1. A dual independent phasing system, comprising:
a drive sprocket arranged to receive torque; a first phaser section including:
a first stator non-rotatably connected to the drive sprocket; and,a first plurality of chambers formed by a first rotor and the first stator; a second phaser section, located in a first axial direction from the first phaser section, and including:
a second stator non-rotatably connected to the drive sprocket; and,a second plurality of chambers formed by a second rotor and the second stator; a first portion of a first camshaft:
non-rotatably connected to the first rotor and extending past the first stator in a second axial direction, opposite the first axial direction; and,including a first plurality of channels arranged to supply fluid to the first plurality of chambers; and, a second portion of the first camshaft:
non-rotatably connected to the first portion of the first camshaft and extending past the second stator in the first axial direction; and,including a second plurality of channels arranged to provide fluid to the second plurality of chambers, wherein: the first plurality of chambers is arranged to circumferentially position, in response to fluid pressure in the first plurality of chambers, the first and second portions of the camshaft with respect to the drive sprocket; and, the second plurality of chambers is arranged to circumferentially position, in response to fluid pressure in the second plurality of chambers, the second rotor with respect to the drive sprocket. |
