Beschreibung
Zusammenfassung:	FIELD: mechanical engineering; gas turbine engines. SUBSTANCE: proposed device has shutoff valve position control unit made in form of switching on and off electromagnets arranged in housing and mechanically coupled with normally closed valves which hydraulically connect command space of shutoff valve with drain and inlet main lines, respectively, two control valves mechanically interacting with shutoff valve piston and connecting command space through channels with fitted-in jets with drain main line in ON position and with inlet main line in OFF position of shutoff valve. EFFECT: simplified design of device for automatic control of fuel delivery into combustion chamber of gas turbine engine owing to dispensing with complex control devices, improved reliability of fuel delivery control, prevention of working medium draining with shutoff valve in operating positions. 2 cl, 1 dwg
