Abstract

PURPOSE: To obtain a smaller-sized oil pump having no lack of oil flow by a method wherein the waste oil after a capacity-regulating piston has been driven is supplied for the purpose of cooling of compressed gas and lubrication into a rotor in which coolant gas has been sealed.
CONSTITUTION: The waste oil after a capacity regulating piston 5 has been driven is supplied through a waste oil pipe 14 into a rotor 2 after coolant gas has been sealed for cooling of compressed gas and lubrication. In other words, injection oil supply is carried out by the waste oil in a stage capacity regulating mechanism. At this time, if the diameters of electromagnetic valves 9, 10, 11 are made larger in the figure, the flow rate is not short. Thus, the capacity of the oil pump can be made smaller and cost is reduced. The waste oil is sealed or forced in after completion of suction and is free from suction efficiency, excessive oil is not compressed. The performance can be improved.
