Abstract: A compressor used in a refrigerating cycle is provided as a miniaturized and lightweight unit at low production cost by selecting an optimal material to constitute components or by forming the housing in a specific shape so as to allow the components to have smaller wall thicknesses while assuring sufficient strength. A tough material achieving a tensile strength greater than 800 N/mm2 is used when forming at least one of the components constituting the housing and the internal mechanisms. In addition, over the area of the housing where the bottom surface and the inner circumferential surface connect with each other, the bottom surface forms an R-shaped portion and the inner circumferential surface forms a sloping portion or an R-shaped portion.

Abstract: A compressor for receiving at least one compression element in a sealed container is provided. The sealed container comprises a container body and a cover member for blocking an opening of the container body, both of which are made of an aluminum material. The cover member is electrically welded to the container body over an entire circumference of the cover member, and thick ribs with a thickness dimension extending from a circumference portion to a central portion are formed with a predetermined pitch on the cover member. In this manner, an increase in the manufacturing cost and a reduction of the workability can be substantially suppressed, while the reliability of the sealed container of the compressor and the aluminum members assembled by arc welding can be substantially improved.
