Abstract: A variable camshaft timing phaser having a locking pin directly influenced by engine oil, which is not impacted by any intervening valves. The locking pin is comprised of a tapered pin, which fits into a tapered recess. The locking pin is biased towards engaging by a spring, and is retracted by oil from the engine oil supply. The locking pin remains disengaged from the tapered recess as long as the oil pump is on.

Abstract: A locking device is provided to lock the phaser vane and sprocket together at all times except when the phaser is moving from position to position. The locking device ensures that the phaser is locked for start conditions and ensures the prevention of noise from being generated. The locking device also ensures that the timing accuracy of the phaser is controlled at a number of positions for the steady state condition.

Abstract: A phaser for an internal combustion engine having at least one camshaft. The phaser has a housing and a rotor. The housing has an outer circumference for accepting a drive force and the rotor connects to a camshaft coaxially located within the housing. The housing and the rotor define at least one vane separating chambers, advance and retard. The vane shifts the relative angular position of the housing and the rotor. The phaser also includes a spool valve comprising a spool slidably mounted within in a bore in the rotor. The spool routes operating fluid from a supply of pressurized fluid to the chambers. At least one passage from the supply to the chambers provides makeup fluid. The passage includes a check valve and a restrictor.

Abstract: A variable camshaft phase adjustment device (phaser) for an internal combustion engine having at least one camshaft. The phaser has a housing having an outer circumference for accepting a drive force, and a rotor connected to a camshaft coaxially located within the housing. The housing and the rotor are capable of rotation to shift the relative angular position of the camshaft and the crankshaft. The spool valve comprising a spool slidably mounted within a bore in the rotor. In the spool a chamber is present that has an input communicating with the bore the spool is mounted in, an output communicating with the outside, and an air flow restriction. Hydraulic fluid from the input communicating with the bore is prevented from communicating with the outside by the air flow restriction. The air flow restriction is either in the input communicating with the bore or the output communicating with the outside.
