1. A variable camshaft phaser, comprising:
a stator arranged to receive torque from an engine; a rotor arranged to be non-rotatably connected to a camshaft; a first wedge plate and a second wedge plate radially disposed between said stator and said rotor; a spinner, operatively arranged about a central hub, said spinner having a twisting groove therein; a paddle arranged about said spinner comprising an annular ring having an engagement member extending outwardly therefrom, said engagement member having a proximate section and a distal section; said proximate section operatively arranged to engage said twisting groove, and said distal section operatively arranged to engage either said first or second wedge plates; wherein said spinner, paddle, central hub, and engagement member are operatively arranged to displace said first or said second wedge plate in either an advance mode or in a retard mode; wherein, in said advance mode, the central hub and the spinner are displaced in a first axial direction to enable rotation of the paddle with respect to the rotor, and engage said first wedge plate in a first circumferential direction; and, wherein, in said retard mode, said central hub and said spinner are displaced in a second axial direction, opposite said first axial direction, to enable rotation of said paddle with respect to said rotor, and engage said second wedge plate in a second circumferential direction, opposite said first circumferential direction. |
