Description
第1実施形態による弁装置、および、それを用いたバルブタイミング調整装置を図1、2に示す。バルブタイミング調整装置10は、内燃機関としてのエンジン1のクランク軸2に対するカム軸3の回転位相を変化させることによって、カム軸3が開閉駆動する吸気弁4または排気弁5のうち吸気弁4のバルブタイミングを調整するものである。バルブタイミング調整装置10は、クランク軸2からカム軸3までの動力伝達経路に設けられている。クランク軸2は、「駆動軸」に対応する。カム軸3は、「従動軸」に対応する。吸気弁4、排気弁5は、「バルブ」に対応する。
第2実施形態による弁装置のチェック弁を図10に示す。第2実施形態は、遅角供給チェック弁71、進角供給チェック弁72の構成が第1実施形態と異なる。
第3実施形態による弁装置の一部を図11に示す。第3実施形態は、チェック弁および回転規制部の構成等が第1実施形態と異なる。なお、図11では、スプール60、スプリング63等の図示を省略している。
上述の実施形態では、回転規制部90が、幅広部721、幅広部722の少なくとも一部が環状溝部55の最大距離区間Sbd内に位置するよう弁本体700の回転位置を規制する例を示した。これに対し、本発明の他の実施形態では、回転規制部90は、幅広部721、幅広部722の全ての部位が、最大距離区間Sbd内に位置するよう弁本体700の回転位置を規制することとしてもよい。つまり、回転規制部90は、幅広部721、幅広部722が遅角環状溝部511の周方向において遅角供給開口部ORsと重ならないよう弁本体700の回転位置を規制することとしてもよい。この場合、幅広部721、幅広部722が環状溝部55から径方向内側すなわち内周壁54側へ飛び出るのをより効果的に抑制できる。
このように、本開示は、上記実施形態に限定されるものではなく、その要旨を逸脱しない範囲で種々の形態で実施可能である。
