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.
