Abstract
A motion limiter system for a cam phaser includes a retractable motion limiter pin that is selectively extendable from a rotor in a cam phaser to contact a lobe on a stator to provide a positive stop for the rotor prior to engagement of a locking pin. Alternatively, the cam phaser may include two pins that are selectively extendable from opposite openings in a hole in the rotor to engage seats that are slightly offset from one another.
