Abstract

L'invention concerne un appareil de pompage de combustible comprenant une pompe d'injection ayant un piston 19 qui peut être soumis à une pression de fluide variable pour déterminer le moment de l'injection. Le piston est rappelé par un organe élastique 19a et un organe 25 sert de butée pour le piston. L'organe 25 est relié à un dispositif sensible à la température grâce à quoi, lorsque le moteur est froid, la butée détermine la position du piston de façon à obtenir une avance déterminée lors du démarrage du moteur. La butée se déplace lorsque le moteur est chaud de manière à permettre au piston de modifier l'avance sur toute la plage de reglage.
