Abstract: A valve device for an internal combustion engine. The valve device includes an actuator which moves a valve rod, a housing with an inlet and an outlet, a valve closing member attached to the valve rod which is lowered onto and lifted off of a first valve seat, a non-return plate which is loaded via a spring force in a direction of a second valve seat, and a sealing lip which is formed on the second valve seat or on the non-return plate. The sealing lip extends from the second valve seat in a direction of the non-return plate or from the non-return plate in a direction of the second valve seat. The sealing lip is formed with a free end which is inclined in a direction of a side on which a higher pressure is applied when the non-return plate rests on the second valve seat.

Abstract: An actuator for a valve in an internal combustion engine includes an actuator housing, an electromagnet arranged in the actuator housing, the electromagnet comprising a yoke plate arranged at an axial end of the actuator housing, at least one clamping plate, and a sealing ring arranged at an axial side of the yoke plate facing the electromagnet. The sealing ring is pressed axially towards the yoke plate via the at least one clamping plate.
