Abstract

L'invenzione riguarda una valvola di riciclo dei gas di scarico con un manicotto tubolare di guida di gas di scarico disposto in un canale di aspirazione. E' previsto che al manicotto valvolare (34) sono associati mezzi, che consentono un raffreddamento del manicotto valvolare (34) specialmente in corrispondenza di una superficie di contatto (54) fra il manicotto valvolare (34) e il canale di aspirazione (14) (Figura 2).
