Abstract:
A blow-by gas reduction device includes: a gas return pipe, one end of which is connected to an engine and the other end of which is connected to an intake pipe, to return a blow-by gas in the engine to an intake side; an oil separator that is connected to the gas return pipe; an oil return pipe that is connected to the oil separator and is disposed with an inclination so as to return the oil to an inside of the engine; and a check valve that is provided in the oil return pipe, wherein the oil return pipe between the oil separator and the check valve is formed such that that the oil return pipe located at the check valve side is located at a lower side everywhere as compared with the oil return pipe located at the oil separator side.

Claim (Index 1):
A blow-by gas reduction device comprising:\n a gas return pipe, one end of which is connected to an engine and the other end of which is connected to an intake pipe, to return a blow-by gas in the engine to an intake side; an oil separator that is connected to the gas return pipe to separate oil contained in the blow-by gas; an oil return pipe that is connected to the oil separator and is disposed with an inclination so as to return the oil to an inside of the engine; and a check valve that is provided in the oil return pipe, wherein when an internal pressure of a crankcase in the engine exceeds an atmospheric pressure, the check valve is closed, wherein the oil return pipe between the oil separator and the check valve is formed with the inclination such that the oil return pipe located at the check valve side is located at a lower side everywhere as compared with the oil return pipe located at the oil separator side.
