CA 2431286

The invention relates to a method and a device (1) for supplying fuel to a combustion chamber which comprises at least one main injector (3) and at least one pilot injector (2). The device comprises a fuel tank (4), a line system (5) coupled from the fuel tank to the injectors (2, 3), a pump (6) for pumping fuel from the tank to the injectors, and a first regulator valve (7) for regulating the flow of fuel in a first line (8) in the system whichis connected to said pilot injector (2). The device further comprises a second regulator valve (9) for regulating the flow of fuel through a second line (10) in the system, which is connected to said pilot injector (2). The second regulator valve (9) is designed to regulate a substantially smaller flow than the first regulator valve (7).

L'invention concerne un procédé et un dispositif (1) permettant de céder du carburant à une chambre de combustion et comprenant au moins un injecteur principal (3) et au moins un élément de préinjection (2). Ce dispositif comporte un réservoir de carburant (4), un système de conduites (5) reliant le réservoir aux injecteurs (2, 3), une pompe (6) destinée à pomper le carburant dans le réservoir pour le céder aux injecteurs, et une première soupape de régulation (7) destinée à réguler le flux de carburant dans une première conduite (8) du système, laquelle est reliée à l'élément de préinjection (2). Le dispositif comprend également une deuxième soupape de régulation (9) destinée à réguler le flux de carburant dans une deuxième conduite (10) du système, laquelle est reliée à l'élément de préinjection (2). La deuxième soupape de régulation (9) est conçue pour réguler un flux sensiblement plus petit que la première soupape de régulation (7).
