Valve timing adjusting device |
摘要 |
A valve timing adjusting device adjusts valve timing by shifting rotational phase of a camshaft relative to a crankshaft. The device has an electric motor for rotating a rotor member that drives and moves a phase defining member to a required position. The phase defining member defines the rotational phase of the camshaft in accordance with the position itself. The phase defining member may be a planetary gear rotatably supported on an eccentric shaft as the rotor member. The planetary gear works as both a reduction mechanism and a phase shifting mechanism. The phase defining member may be a control pin slidably supported on a rotatable member as the rotor member. A planetary gear may be additionally used as the reduction mechanism for rotating the rotatable member. It is possible to control the phase with high accuracy and durability.
