Abstract: A split ring planetary drive for an engine or use with an electric phaser. The split ring planetary drive includes a sun gear, a plurality of planet gears, a spring ring gear, a camshaft ring gear, and at least one spring. The sun gear has teeth and is driven to rotate around a sun axis. The plurality of planet gears are arranged around the sun gear with each planet gear comprised of planet teeth maintaining the planet gear in meshing engagement with the sun gear teeth. The sprocket ring gear has teeth and is driven by a crankshaft. The camshaft ring gear has teeth is rotatable with a camshaft. The teeth of the sprocket and camshaft ring gears maintain the ring gears in meshing engagement with each of the planet gears. The spring biases the planet gear teeth into meshing engagement with the sprocket and camshaft ring gear teeth.

Abstract: A pressure regulator is in fluid communication with a supply inlet of a hydraulic tensioner to actively control fluid to the inlet of the hydraulic tensioner. By actively controlling the pressure regulator based on engine conditions and thus the oil pressure being fed to the hydraulic tensioner, the oil pressure to the hydraulic tensioner may be reduced at low engine speeds, increasing the efficiency of the timing system, or allowing full oil pressure at high engine speeds and low engine temperature.

At least one fluid piston pump (36, 36a, 36b) connected to the at least one cam lobe (52) for generating a reciprocating fluid flow in response to rotation of the at least one cam lobe (52). At least one hydraulically actuated valve (34a, 34b, 34c, 34d, 134a, 134b, 134c, 134d) in fluid communication with the reciprocal fluid flow generated by the at least one fluid piston pump (36, 36a, 36b) to drive the valve (34a, 34b, 34c, 34d, 134a, 134b, 134c, 134d) to be controlled toward an open position.

Abstract: An electric phaser for dynamically adjusting the phase of a camshaft relative to a crankshaft with a split ring planetary drive. The split ring planetary drive including: a sun gear driven by a motor, a plurality of planetary gears with stop teeth, a first ring gear driven by the crankshaft, and a second ring gear rotatable with the camshaft. Either the first or second ring gears each include a first and a second stop. When the stop teeth of the planetary gears interacts with the first stop or the second stop on either the first or second ring gears, rotation of the phaser further in the first direction or the second direction towards the first or second stops is halted.

Abstract: In an engine comprising a cylinder having first and second engine valves of a same function type, a system for actuating the first and second engine valves comprises a first and second master pistons that receive first and second valve actuation motions from respective ones of a first and second valve actuation motion source, a first slave piston operatively connected to the first engine valve and configured to hydraulically receive the first valve actuation motions from at least the first master piston and a second slave piston operatively connected to the second engine valve and configured to hydraulically receive the second valve actuation motions from the second master piston. The system further comprises an accumulator and a mode selector valve in hydraulic communication with the first master piston, the first slave piston and the accumulator. The mode selector valve may selectively hydraulically connect the first master piston to the accumulator.

Abstract: A valve operating system that includes a plurality of cam assemblies that are coupled for rotation about a rotary axis. Each of the cam assemblies has a control link and a first cam member. Each of the control links has a link body, which forms a majority of the control link, and that extends parallel to the rotary axis. Each of the first cam members is coupled to one of the control links for axial movement therewith along the rotary axis between first and second positions to alternate between first and second cam profiles, respectively.

Abstract: A tensioner (10) for an endless loop power transmission member can induce a piston (12) operably engageable with an endless loop power transmission member, and a cylinder (14) guiding include a piston (12) for sliding coaxial movement in a direction of the endless loop power transmission member. The piston (12) and cylinder (14) defining an oil reservoir or pressure chamber (26) for receiving hydraulic fluid. A bearing (28) has bearing balls (30) located in a counter bore (32) coaxil with cylinder bore (34). The counter bore (32) has a steep taper (36) on which the bearing balls (30) ride. As the cylinder (14) moves in an extending direction, the bearing balls (30) move out of the counter bore (32) allowing free extending movement of the cylinder (14). As the cylinder (14) moves in a retracting direction, the bearing balls (30) are driven down into the steep taper (36) preventing the cylinder (14) from retracting.
