler 31 do. In addition, although acoustic characteristics of the intake muffler 31 amplify noises having specific frequencies, such noises can be attenuated before being amplified.

摘要： A sealed electric compressor for use in, for example, an electric refrigerator, generates a little noise and can feed any moving part of its compressing element with refrigerator lubricant. An oil pickup tube is joined by insertion to the lowermost end of a crank shaft and includes a first centrifugal pumping portion and a second centrifugal pumping portion provided continuously and arranged at a smaller angle than that of the first centrifugal pumping portion. The second centrifugal pumping portion arranged at a smaller angle can spin in a pool of the refrigerator lubricant.

摘要： A hermetic motor-driven compressor is capable of decreasing both the resonance sound due to an oil feed pipe and the resonance sound due to a crankshaft generated when the oil feed pipe is rotated while being dipped in the refrigerating machine oil. Within a hermetically sealed enclosure, a compression component and a motor drive component are supported through an elastic support arrangement, and the compression component comprises a crankshaft adapted to be rotatively driven by the motor drive component through an eccentric portion and provided with a journal, a balance weight disposed at the eccentric portion and a coaxial oil feed pipe disposed in the balance weight so as to revolve coaxially with the journal, so that the stirring of the refrigerating machine oil can be suppressed.
