GAS TURBINE ENGINE FUEL FEED AND CONTROL SYSTEM

摘要

FIELD: engines and pumps. ^ SUBSTANCE: has turbine engine furl feed and control system effects automatic control over gar turbine engines. The proposed system comprises centrifugal pump driven from the engine and a displacement proportioner with adjustable drive. The said proportioner represents a gear-type hydraulic mechanism with its intake line accommodating a choke valve to maintain preset pressure differential at the proportioner thus stabilising the fuel flowing over inside the proportioner. ^ EFFECT: higher accuracy of fuel metering irrespective of centrifugal pump drive rpm. ^ 1 dwg
