PURPOSE:To prevent environmental pollution due to lubricating oil in the air by disposing a lubricating oil recovery device in a lubricating oil tank to naturally recover vapor lubricating oil in the lubricating oil tank. CONSTITUTION:Lubricating oil is circled at high speed to work centrifugal force upon the vapor lubricating oil, so that lubricating oil component heavier than air is mostly adhered to the inner wall surface of a recovery device 23. While air partially containing lubricating oil is discharged in exhaust gas as a vent 27, the lubricating oil contained in the vent 27 burns because the temperature of the exhaust gas is high, so that lubricating oil is kept from being discharged to the air to prevent environmental pollution. |
