Compressor Patents (Class D15/9)
  • Patent number: 4345882
    Abstract: A hermetic motor compressor comprises a casing which includes a dome-like upper casing and a dome-like lower casing. Each of the upper and lower casings has an engagement portion for telescopically engaging with each other. The stiffness of the upper casing is increased by making at least three corner portions close to the engagement portion. Crescent-shaped portions, curved surfaces, an apex portion and crest lines are also provided for the upper casing. This specific structure of the upper casing may be made also for the lower casing, and when both of the upper and lower casings have such construction, the corner portions of the upper casing and the corner portions of the lower casing are arranged alternatively so that the vibrating modes of respective casings offset each other. The shape of the entire casing may be spherical or ellipsoidal.
