Title:
DEVICE AND METHOD FOR CONTROLLING VALVE TIMING ADJUSTMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/167135
Kind Code:
A1
Abstract:
In the present invention, an ECU (101) supplies lock pin-releasing hydraulic pressure to an advance-angle lock pin-releasing oil passage (5a) to release engagement of an advance-angle lock pin (6) from an advance-angle engagement groove (9), places a rotor (1) in a state of being able to rotate to an advance-angle side, and creates a gap between the advance-angle engagement groove (9) and the advance-angle lock pin (6), for establishing communication to a delay-angle lock pin-releasing oil passage (5c). Next, the ECU (101) supplies hydraulic pressure to an advance-angle hydraulic chamber (16) to cause the rotor (1) to rotate, and supplies lock pin-releasing hydraulic pressure to a delay-angle engagement groove (10) by way of the gap and the delay-angle lock pin-releasing oil passage (5c) to release engagement of a delay-angle lock pin (7).
