    Abstract: In a hermetic compressor for use on an air-conditioning unit as well as a refrigerating unit such as a refrigerator and a showcase, there is disclosed a constitution designed to provide a silently operated hermetic compressor that has an intake muffler readily assembled thereon. The hermetic compressor including a substantially disk-like elastic member disposed between the intake muffler at an outlet thereof and a cylinder head is provided, in which an outlet orifice of the intake muffler constantly remains pressed against an intake valve port through a gasket.

    Abstract: 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.

    Abstract: The present invention is contemplated to provide a hermetic motor-driven compressor which 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 means, 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.

    Abstract: A closed motor-driven compressor includes a compression component (2) and an electric component (3) for driving the compression component (2), both of which are elastically supported within a closed vessel (1). A suction muffler (8) is mounted on the compression component (2) and includes a plurality of elements (10, 11, 12; 14, 15, 16; 18, 19, 20; 22, 23, 24; 26, 27, 28) assembled together and each made of synthetic resin. One of the plurality of elements (10, 11, 12; 14, 15, 16; 18, 19, 20; 22, 23, 24; 26, 27, 28) has a guide rib (13; 17; 21) integrally formed therewith that is tapered down toward an adjoining one of the plurality of elements (10, 11, 12; 14, 15, 16; 18, 19, 20; 22, 23, 24; 26, 27, 28), thereby facilitating assembly of the two elements.
