FIELD: mechanical engineering; internal combustion engines.
SUBSTANCE: invention relates to devices for injecting fuel under high and superhigh pressure into internal combustion engine. Proposed device for injecting fuel under high pressure through atomizer contains housing with high-pressure delivery line and no-pressure drain line. Housing is connected with common high-pressure accumulator and electromagnetic valve to control operation of atomizer. Movable bushing is inserted into housing. Valve engages with one end face of bushing. Other end face of bushing limits control chamber in which branch from hole of high-pressure delivery line terminates.
EFFECT: improved efficiency of injection, prevention of secondary injection, simplified design.
