US 5,950,452 A · Rotary compressor and refrigerating apparatus

Abstract

A blade 8 is integrally fixed to a roller 7 mounted around an eccentric section 22 of a drive shaft 21. The blade 8 extend radially outwardly of the roller 7, and partitions the inside of a cylinder chamber 41 into a compression chamber X and a suction chamber Y. A protruded end portion of the blade 8 is received in a reception groove 11a of a support member 11 which is pivotally supported by a stationary member 4. A substitute fleon refrigerant is used as a working fluid in the cylinder chamber 41, and an oil adapted to the substitute fleon refrigerant is used as a lubricating oil for a compressor CP. While using the substitute fleon refrigerant, the deterioration of the oil in the compressor is prevented.

A rotary compressor comprising:

a roller rotatably mounted around an eccentric section of a drive shaft;
a blade which is integrally fixed on a periphery of the roller and extends radially outwardly of the roller, thereby partitioning a cylinder chamber inside a cylinder into a compression chamber and a suction chamber;
and
a support member which is pivotally supported by the cylinder and is formed with a reception groove for receiving a guiding therein a protruded end portion of the blade, wherein
a refrigerant which does not include chlorine within its basic chemical composition is used as a working fluid to be supplied to and discharged from the inside of said cylinder chamber, and
an oil adapted to the refrigerant is used as a lubricating oil.
