    Abstract: A camshaft adjuster for an internal combustion engine having hydraulic medium guides. The adjuster can include a setting unit that can be controlled by a control unit using these guides in the adjuster, wherein the setting unit is for adjusting an angle of a camshaft. This setting unit has an inner body coupled to the camshaft so as to rotate with it, and an outer body that is mounted to rotate relative to the camshaft via a drive connection which runs from a crankshaft to the camshaft. The camshaft has at least one insert part permanently inserted camshaft wherein these two components together form at least one hydraulic medium guide at least in partial regions over its axial length. This design is to create a camshaft adjuster which is in interaction with a camshaft having an insert part so that there is a simple and reliable supply of hydraulic medium to the camshaft adjuster and in particular to its control device.

    Abstract: A variable timing camshaft drive assembly for an internal combustion engine utilizes a single cam phaser, driven by an engine crankshaft, capable of operating multiple camshafts carried on multiple banks of an engine. The cam phaser is carried on a hub extending from a mounting member attached to an engine block. The cam phaser includes an input sprocket and an output sprocket separated by a phasing device capable of altering the phase angle of the sprockets relative to one another. A first timing chain connects a drive sprocket of the crankshaft with the input sprocket of the cam phaser and a second timing chain connects the output sprocket of the cam phaser with the driven sprockets of the camshafts. As the phasing device alters the phase angle between the input and output sprockets, the phase angle between the camshafts and the crankshafts is altered.

    Abstract: A variable valve timing control system of an internal combustion engine includes a hydraulically-operated phase converter disposed between a sprocket and a camshaft, and having a phase-advance hydraulic chamber and a phase-retard hydraulic chamber for changing an angular phase of the camshaft relative to the sprocket. An electric pump is provided to supply working fluid selectively to one of the hydraulic chambers via a directional control valve. Also provided is a check valve disposed in a discharge line of the pump for permitting flow in a direction that the working fluid flows from the pump to the directional control valve and preventing any flow in the opposite direction, so as to prevent a pulse pressure arising from alternating torque exerted on the camshaft from being transmitted from either one of the hydraulic chambers via the discharge line to a discharge port of the pump.
