    Abstract: A vane phaser with an unlocking and relocking mechanism attached to the lock pin, which through the use of a solenoid, distinct from the solenoid used for the oil control valve, which can lock and unlock the vane phaser. When the solenoid is energized and during rotation of the camshaft, the solenoid makes contact with a lever or gear wheel attached to the lock pin, causing the lock pin to rotate. A helical feature on the lock pin itself or on the lever causes the lock pin to move axially, unlocking the vane phaser.

    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 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.

    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 variable cam timing phaser (10) can a drive stator (14) and at least one driven rotor (20, 20a, 20b) mounted for rotation about a common axis. At least one vane-type hydraulic coupling can define at least one expandable fluid chamber (40, 50, 40a, 50a, 40b, 50b) for coupling the at least one driven rotor (20, 20a, 20b) for rotation with the drive stator (14) to enable the phase of the at least one driven rotor (20, 20a, 20b) to be adjusted independently of one another and independently relative to the drive stator (14). A control valve (60) can have at least one inlet port (62), at least one outlet port (64, 64a), and at least one common shared fluid passage (16, 16a, 16b, 16c, 16d). At least one rotatable fluid flow diverter (80, 80a) can be in fluid communication with the at least one common shared fluid passage (16, 16a, 16b, 16c, 16d) for selectively communicating the at least one common shared fluid passage (16, 16a, 16b, 16c, 16d) with the at least one expandable fluid chamber (40, 50, 40a, 50a, 40b, 50b).

    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) coaxial 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.
