Electro-hydraulic manifold assembly and method of making same for controlling de-activation of combustion chamber valves in a multicylinder engine
A solenoid valve and manifold assembly for installation on an engine and connecting with hydraulic circuits in the engine for de-actuating the combustion chamber valves of selected cylinders of the engine. A manifold deck is formed with the valving channels and ports therein for connecting to the hydraulic circuits. A gasket is formed with solenoid valve mounting bosses and valving passages as a unitary member and is retained on the manifold deck by a retaining plate preferably stamped from sheet stock with clearance holes received over the valve mounting bosses and secured to the manifold deck over the gasket for sealing the gasket thereon. The valves are inserted in the bosses and retained by a preferably stamped bracket and the bracket, retaining plate and gasket secured to the manifold deck by common fasteners. A common electrical lead frame is received over the valve terminals for making electrical connection to the valves. The assembly of valves and the manifold deck may then be attached to the engine as a unit.
