Title:
VALVE TIMING CONTROLLER, ENGINE DEVICE HAVING THE SAME, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2006/064707
Kind Code:
A1
Abstract:
A valve timing controller, an engine device having the valve timing controller, and a vehicle. In the valve timing controller, when the speed of an engine is low, a force by a spring energizing a low speed lock pin in a direction for inserting the low speed lock pin into a low speed pin lead-in hole becomes larger than a centrifugal force acting on a weight. Accordingly, the low speed lock pin is inserted into the low speed pin lead-in hole, and the phase of an intake camshaft relative to an exhaust camshaft is fixed. When the speed of the engine is high, a force by the centrifugal force acting on the weight energizing the high speed lock pin in a direction for inserting the high speed lock pin into a high speed pin lead-in hole becomes larger than a force by the spring energizing the high speed lock pin in a direction for extracting the high speed lock pin from the high speed pin lead-in hole. Thus, the high speed lock pin can be inserted into the high speed pin lead-in hole, and the phase of the intake camshaft relative to the exhaust camshaft can be fixed.
