装置。In a blowby gas reduction device for an internal combustion engine, the blowby gas accumulated in the crankcase or rocker cover is returned to the intake pipe via a pressure regulating valve that adjusts the pressure in the crankcase, and then guided to the combustion chamber through the intake pipe. ,
The pressure regulating valve includes an inflow port and an outflow port for blow-by gas, and the inflow port and the outflow port are communicated with each other by a seal valve that opens and closes based on fluctuations in the pressure inside the crankcase. An oil separation chamber is provided between the inflow port and the outflow port to reduce the flow rate of the blowby gas and separate the oil component in the blowby gas, and a small hole is provided in the seat of the separation chamber to discharge the oil into the engine. A blow-by gas reduction device for an internal combustion engine, characterized by:
