Vorrichtung zur Verteilung von Brennstoff über mehrere Einspritzdüse

摘要

The present invention relates to a device (1) for distributing (splitting) fuel between the injectors (2) of a turbomachine. Distributors (splitters) (9) with two outlets (19a, 19b) are interposed between the injector lines (7). They are fed in parallel by the fuel supply pipe (3). Each distributor (9) feeds the two adjacent injectors (2a, 2b) and each injector (2) receives a fuel flow from the two adjacent distributors. Each distributor (9) includes two pistons (17a, 17b) with identical cross-sections and connected by a tension spring (18). The mass (Ma, Mb) of each piston (17a, 17b) is proportional to the barometric head h of fuel contained in the circuit (21a, 21b) which it supplies. The system is insensitive to load factors (g) and supplies the injectors (2) uniformly.
