Abstract: A modular control mechanism for shifting the phase of a camshaft relative to a crankshaft in an internal combustion engine, accomplished by shifting the angular position of the camshaft relative to the crankshaft. The mechanism comprising two hydraulic cylindrical housings attached to either the camshaft flange or the camshaft driving sprocket, and plungers within the cylindrical housings attached to the other flange to form a rotational hydraulic coupling. The hydraulic cylinders providing a pair of cavities which vary in displacement as the two flanges are rotated relative to one another. A control apparatus regulating the flow of fluid between the hydraulic cylindrical housings, thus controlling the phase shift between the crankshaft and camshaft. The control device using the energy produced by the reaction torque pulses on the camshaft, and resultant pressure pulses in the cavities, thus creating a self-actuating system. The control apparatus consisting of one of three alternate means for precisely controlling the flow of fluid, thus allowing for a modulated self-actuating mechanism.

Abstract: The invention relates to a gear device for a motor vehicle, as is used, for example, for adjusting a camshaft in a combustion engine in order to influence the phase angle between crankshaft and camshaft. Such gear devices have to be constructed compactly and also have to have high resistance to wear, in particular upon reaching end stops during adjustment of the phase angle. For this purpose, the gear device has hydraulic end stop damping by the drive unit and the output unit having communicating cavities.

Abstract: An engine variable camshaft timing (VCT) phaser assembly is equipped in an internal combustion engine (ICE) to adjust the rotation of the engine's camshaft relative to the engine's crankshaft. The adjustments advance and retard the opening and closing movements of the engine's intake and exhaust valves. An electric motor and a planetary gear set work together amid use of the VCT phaser assembly. The planetary gear set can include two or more ring gears, planet gears, and a sun gear. A backlash condition sometimes experienced in previous VCTs is minimized in the VCT phaser assembly by one or more springs that urge the planet gears into engagement with the ring gears.
