STEPPED ROTOR FOR CAMSHAFT PHASER

摘要

A rotor for a camshaft phaser assembly for an internal combustion engine. The rotor includes a base portion from which protrudes a plurality of vanes spaced over the circumference of the base portion of the rotor. An increased diameter stepped portion of the base portion of the rotor is provided over at least one section between at least two of the protruding vanes. The increased diameter portion allows for insertion of at least one locking pin assembly within the base portion of the rotor, reducing the remaining rotor base portion diameter to at least reduce material weight and size of the camshaft phaser assembly.
