摘要: In a rotary compressor of a vane rotary type, an outer peripheral surface of an eccentric portion of a shaft on a side adjacent to a center of the shaft is located radially inwardly of an outer peripheral surface of a main shaft inserted in a main bearing and that of an auxiliary shaft inserted in an auxiliary bearing. Also, a back clearance means used in mounting a piston on the shaft is provided in each of an inner peripheral surface of the piston and the eccentric portion of the shaft. Such configurations can reduce a diameter of the eccentric portion. A reduction in diameter of the eccentric portion can reduce a viscous force of oil acting between the eccentric portion of the shaft and the inner peripheral surface of the piston to thereby reduce a rotational moment about a center of the eccentric portion of the shaft, which rotational moment acts on the piston in a direction of rotation of the shaft, thus making it possible to reduce a sliding loss that is generated by a reciprocating motion of a vane in a vane groove.

摘要: An object of the present invention is to provide a refrigeration cycle apparatus having a compressor that is not easily heated to high temperature by sliding heat and thus higher in reliability.Provided is a refrigeration cycle apparatus having a cost-effective compressor in the configuration in which a piston 9 eccentrically revolving, as driven by a shaft 4, is placed in a cylinder 6 and the circular terminal region 10a of a vane 10 partitioning the cylinder 6 into a suction chamber 12 and a compression chamber 13 is connected slidably to the external surface of the piston 9 in surface contact, which can reduce the sliding heat and is thus resistant to deterioration in reliability by reaction of the operating refrigerant.

摘要: A refrigerant being low in both ODP and GWP and containing at least hydrofluoroolefin having a double bond of carbon is used. By providing a first compression-chamber oil feed path for feeding refrigerating machine oil to a compression chamber 15 after the refrigerant has been enclosed therein, effects on the global environment can be suppressed and moreover temperature increases of the refrigerant due to re-expansion heating and feeding of high-temperature refrigerating machine oil can be suppressed, i.e., decomposition of the refrigerant can be inhibited.
