Description

ABSTRACT:
A valve timing control device for an internal combustion engine includes an intermediate rotary component disposed between an input component which is driven in synchronism with an engine revolution, and a cam drive component which is rigidly connected to a camshaft. The intermediate component is variable of positions relative to the input and cam drive components in order to adjust phase relationship between the input component and the cam drive component for setting valve timing at optimal timing relative to engine revolution cycle. The device includes a hydraulic means which selectively locks the intermediate component at a selected position where optimal phase relationship relative to the engine driving condition is established.
