FIELD: engines and pumps.
SUBSTANCE: ICE fuel injector represents an impact fuel nozzle. It comprises case whereto screwed be nut is the casing of sprayer with conical seat. Sprayer case houses axially displacing valve stem with one end extends outside said case so that it makes a valve assembly with conical seat. On electrically-controlled injector one side accommodates electromagnet its body being provided with winding with core arranged therein and locked by nut. Additionally, sprayer case accommodates spring-loaded valve stem aligned with valve stem and rigidly coupled therewith. Atomiser case houses hammer axially displacing therein. Said hammer is pressed by spring against electromagnet core so that clearance is formed between hammer opposite end and valve stem.
EFFECT: higher quality of fuel sprayer, simplified design and electromagnetic drive.
