DICHT ABGESCHLOSSENER SPIRALKOMPRESSOR

摘要

A hermetic scroll compressor has a scroll compressor section, a motor section and a hermetic casing which encases the compressor and motor sections. The space in the casing is divided into an upper chamber and a lower chamber by a frame by which a shaft interconnecting the compressor and motor sections is rotatably supported. The upper and lower chambers are communicated with each other through a communication passage which is formed in the outer periphery of the frame. The hermetic casing is composed of an upper section, a barrel section and a lower section which are welded together. The barrel section is formed by rolling a sheet into a cylindrical form and welding opposing ends of the rolled sheet so as to form a weld seam joint. The frame is fixed in the casing with the weld seam joint disposed within the circumferential width of the communication passage, so that the outer periphery of the frame is in tight contact with the inner periphery of the barrel section except for the portion where the communication passage is formed.
