Abstract

L'invention concerne un dispositif de dosage pour carburant (1) pour moteur à combustion interne, en particulier à allumage spontané, à compresseur d'air, dispositif comprenant une première pompe à carburant (5) pour le refoulement d'un premier carburant, tel qu'un carburant diesel, et une seconde pompe à carburant pour l'alimentation d'un second carburant, en particulier d'un carburant gaz de pétrole liquéfié (GPL). Le premier carburant et le second carburant sont prélevés à un réservoir, respectivement (2, 3), et sont envoyés à un récipient de mélange à pression (11); à partir du récipient de mélange à pression (11), un carburant mixte est envoyé, via une pompe haute pression (8), à un système d'injection (15) du moteur à combustion interne, ledit système d'injection (15) présentant une conduite de retour (10) commandée par une soupape de refoulement et de dérivation, conduite via laquelle, dans le système d'injection (15), le carburant mixte en excès est envoyé au récipient de mélange à pression (11). L'invention a pour but d'obtenir un dispositif de dosage de carburant à risques de fonctionnement réduits et, à cet effet, est caractérisée en ce que le récipient de mélange à pression (11) présente une chambre tampon de pression de vapeur (12) qui peut être connectée à une conduite de retour de vapeur qui débouche dans la chambre de pression de vapeur (2.1) du réservoir (2) du second carburant.
