ABSTRACT:
A fluid inletting system for a hydaulically actuated variable valve selection assembly for an engine valve train of an engine cylinder head with dual camshafts and two valves associated with each camshaft per cylinder. The latching mechanisms associated with the rocker arms are activated by pressurized engine lubricating oil which is introduced to the interior of the tubular support shaft for application against the end of the cylindrical portion of the latching member. The support shafts for each cylinder are supported by bosses of the cylinder head and aligned end to end with thin washer or spacer members between the ends of adjacent shafts to define separate oil passages in two adjacent shafts.
