ABSTRACT:
A hydraulic valve assembly is provided to activate and deactivate cylinder valves of a multi-cylinder engine. A plurality of electrohydraulic valves are loosely received in openings in a base plate which allows the relative positions of the valve to adjust automatically for dimensional irregularities as the assembly is installed on the engine. At the complete of that installation, elements of each electrohydraulic valve are clamped between the base plate and the engine to secure the valves in position. A flexible lead frame containing electrical conductors is secured to both the base plate and the electrohydraulic valves provides additional support while allowing movement of the valves with respect to the base plate.
