A fuel-injection device in a turbomachine

A fuel-injection device in a turbomachine, comprising a high-pressure pump ( 10 ) supplying a flow control valve ( 16 ), whose outlet is connected via a pressurization and cut-off valve ( 20 ) to a fuel-injector ( 18 ) feed pipe ( 22 ), the valve ( 20 ) being connected to the inlet and to the outlet...

Beschreibung
Zusammenfassung:	A fuel-injection device in a turbomachine, comprising a high-pressure pump ( 10 ) supplying a flow control valve ( 16 ), whose outlet is connected via a pressurization and cut-off valve ( 20 ) to a fuel-injector ( 18 ) feed pipe ( 22 ), the valve ( 20 ) being connected to the inlet and to the outlet of the pump ( 10 ) in order to define two fuel pressurization thresholds, one being used to start-up and restart the turbomachine, and the other being used for operating the turbomachine as from an idle speed and for commanding an equipment with variable geometry ( 24 ).
