Abstract
A camshaft phaser for varying the phase relationship between a crankshaft and a camshaft includes stator having a plurality of lobes. A rotor rotatable about a camshaft axis is disposed coaxially within the stator and has a plurality of vanes interspersed with the lobes to define advance chambers and retard chambers. A lock pin is slidably disposed along a lock pin axis within the rotor for selective engagement with a first lock pin seat and for selective engagement with a second lock pin seat. The lock pin has a lock pin width in a circumferential direction relative to the camshaft axis and a lock pin length perpendicular to the lock pin width and to the lock pin axis such that the lock pin width is less than the lock pin length.
