Abstract
PURPOSE: To prevent excessive lowering of temperature of oil circulating between a compressor main body and an oil separator as well as generation of drainages, by controlling an opening area of a vent hole provided in a package so as to lower the volume of wind passing through the package.
CONSTITUTION: In idling run of a compressor 1, a pressure switch 15 is closed, a solenoid valve 13 is opened and air released from an oil separator 7 is supplied through a branch piping 53 to a chamber F of a gas actuator 44. In response to this, a piston 47 shifts against springs 52A, 52B and a door 49 throttles a vent hole 42 to a suitable area of a flow passage. Thereby, the inflow volume of the outside air into a package 39 decreases. Accordingly, the compressor 1 comes to idling and even if its radiant heat volume is large, a cooling effect by the outside air flowing through the package 39 is controlled to be small, so that excessive lowering of temperature of oil may be prevented as well as generation of drainages.
