FIELD: engines and pumps.
SUBSTANCE: proposed atomiser comprises control valve 18. Said valve controls fuel flow via drain channel 14 made in atomiser part 6. Fuel flows from control chamber 5 confined by axially displacing valve element 2 toward zone 12 of atomiser 1 at low pressure of said zone. Valve 18 comprises atomiser part 6 including valve bush 17. The latter is arranged to displace directly inside guide element 26. Said element represents a separate element secured to atomiser part 6 with interference fit on taper section. Said guide element 26 is provided with transverse hole 31, 32 for heat removal from drain channel 14.
EFFECT: simplified design.
