Abstract

An air control valve for internal combustion engines having a turbocharger, is placed inside a bypass channel between a pressure side and an intake side of a boost pressure pump of the turbocharger, and has a housing which incorporates an electromagnetic drive unit and a valve unit movable in the housing. The valve unit has a valve rod and a valve closing body attached thereto and a circular sealing element. An arrangement is provided to keep the moving valve unit in a closed position when no current is supplied to the valve unit. At least one pressure compensation opening is provided in the moving valve unit, and the valve closing body has a cylindrical lateral surface which is arranged in such a manner that a housing interior is sealed towards the pressure side or the intake side.
