Description
背圧油路は、チェック弁部の外部を経由して前記空間と流出口とを連通するよう形成されている。
第1実施形態のバルブタイミング調整装置およびその一部を図1~7に示す。バルブタイミング調整装置10は、例えば車両に搭載され、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実施形態によるバルブタイミング調整装置の一部を図6に示す。第2実施形態は、スリーブ72の構成等が第1実施形態と異なる。
第3実施形態によるバルブタイミング調整装置の一部を図9に示す。第3実施形態は、チェック弁部70の構成等が第1実施形態と異なる。
第4実施形態によるバルブタイミング調整装置の一部を図11に示す。第4実施形態は、スリーブ72の構成等が第2実施形態と異なる。
第5実施形態によるバルブタイミング調整装置の一部を図12に示す。第5実施形態は、スリーブ72の構成等が第4実施形態と異なる。
上述の実施形態では、流出口としての横穴部75が、流入口としての弁座穴部712の軸Ax1に対し軸Ax2が直交するよう形成される例を示した。これに対し、他の実施形態では、流出口としての横穴部75は、流入口としての弁座穴部712の軸Ax1に対し軸Ax2が傾斜して交差するよう形成されていてもよい。また、流出口としての横穴部75は、流入口としての弁座穴部712の軸Ax1に対し軸Ax2が捩れの関係となるよう形成されていてもよい。
