摘要： 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).
