Abstract (en)
[origin: WO0223032A1] The invention relates to an exhaust gas recirculation valve (1) for a combustion engine comprising an actuating device (7) with a control unit formed by a valve shaft (8). An electric-motor driven screw drive mechanism (9) is connected to the control unit (8) for positioning the control unit over a long path with a reduced adjusting force, in addition to an electrical lift actuator (10) with a small adjustment path and a large adjusting force. Said actuators (9, 10) can be dimensioned according to the different operational requirements. According to the force required in the valve adjustment path, the lift actuator can be used with a high adjusting force and a short path for high opening forces and the screw drive mechanism (9) can be used for an exact positioning movement over a long lift path (10).
