Abstract: A camshaft phaser is provided for varying the phase relationship between a crankshaft and a camshaft in an engine. The camshaft phaser includes a stator having lobes. A rotor disposed within the stator and rotatable between a full retard position to a full retard position includes vanes interspersed with the stator lobes to define alternating advance and retard chambers. A lock pin selectively engages a lock pin seat for preventing a change in phase relationship between the rotor and the stator at a predetermined aligned position between the full advance and full retard positions. A counterbalancing member is located within one of the advance chambers or the retard chambers, attached to a vane to thereby apply a torque between the rotor and the stator only when the rotor is between the predetermined aligned position and one of the full retard position and the full advance position.
