Abstract
PURPOSE: To prevent the temperature rise of lubicating oil, under no load operating condition obtained by means of a load reducing device, by returning the surplus oil with the pressure above a predetermined value which is supplied by No.1 pump into the internal passage of a flow regulator valve and contracted.
CONSTITUTION: When compressor 11 and 21 operate at no load because compression-chamber suction ports 14 and 24 are closed by a load reducing device 31, lubricating oil is sucked by No.1 pump 2 from a tank 5 through a cooler 9 and a passage 42, and is discharged into a passage 40 and supplied to a flow regulator valve 8. When the liquid pressure rises in the passage 40 by contracting the internal passage of the flow regulator valve 8, a relief valve 50 is actuated and surplus oil at the pressure above a predetermined value is discharged and returned in the upstream side of a tank 5 or the cooler 9 through a passage 48. Therefore, even under lightload or no-load operating condition, the same quantity oil as that of full load circulates through the tank 5, the cooler 9, and the passage 42, thus the oil temperature rise can be prevented.
