Abstract: A hermetic compressor with an improved operating efficiency for use in a cold storage, freezing chamber or the like, in which a suction pipe (23) is located with its one end (23e) in the vicinity of an inlet opening (22) of a suction muffler (17) so that heat of a closed casing (1) is not easily transmitted to the suction pipe (23) for less heating of the cooling medium gas drawn in, and thus, cooling efficiency is improved by preventing discharge of the low density cooling medium into the cooling system through compression of the expanded cooling medium gas.

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: A sealed-type motor compressor comprises motor and compressor sections resiliently supported within a sealed enclosure, with a suction pipe extending through a side wall of the enclosure, a suction muffler on a side wall of the section, and an insert pipe extending into the interior of the enclosure with a slight clearance between the insert pipe and an inlet port formed in a side wall of the muffler. A closely coiled cylindrical spring interconnects the suction insert pipes and has a torsional moment biasing the insert pipe against the inlet port. The suction muffler includes a cup-shaped synthetic resin body divided into upper and lower sections, a closure member covering an opening of the body and a partition plate mounted between the body and the closure member, the cup-shaped body being open at its top surface and formed at its bottom surface with an aperture through which a communication pipe is fitted into a suction port in the compressor section. The partition plate is formed with a through hole having a position which is offset from an extension of the communication pipe, and the inlet port is provided on a side of the closure member.
