Abstract
A lifter oil manifold assembly for variable actuation of engine valves having first (top) and second (valve) plates having portions of oil control and oil exhaust passages formed therein. The assembly further includes a carrier member having an oil supply passage integrated thereby separating the oil supply path from the oil control and oil exhaust path. Further, the assembly includes towers for receiving and positioning the electro-magnetic oil control valves used to control oil flow in the assembly. The towers are molded separate from the carrier and are held in place by the valve plate or are molded integral with the carrier. In another aspect of the invention, oil control valve retention springs are molded integral with either the tower or the oil control valve. In a further aspect of the invention, a combined polymer restrictor/strainer in the oil circuit replaces a prior art metal die-cast restrictor.
