弁とを有するブローバイガス還元装置用気液分離装置。A gas-liquid separation filter element is provided in a gas-liquid separation chamber defined by a baffle plate in the cylinder head cover to partition the gas-liquid separation chamber into a first compartment and a second compartment; In the gas-liquid separation device for a blow-by gas reduction device of an internal combustion engine, the first compartment is in communication with a valve train chamber in the cylinder head force bar, and the second compartment is in communication with a blow-by gas take-off port. The second compartment is divided into an upper chamber that includes the gas-liquid separation filter element and the blow-by gas take-out port, and a lower chamber that does not include the blow-by gas/take-out port, and the upper chamber and the lower chamber are communicated with each other. an oil return port provided at the bottom of the lower chamber and opened toward the valve operating chamber; and an oil return port provided at the oil return port to allow communication from the lower chamber to the valve operating chamber. A check valve that only allows fluid to flow toward the chamber, a vent hole that allows the lower chamber and the valve operating chamber to communicate with each other, and a flow that closes the communication port only when the amount of oil in the lower chamber is equal to or higher than a predetermined value. 1・
A gas-liquid separation device for a blow-by gas reduction device having a valve.
