1. The figure shows the relative operation structures of the housing vane to the rotor vane.
2. If the CVVT is held a certain control angle, to hold this state, oil is replenished as much as oil leaks from the oil pump.
The OCV (Oil-flow Control Valve) spool location at this time is as follows.
Oil pump -> Advance oil chamber (Little by little open the inflow side to the advance oil chamber) -> Almost close the drain side
Be sure there might be a difference in the position according to the engine running state (rpm, oil temperature, and oil pressure).
