Abstract

Dispositif de chauffage d'un corps. Il comporte un élément chauffant 6 comprenant une résistance chauffante entourée par une enveloppe 6a en matériau bon conducteur de la chaleur, disposée en contact thermique avec le corps à chauffer 4, et une unité de régulation thermique ; le corps 4 se refroidit plus vite à son extrémité 4a que dans le reste dudit corps; un premier capteur de température 9a est placé au droit de l'extrémité 4a et un deuxième capteur 9b est placé au droit du reste dudit corps 4; des moyens sont prévus pour additionner les signaux fournis par ces capteurs 9a, 9b et pour transmettre le signal somme à l'unité de regulation. L'invention s'applique notamment aux buses de presse à injection.
