A fuel supply installation for a turbojet including two volumetric pumps for combining their flow rates is disclosed. The pumps include a main pump dimensioned for the full gas rate and an auxiliary pump controlled and dimensioned to provide the supplementary flow rate necessary on ignition.

Fuel supply installation of an aircraft turbojet

This injector with two valves () which open at different fuel pressures so as to establish a primary flow regime and then a secondary flow regime is characterized in that the primary regime is enriched with fuel via an orifice () which adds a branch to the primary flow path of the fuel, but which is closed when the secondary valve is displaced so as to prevent enrichment of the fuel in the secondary regime. This invention applies in particular to certain aircraft engines.

Two-stage fuel injector

A fluid metering device including a metering valve capable of sliding in a bushing under fluid feed pressure in order to enable a fluid to be admitted and then ejected. The valve can have, at a first end, an opening opening out into a longitudinal fluid admission bore, and at a second end forming an end wall, a valve head provided with fluid metering slots opening out into the longitudinal bore and defining varying flow sections. The valve head can further include at least one substantially transverse orifice disposed downstream from the metering slots in the fluid flow direction, the orifice communicating with the longitudinal bore and defining at least one fixed flow section.

Fuel metering device for a turbomachine injector

A system for injecting fuel into a turbomachine comprising N fuel injectors placed in a combustion chamber of the turbomachine and fed from a fuel tank, the injection system further comprising, interposed between the N injectors and the tank, a single pumping means for taking fuel from the tank and delivering N metered flow rates of fuel to the injectors.
