Abstract
A cam shaft phaser, including: an axis of rotation; a rotor arranged to receive torque from an engine and including a plurality of radially outwardly extending protrusions; a stator including a plurality of radially inwardly extending protrusions; and a plurality of chambers. Each chamber is circumferentially bounded by first and second radially outwardly extending protrusions. A respective radially inwardly extending protrusion is located in each chamber.
