Abstract
A V-type internal combustion engine comprises a plurality of hydraulically actuable valve operation mode control actuators for two cylinder banks. A hydraulic fluid network is fluidly disposed between a main gallery of the cylinder block and the plurality of hydraulically actuable valve operation mode control actuators and includes a single control valve. The single control valve is common to all of the plurality of hydraulically actuable valve operation mode control actuators. This control valve is attached to a casing adapted to receive a drive system connecting the engine camshafts to the engine crankshaft. This casing has internal passages forming a part of the hydraulic fluid network between the control valve and the plurality of hydraulically actuable valve operation mode control actuators.
