Abstract
A camshaft phaser that includes a rotor and a sprocket. A plurality of lobes of the sprocket are spaced to receive a plurality of vanes of the rotor, thereby defining retard and advance pressure chambers when the rotor rotates with respect to the sprocket between retard and advance positions. When the rotor rotates between the retard and advance positions, gap surfaces of the lobes cooperate with gap surfaces of the vanes to form fluid gaps therebetween, wings of the lobes fit into receiving surfaces of the vanes, and stop surfaces of the vanes abut the sides of the lobes.
