Abstract:
A valve timing adjuster adjusts timing of opening and closing an intake valve or an exhaust valve by changing a phase between a drive shaft and a driven shaft. The valve timing adjuster includes a housing, a vane rotor, an urging member, a regulating member, and a control unit. The control unit controls rotation of an electric motor that rotates the drive shaft. When an internal combustion engine stops in a state, where the regulating member is positioned out of a bore, the control unit restarts the engine by controlling the electric motor in the following manner. Firstly, the motor is controlled to rotate at a first rotational speed, which is a relatively high speed and subsequently, the motor is quickly changed to rotate at a second rotational speed, which is a relatively low speed.
