Abstract
A camshaft phaser, including: a stator; a rotor including a first channel and a second channel and connectable to a camshaft a first wedge plate and a second wedge plate; and a displacement assembly including a first pin in the first channel and a second pin in the second channel. For an advance mode: fluid displaces the first pin to displace the first wedge plate to enable rotation of the rotor, with respect to the stator, in a first direction; and the second wedge plate blocks rotation of the rotor, with respect to the stator, in a second direction. For a retard mode: fluid displaces the second pin to displace the second wedge plate to enable rotation of the rotor, with respect to the stator, in a second direction; and the first wedge plate blocks rotation of the rotor, with respect to the stator, in the first direction.
