Abstract
PURPOSE:To restrain the temperature of fed oil from exceeding a predetermined value even though the discharge pressure is lowered, by detecting the pressure in a discharge passage in a compressor body so that the opening degree of a flow passage of three-way selector valve passing through an oil cooler is increased when the discharge pressure is less than a set value. CONSTITUTION:An oil reclaimer 2 provided in a discharge passage 2 form a compressor body 1 is communicated with an oil pump 8 through an oil supply passage 9 by way of a three-way selector valve 4 and a passage and by way of a flow passage 7 in which an oil cooler 6 is disposed. Further, the temperature controller 10 is disposed in the discharge passage 2. In this arrangement, a three-way selector valve 12 and a supply pressure setting unit 13 are disposed in an air supply passage 11. Further, a pressure switch 14 is disposed in the discharge passage 2. Further, when the discharge pressure is lower than a set value, an air pressure serving as a control signal is changed over so that the opening degree of the flow passage 7 passing through the oil cooler in the three-way selector valve 4 is made to be large.
