FUEL CONTROL

Fuel flow to the burner (10) of a gas turbine engine (15) is turned on and off by a minimum pressure valve (60) controlled by a fluid pressure operated sequence valve (110). The sequence valve includes a valve element (125) set by the pressurization thereof with fuel discharged from a pump (35). The...

Beschreibung
Zusammenfassung:	Fuel flow to the burner (10) of a gas turbine engine (15) is turned on and off by a minimum pressure valve (60) controlled by a fluid pressure operated sequence valve (110). The sequence valve includes a valve element (125) set by the pressurization thereof with fuel discharged from a pump (35). The setting of the sequence valve element (125) is maintained by a fluid latch also energized by fuel discharged from the pump whereby no complex linkages or electric motors are required for the setting of the sequence valve and the maintenance of such setting.
