Beschreibung
Zusammenfassung:	FIELD: mechanical engineering; fuel devices of internal combustion engines. SUBSTANCE: nozzle has body with hydraulically locking chamber supplied with fuel from feed channel communicating with under-needle space. Hydraulically locking chamber has drain channel with built-in electromagnetically controlled valve. Main throttle is installed in feed channel. Throttling unit and additional channel with auxiliary throttle are made in drain channel between hydraulically locking chamber and valve. Control element of throttling unit is rigidly coupled with needle, is made between valve in drain channel and hydraulically locking chamber and is furnished with piston. This piston limits hydraulically locking chamber being mated with needle. Effective passage area of auxiliary throttle mu2f2 is within 0,083(mu1f1+mu2f2)
