Abstract
A valve timing control having a stator body constructed of a plastic material. The stator body has an annular side wall and a front plate which, together, define a plurality of annularly spaced internal cavities within the stator body. A rotor having a plurality of vanes is positioned within the stator body so that one vane is positioned within each cavity. The rotor is movable relative to the stator body between a first and second rotational position. A plurality of threaded metal inserts are embedded within the stator body and used to attach a metal sprocket to the stator body at a position opposed to the front plate. Two of these inserts also receive the impact load from the rotor.
