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: 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.

Abstract: An enclosed motor-driven compressor includes a vertical crankshaft (25) rotatably supported by two ball bearings (26, 27) and having an eccentric portion (28) through which a motor element (21) and a compressor element (22) are operatively connected. The two ball bearings (26, 27) are disposed on opposite sides of the eccentric portion (28) so that a reaction force of a piston (35) which is exerted on the eccentric portion (28) is supported evenly by the ball bearings (26, 27). With the ball bearings (26, 27) thus arranged, the load on the crankshaft (25) is lowered and the efficiency of the motor element (21) is increased. A lubricating oil (33) held at the bottom of a container (20) is sucked through an internal groove of the crankshaft (25) and then supplied from outlets (37b, 37c) to the respective ball bearings (26, 27). The ball bearings (26, 27) thus lubricated have a prolonged service life. The compressor may have an oil sump disposed either above or below the ball bearing (26) for improving lubricating condition of the ball bearing (26).

Abstract: 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.
