SYSTEM FOR TILLFORSEL AV GASFORMIGT BRENSLE

摘要

In a gaseous fuel delivery system for delivering gaseous fuel to the combustor of a gas turbine engine wherein the delivery system includes a fuel injector having a nozzle orifice, a gaseous fuel supply passage providing fluid communication between the nozzle orifice and a source of gaseous fuel under pressure, an improvement is presented comprising means for preventing pressure perturbations occurring within said combustor from compressing gaseous fuel in at least a portion of the fuel delivery system.
