Abstract: A forward phase of a forward intermediate rotor is adjusted relative to a crank shaft. A forward stopper mechanism prevents further advance of the forward phase by engaging the forward intermediate rotor at a forward most-advanced phase. A forward locking mechanism locks the forward phase when reaching the forward most-advanced phase at a start time of the engine. A forward biasing member biases the forward intermediate rotor in an advance direction. The backward phase of the intake cam shaft is adjusted relative to a backward intermediate rotor by receiving a cam torque that is biased on average in a retard direction. A backward stopper mechanism prevents further retard of the backward phase by engaging the intake cam shaft at a backward most-retarded phase. A backward locking mechanism locks the backward phase when reaching the backward most-retarded phase at the start time of the engine.

Abstract translation: 正向中间转子的前进相位相对于曲柄轴进行调节。 前挡块机构通过以前进最前进的相位接合前进中间转子来防止前进相的进一步前进。 前进锁定机构在发动机起动时到达前进最前进阶段时锁定前进相。 前向偏压构件沿前进方向偏压前进中间转子。 通过接收在延迟方向上平均偏置的凸轮转矩，相对于后退中间转子调节进气凸轮轴的后退相位。 后挡块机构通过使进气凸轮轴在后退最大延迟阶段接合来防止后退相位的进一步延迟。 后向锁定机构在发动机起动时到达后退最大相位时锁定后退相位。
