Abstract
In a valve control for an internal combustion engine, particularly an exhaust gas recirculation valve comprising a valve with a valve stem and a valve disc axially movably supported in a housing for moving the valve disc out of, and into, seating engagement with a valve seat for opening and closing a gas flow passage, a rotary magnet structure with a motion transmitting mechanism is provided with an actuator arrangement for converting rotation of the rotary magnet to axial motion of the valve member by way of a cam track structure disposed between means rotating with the rotary magnet arrangement and a valve guide supporting the valve for only axial movement from and onto the valve seat.
