FIELD: engines and pumps. ^ SUBSTANCE: invention may be used in gas turbine engine control systems. Additionally used is restricting slide valve (SV) with its spring chamber communicated with GMR outlet while sensitive chamber is communicated with fuel line between GT and RC and, via working edge (SV) and throttle resistance (TR) and selector, it is communicated with fuel pump outlet fuel line. Note here that spring tightening force is defined experimentally proceeding from fuel pressure upstream of RC that corresponds to minimum stable operation of gas turbine engine (idle operation), while flow characteristic of TR is selected during acceptance tests to ensure fuel flow rate via RC corresponding to maximum admissible value for said engine. ^ EFFECT: ruling out possibility of uncontrolled variation of fuel flow rate in combustion chamber, higher reliability and safety. ^ 1 dwg |
