Abstract

A valve for controlling the amount of exhaust gas recycled in an internal combustion engine exhaust gas recirculation system is disclosed. The valve comprises a sealing member (2; 14; 32) arranged in a duct (3; 10, 11; 35, 38) for substantially sealingly engaging, in the closed position, an abutment member (5; 13; 33), and rotary actuating means for moving said sealing member from the closed position to an open position. Said rotary actuating means comprise a stator and a rotor of which one is provided with at least one magnet while the other is provided with at least one control winding, said stator and said rotor being mounted in such a way that when no current is flowing through the control winding, the sealing member is urged against the abutment member by residual magnetic forces.
