Abstract

Vanne à ressort magnétique de torsion pour ligne d’échappement d’un moteur à combustion interne Cette vanne (30) comprend un corps de vanne (32) tubulaire définissant un passage de circulation des gaz d’échappement (33) et un clapet (34) monté mobile en rotation par rapport au corps de vanne (32) autour d’un axe de rotation (P-P’) entre une position d’obturation et une position de libération du passage de circulation des gaz d’échappement (33). La vanne (30) comprend également un organe (50) de rappel du clapet (34) vers une position de repos, ledit organe de rappel (50) comprenant un ressort magnétique de torsion (51) formé d’un rotor aimanté (52), fixe en rotation relativement au clapet (34) et coaxial à l’axe de rotation (P-P’), et d’un stator aimanté (54), fixe en rotation relativement au corps de vanne (32) et coaxial à l’axe de rotation (P-P’).
