ABSTRACT:
A camshaft has a front part forming a journal part for a wheel of a timing pulley (a drive member). A stub shaft (a driven member) is secured to the front of the camshaft and disposed within a cylindrical body of the timing pulley. An annular slide is disposed and coacts with the cylindrical body and the stub shaft for phasing action. The magnitude of axial movement of the slide determines the magnitude of relative rotation between the timing pulley and stub shaft. Fixedly attached to a timing pulley cover is a body formed with a cylindrical bore receiving a piston and a valve bore receiving a spool of a valve for regulating supply of fluid to and discharge thereof from a pressure chamber defined by the piston in the cylindrical bore. A motor is fixedly attached to the timing pulley cover is coupled with a worm of a worm gearing including a worm gear. A motion connection between the piston and the slide is established by a piston rod, a push rod, a cross bar and a slide spring biasing the slide. A lever has one end abutting on an actuator pin for a spool of the valve and the opposite end pivoted to the worm gear. The lever is operatively coupled with the piston rod. The lever provides a position feedback of the piston rod to the valve.
