介装したことを特徴とする内燃機関の吸気弁。 A valve head is formed at the tip of the valve stem that penetrates into the intake port. When the valve is closed, the valve stem is pulled up and the valve head is seated on the valve seat formed at the outlet of the intake port. When the valve is opened, the valve stem is pushed down and the valve head is seated. In an internal combustion engine intake valve that allows intake air to flow into the combustion chamber through a gap between the valve seat and the valve seat, a passage is formed inside the valve head that communicates the intake port with the combustion chamber. An intake valve for an internal combustion engine, characterized in that it is equipped with a check valve that opens only when the pressure exceeds .
