Abstract

Carburateur comportant un conduit d'admission muni d'un papillon 2 commandé par le conducteur et un enrichisseur 20 de mélange air/combustible réglant la section d'un passage offert au combustible aspiré par le système de jaillissement principal. L'enrichisseur comporte un élément pneumatique relié en permanence à un point 31 du conduit d'admission 1 situé en aval de l'organe d'étranglement principal et à un point 32 du conduit d'admission qui passe d'amont en aval du papillon, lorsque son ouverture dépasse une valeur déterminée. Application aux moteurs à combustion interne.
