    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: A hermetic compressor comprising a compressing mechanism and a housing for encasing the compressing mechanism, the housing comprising upper and lower portions which are coupled to each other and being formed to have curved surfaces. The housing is constructed such that one curved line on the housing is arranged to be different from other curved lines existing at positions symmetrical with a position of the one curved line with respect to planes X, Y and Z perpendicular to one another and passing the housing, the plane X including a boundary portion between the upper and lower portions of the housing and being perpendicular to a center line passing through a center of an upper surface of the upper portion and a center of a bottom surface of the lower portion, and the planes Y and Z being perpendicular to each other and perpendicular to the plane X and including the center line.

    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 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.
