Improvements to turbomachine injectors

摘要

The fuel injector (2) consists of a housing (4) with a pressurised fuel inlet (6) and first and second valves (10, 36), the first letting fuel into the housing, and the second delivering the fuel to the consumer units (48). The injector incorporates a diaphragm (66) between the inlet (6) and the first valve to fix the incoming fuel flow at a predetermined level, and a regulator (68) to define a third threshold pressure while acting as a stop for the second valve.
