FIELD: engines and pumps.
SUBSTANCE: proposed ACS comprises fuel flow rate proportioner with constant pressure difference controller connected to main lines of proportioned and not proportioned fuel. Distributor of fuel among manifold of nozzles consists of sensitive element and second manifold connection valve. Main line that feeds fuel to permanently connected first manifold incorporates spring-loaded bypass valve with its outlet connected with main line ahead of second manifold nozzles. Note here that bypass valve opening pressure exceeds that of second manifold opening valve by 0.5…1.5 kgf/cm2.
EFFECT: bypass valve rules out pressure surges in line between tank to combustion chamber by draining excess fuel into second manifold.
