Abstract

a. L'invention concerne une installation pour régler le rapport des débits air/carburant du mélange alimentant un moteur à combustion interne. b. Cette installation est caractérisée en ce qu'un rétrécissement de diamètre est prévu dans la tubulure d'aspiration d'air ainsi que dans le conduit d'amenée de carburant, les pressions différentielles ainsi produites étant comparées par une soupape à pression différentielle dont l'organe de réglage agit sur une pression de commande. c. L'invention est applicable à l'alimentation des moteurs à combustion interne.
