Abstract
In a gas-liquid separation device for an internal combustion engine used in an outboard motor, comprising: a gas-liquid separation chamber defined in a part of the engine, the chamber being provided with first and second ports communicating with a crankcase, and a third port communicating with an intake passage, the first port is provided with a first one-way valve for allowing blow-by gas from the crankcase to flow into the chamber, and the second port is provided with a second one-way valve for allowing oil separated from the blow-by gas to be discharged from the chamber, wherein the second one-way valve includes a reed valve member adapted to selectively close the second port, and a valve seat defined by an annular surface which is elevated from a surface of a wall surrounding the second port and defines a larger opening area than the second port.
