Abstract

Dispositif casse-vide pour carburateur de moteur à combustion interne. Il comprend deux ensembles 38 et 40 à diaphragme et un équipage mobile 18 à plongeurs, commandé par les ensembles à diaphragme, de manière que le déplacement de cet équipage puisse s'effectuer en deux phases pouvant être retardées par des valves de dosage. Ces phases de mouvement dépendent de sources séparées de vide. Lune de ces sources peut être mise en communication avec le dispositif sous la commande d'une valve sensible à la température. Domaine d'application : carburateurs de moteurs à combustion interne.
