を特徴とするエンジンの吸気制御弁。 In an engine intake control valve in which a plurality of valve plates for simultaneously opening and closing each intake passage are attached to a single valve shaft disposed across a plurality of intake passages provided in one body, the valve plate is formed in a shape that completely closes the intake passage with an inclined surface equal to the fully closing angle when the valve stem is curved toward the downstream side of the intake passage, and the valve plate is formed in a shape that completely closes the intake passage when the valve stem is in a straight state at room temperature. It is noted that the peripheral edge of the end of the valve shaft is substantially in contact with the end of the body of the intake passage wall, and the peripheral edge of the central part of the valve shaft is attached to the valve shaft with a gap between the peripheral edge of the valve shaft and the central body of the intake passage wall. Characteristic engine intake control valve.
