DEVICE TO FEED FUEL TO THERMAL ENGINE NOZZLE

摘要

FIELD: engines and pumps.SUBSTANCE: device to feed fuel to nozzle (1) comprises pressure booster with case (2) accommodating spring-loaded stepped piston-booster (3). Barrel-like case (2) houses disc (11) opposed to booster piston (3). Electromagnetically controlled drain valve (12) is arranged behind said disc. Said valve as-opened communicates chamber (14) with drain pipe via holes in disc (11) and in case (2). Booster piston houses return piston (15). Chamber between disc (11) and booster piston (3) communicates with fuel accumulator (18) arranged in cylinder head (5).EFFECT: decreased fuel pressure losses, increased fuel injection pressure.2 cl, 2 dwg
