Claims (1)
成すると共に、エンジンの低負荷時に閉じ且つ高
負荷時に開く制御弁を上記２次吸気通路に配設し
たエンジンの吸気装置であつて、上記吸気通路に
発生する吸気負圧が第１設定負圧よりも大きい時
に上記制御弁を閉方向に動作させる負圧作動式ア
クチユエータと、該アクチユエータによる上記制
御弁の閉方向の動作を弾性部材の弾性力によつて
所定開度で規制する係止部とが備えられていると
共に、上記弾性部材は、上記吸気負圧が上記第１
設定負圧よりも大きな第２設定負圧を超えた時に
、上記制御弁を上記所定開度から閉方向に動作さ
せるようにその弾性力が設定されていることを特
徴とするエンジンの吸気装置。 An intake system for an engine, wherein the intake passage is constituted by a primary intake passage and a secondary intake passage, and a control valve that closes when the engine is under low load and opens when the engine has a high load is disposed in the secondary intake passage, a negative pressure operated actuator that operates the control valve in the closing direction when the intake negative pressure generated in the intake passage is greater than a first set negative pressure; and an elastic member that controls the actuator to operate the control valve in the closing direction. The elastic member is provided with a locking portion that regulates the opening at a predetermined opening degree by force, and the elastic member is configured such that the intake negative pressure is controlled by the first opening.
An intake system for an engine, wherein the elastic force of the control valve is set so as to operate the control valve from the predetermined opening degree in the closing direction when a second set negative pressure that is larger than the set negative pressure is exceeded.
