Abstract

An electro-hydraulic manifold assembly for deactivation of the valves of one bank of cylinders in a V-10 engine. One solenoid valve controls flow of oil to the hydraulic valve lifter/lash adjuster of a single or first cylinder, a second valve controls flow of oil to the lifters/lash adjusters of cylinders two and five and a third valve controls oil flow to the lifters/lash adjusters for cylinders two and three by taking advantage of the common base circle position of the cams for the paired cylinders.
