Abstract:
1. A control valve apparatus for a vehicle having a hydraulic system equipped with a main flow passage for feeding oil, discharged from an oil pump driven by an internal combustion engine, to each of lubricated engine parts, a branch passage branched from the main flow passage at a branched point, and a hydraulically-operated variable valve timing control device operated by a hydraulic pressure in the branch passage and having a lock mechanism configured to hold engine valve timing until the hydraulic pressure in the branch passage becomes greater than or equal to a specified pressure value, the control valve apparatus comprising: a spool valve configured to throttle the flow rate of the oil flowing through the portion of the main flow passage downstream of the branched point depending on an axial position of its spool, the axial position of the spool being obtained as a result of a sliding motion of the spool relative to a spool valve body, wherein
