Abstract

【課題】　バルブクリアランスの増加・減少を自動的に調整すること。 【解決手段】　ねじ部２４、２６を有するハウジング１２と、ねじ部２４とねじ結合されたねじ部材１４と、ねじ部材１４に相互回転防止継ぎ手３２、３８を介して連結されて、ねじ部２６とねじ結合されたねじ部材１６と、ねじ部材１４、１６を互いに離れる方向に付勢する弾性部材１８と、ねじ部材１６を、ねじ部材１４に近づける方向の力で付勢する弾性部材２０を備え、ねじ部材１４に作用する荷重がバルブ閉荷重以下のときに、ねじ部材１４の滑りトルク＞ねじ部材１６の自立トルクで、ねじ部材１４、１６の一体回転によりバルブクリアランスを減少させ、ねじ部材１４に働く荷重が、バルブ開荷重近傍あるいは超えるときには、ねじ部材１４の滑りトルクの絶対値＞ねじ部材１６の自立トルクで、ねじ部材１４、１６の一体回転によりバルブクリアランスを増加させる。
