FIELD: engines and pumps.
SUBSTANCE: proposed system comprises fuel consumption proportioner with the lines of fuels proportioned and not proportioned. Constant pressure difference controller (CPDC) consists of a sensitive and actuator elements. Device to distribute fuel among nozzle manifolds is connected/disconnected with preset fuel consumption hysteresis and comprises control valve with spring-loaded control element. Spring chamber of said control element communicates with the line of proportioned fuel, while control chamber communicates with the control pressure line. Fuel flow through aforesaid control valve chambers at pressure differing at said chambers. Rigidity of CPDC actuator spring provides for required hysteresis of control valve connection/disconnection.
EFFECT: ease of manufacture, reduced weight and sizes, simplified design.
