Abstract
PURPOSE: To keep a pressure at a set value by providing a by-pass line between an aftercooler and an oil separator to make a by-passing of an air amount, which is the same as that of the air which flows out from a discharge opening of a suction unloader, from the aftercooler to the oil separator.
CONSTITUTION: The air inside an oil separator 9 is discharged through a pressure regulating valve 12 by opening a solenoid valve 16 at the time of an unloading till the pressure reaches a preset value of the pressure regulating valve 12. Since a by- pass piping to which a pressure regulating valve 20 and a nozzle 19 are attached, is provided between an aftercooler 10 and the oil separator 9, the air amounts the same as that which flows out to an environment through a discharging opening 11 from a cylinder of a suction unloader 6 and is by-passed from the after-cooler 10 to the oil separator 9. Thus, the pressure at the oil separator can be kept at the preset value of the regulating valve 12, and also, the oil feeding to the bearing can be performed with much more sureness.
