Claims
- 1. A hermetic type compressor comprising:
- a casing of a totally enclosed type;
- an electric motor accommodated in said casing for rotating a drive shaft;
- a compressor unit fitted in said casing and operatively connected to said electric motor for compressing a refrigerant,
- said compressor unit comprising a cylinder inserted into said casing so as to substantially contact with an inner surface of said casing, a roller coupled with an eccentric portion of the driving shaft so that said roller is eccentrically rotated in said cylinder, and a blade slidably contacting the outer surface of said roller to be reciprocable in a groove formed in said cylinder to divide the internal space of said cylinder into a suction chamber and a compression chamber,
- said casing being provided with reduced thickness portions on the outer surface thereof through which spot welding can be carried out from outside of the casing for securing said compressor unit to said casing with a reduced amount of heat from the welded portions, and
- said reduced thickness portion projecting inwardly from said casing to form a clearance in an axial direction of said casing between the projected surface of said reduced thickness portion and the outer surface of said compressor unit.
- 2. The hermetic type compressor according to claim 1 wherein said reduced thickness portion has a frusto-conical shape on the outer surface thereof.
- 3. The hermetic type compressor as set forth in claim 1 wherein the depth of said clearance grooves is selected to be larger than the height of said projections.
