Claim:
1. A camshaft phase adjuster assembly comprising: a camshaft including a sprocket support portion, a bore extending axially in the sprocket support portion, and at least one helical groove extending between the bore and a radially outer surface of the sprocket support portion, the at least one helical groove includes circumferentially offset first and second ends; a drive sprocket including an opening that is supported on the sprocket support portion of the camshaft and 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 pin including a first end and a second end, the first end is arranged within the bore of the camshaft and includes at least one radially extending rotation pin, the radially extending rotation pin is engaged with the at least one helical groove and the at least one drive sprocket groove; and an actuator connected to the second end of the actuator pin that selectively moves the actuator pin axially within the bore of the camshaft such that the at least one radially extending rotation pin slides within the at least one helical groove and the at least one drive sprocket groove from (1) a first position in which the camshaft and the drive sprocket are located relative to each other in a first phase position, to (2) a second position in which the camshaft and the drive sprocket are rotated relative to each other to a second phase position.
