The controlled hydraulic engine oil flow is directed through advance or retard activation oil ports. Each port exits into a sealed chamber on the opposite sides of a control piston.
In its default position the oil flow is directed to the rear surface of the piston. This pulls the helical gear forward and maintains the retarded valve timing position. When the oil flow is directed to the front surface of the piston, the oil pushesthe helical gear in the opposite direction which rotates the matched helical gearing connected to the camshaft.
