FIELD: engines and pumps.
SUBSTANCE: invention relates to propulsion engineering, particularly, to atomisers with microprocessor control for fuel injection in ICE cylinder. Proposed atomiser comprises casing with high-pressure feed channel and discharge channel. Booster sleeve accommodates shutoff booster to make hydraulic control chamber, sprayer with seat, needle chamber and spraying hole. Needle interacts with said seat and said shutoff booster via jack. Hydraulic control chamber communicates with high-pressure fuel feed channel via jet. It communicates with discharge channel via control valve with its spring-loaded stem coupled with electromagnet armature. In compliance with this invention, said booster incorporates with shutoff valve while jack is an elastic deformation element owing to its sections of smaller cross-section which allows its deformation in axial direction.
EFFECT: decreased fuel overflow from high-pressure chamber via booster gap, longer life of atomiser.
