- それぞれシリンダ内の燃焼室と吸気装置および排気装置との間における接続を制御する少なくとも1個の吸気弁(12)および少なくとも1個の排気弁を有する内燃機関において弁動作を制御する装置であって、上り勾配(10a)と下り勾配(10b)とからなるカム曲線を有する回転カムシャフトは、弁ばね(13)の作用下において弁機構(14)と相互作用して前記吸気または排気弁(12)を動作させるように設計され、前記弁機構(14)は、前記吸気弁(12)または前記排気弁の閉弁段階において、前記カム曲線の前記下り勾配(10b)から独立して動作するように前記弁機構の閉弁動作を制御することを可能にする制御部材からなり、前記制御部材は、前記吸気弁または排気弁(12)の閉鎖が、前記弁ばねの閉弁力に対抗する油圧調節可能な力によって調節可能な期間にわたって遅らされうるように構成される装置において、
前記制御部材(21〜25、26)は、前記吸気弁または排気弁(12)の閉弁方向の移動を所定時間阻止する作動状態を実現できるようになっており、該制御部材(21〜25、26)は、前記吸気弁または排気弁(12)が開弁位置から閉弁動作中に作動状態から非作動状態に切り換わる動作と、最も早期に閉弁させるときには、非作動状態にして弁動作を前記カム曲線に従わせる動作とを行えるようになっていることを特徴とする装置。 - 前記弁(12)は、前記カム曲線の前記上り勾配(10a)により機械的に作動せしめられ、前記制御部材(21〜25、26)に接続される油圧回路は、前記弁機構(14)が前記上り勾配に従っているときに油圧油を制御部材へと流動させ、一旦前記上り勾配が通過されてしまうと、前記制御部材からのリターンフローを阻止することが可能であることを特徴とする請求項1に記載の装置。
- 前記制御部材(21〜25、26)は、前記弁(12)が最大開弁位置の領域内にあるときに作動から非作動状態に切り換わって弁閉弁動作を作動させるように設計されることを特徴とする請求項1または2に記載の装置。
- 前記弁(12)は、該弁が弁座に着座する前に、その閉弁速度を低下させる装置を備えることを特徴とする請求項3に記載の装置。
- 前記制御部材(21〜25、26)は、前記弁(12)に機械的に接続されるとともに油圧弁(26)によって作動せしめられうる油圧ピストンシリンダ(21〜25)からなることを特徴とする請求項1から4のいずれか1項に記載の装置。
- 前記制御部材(21〜25、26)は、前記エンジン排気弁(12)に適用されて内部排気再循環が行なわれることを特徴とする請求項1から5いずれか1項に記載の装置。
- 前記制御部材(21〜25、26)は、前記エンジン吸気弁(12)に適用されて閉弁シーケンスを変化させることを特徴とする請求項1から5のいずれか1項に記載の装置。
