Abstract (en)

[origin: EP0689006A1] The procedure consists of circulating part of the total fuel need to the two injectors through the take-off injector regardless of the operating mode, and removing the surplus fuel for transmission to the cruising speed injector. The take-off injector has fuel outlet orifices (8) and a first duct (11) designed to direct part of the total fuel feed to a chamber (6) inside the injector, returning it through a central channel (12) when the injector is not in operation. The orifices are closed by a spring-loaded valve (16) with apertures (19) connecting the channel and chamber. <IMAGE>
