Publication number: 20200292035Abstract: A vane phaser with an unlocking and relocking mechanism attached to the lock pin, which through the use of a solenoid, distinct from the solenoid used for the oil control valve, which can lock and unlock the vane phaser. When the solenoid is energized and during rotation of the camshaft, the solenoid makes contact with a lever or gear wheel attached to the lock pin, causing the lock pin to rotate. A helical feature on the lock pin itself or on the lever causes the lock pin to move axially, unlocking the vane phaser.Type: ApplicationFiled: May 29, 2020Publication date: September 17, 2020Inventors: Mark M. Wigsten, Jonas Adler
