ABSTRACT:
An electromechanical valve assembly46for an internal combustion engine36is provided. The valve assembly46includes a rotor68centered about a first axis122having a bore114extending generally axially therethrough. The valve assembly46further includes a stator66operatively disposed about the rotor68for producing a torque to cause rotation of the rotor68about the axis122. Finally, the valve assembly46includes a valve70having a valve stem126and a valve head84The valve stem126extends generally axially through the bore114of the rotor68. The valve stem126is also configured to move generally axially responsive to the rotation of the rotor68to selectively engage and disengage the valve head84with a valve seat124of the engine36.
