ELECTROHYDRAULIC CONTROLLED NOZZLE FOR FUEL FEED ACCUMULATOR SYSTEMS

摘要

FIELD: mechanical engineering; diesel engines. SUBSTANCE: proposed device is made in form of spray tip mated with housing and provided with fuel feed channels one of which is connected with spray tip space, and the other is connected through jet with space accommodating a plunger. Plunger is provided with channel and it presses needle to spray tip seat together with spring. Electric magnet with armature controls fuel pressure in above-plunger space. Plunger-armature conjugation is precise. EFFECT: increased needle lowering speed. 1 dwg
