Abstract

PURPOSE:To prevent the leakage of a coolant in a rotary compressor provided with movable vanes, by setting such a clearance between each end face of the vane and a side plate that no seizure occurs and by supplying lubricating oil to the clearance. CONSTITUTION:Lubricating oil pressurized by discharged gas is supplied from a ring groove 17 to a hind opening 18 and enters into a communication hole 14. The lubricating oil whose flow rate is restricted by a thin tube 15 is supplied to a pocket 13 to produce an oil film in a clearance (d). Since the lubricating oil whose flow rate is restricted by the thin tube 15 is supplied, vanes serve as static pressure bearings in which the end faces 8 of the vanes are supported without contact. The larger the clearance (d) is, the lower the load carrying capacity of the bearings is. But, the smaller the clearance (d) is, the higher the carrying capacity is. The oil film produced in the clearance (d) enables not only the reduction of coolant leakage but also the increase in the clearance (d). This results in improving lubricating conditions and in preventing seizure during high-speed running.
