MOTOR VEHICLE INTERNAL COMBUSTION MOTOR EXHAUST GAS RECIRCULATION VALVE HAVING A MECHANICALLY COMMUTATED DRIVE MOTOR

摘要

The invention relates to an electrical motor vehicle internal combustion motor exhaust gas recirculation valve (10) having a mechanically commutated drive motor (12) and a step-down gear mechanism (14) which is mechanically connected to a valve body (18). The drive motor (12) has at one longitudinal end a plastic carrier panel (26) which lies in a transverse plane and has on its proximal side at least two commutator brushes (40, 41) and interference suppression reactor coils (44, 45) which are assigned to the brushes (40, 41) and on its distal side at least one interference suppression capacitor (50, 51, 52). The interference suppression capacitor (50, 51, 52) is so well thermally insulated with respect to the motor rotor that the capacitor is not heated above 150°.
