Abstract
A cam phaser wherein the stator is integral with either the back plate or the front cover plate. The integral stator may be formed by any desired forming technique, such as, for example, by machining, casting, welding, or injection molding. Preferably, however, the integral stator is formed in a single molding step by powdered metal forming using powdered aluminum. Cap seals are provided for sealing the hydraulic chambers of the cam phaser.
