Claims (1)
- 機関のクランクシャフトによって回転駆動する回転体と、
カムシャフトの端部に固定されて、円環状の基部の外周側に複数の羽根部が一体に形成されたベーンと、
該ベーンを回転自在に収容したハウジングと、
該ハウジングの内周面に内方へ突設された複数の隔壁部と、
前記各羽根部に設けられ、前記ハウジングの内周面に摺接するように外方に押圧されるシール部材と、
前記隔壁部と前記各羽根部の両側面との間に画成された遅角側油圧室及び進角側油圧室と、
該両油圧室に相対的に油圧を給排して前記ベーンを正逆回転させる油路と、
該油路から供給される油圧が低い状態では、前記ベーンの回動位置を前記ハウジングに対して維持させるロック機構と、
を備えたバルブタイミング制御装置であって、
前記ベーンの前端面における摺動する面全体に潤滑剤をコーティングしたことを特徴とする内燃機関のバルブタイミング制御装置。
