Abstract
A camshaft phase adjuster assembly is provided that includes at least one helical groove for adjusting a phase position between a camshaft and a drive sprocket. The camshaft phase adjuster assembly includes a camshaft including at least one helical groove extending between a bore and a radially outer surface of a sprocket support portion, and the helical groove includes circumferentially offset first and second ends. A drive sprocket includes at least one axially extending drive sprocket groove on a radially inner surface of the drive sprocket arranged facing the at least one helical groove. An actuator selectively moves an actuator pin axially such that a radially extending rotation pin slides within the helical groove and the drive sprocket groove from a first phase position to a second phase position.
