Abstract
On the assumption that pressure Pm (MPa) of a boss portion outside space determined by a restrictor and a flow regulating valve provided midway in an oil feed passageway is expressed by Pm =Ps+&agr;, and a differential pressure value at which a difference between high and low pressures becomes minimum in a running pressure range of a scroll compressor is represented by min(Pd−Ps), the value a in the above expression is set to fall in a range expressed by 0<&agr;<min(Pd−Ps). Here, Ps represents suction pressure (MPa) of the compressor, and Pd represents discharge pressure (MPa) of the compressor.
