摘要
FIELD: turbomachines; proportioning devices.;SUBSTANCE: invention relates to control of flow rate of fluid media, particularly, to methods and devices for metering out fuel and supply of fuel nozzles of combustion chambers of turbomachines. Proposed liquid proportioner 12 has metering valve 14 installed for sliding in bushing 26 under pressure of liquid medium to provide intake of said medium and its delivery to liquid medium users 24. Valve is provided with hole 16 on inlet end getting into longitudinal channel 18 for liquid medium, and valve head 20 on outlet end provided with metering slots 22 for liquid medium opening into longitudinal channel and determining variable passage sections to liquid medium users. Valve head contains additionally at least one mainly cross hole 38 after metering slots in direction of liquid medium flow. Said hole communicates with longitudinal channel and determines at least one constant passage section to indicated liquid medium users.;EFFECT: provision of uniformity of fuel delivery between nozzles at one and the same delivery pressure.;12 cl, 5 dwg
