Beschreibung
Zusammenfassung:	FIELD: engines and pumps. ^ SUBSTANCE: pump-jet comprises housing, control and pressure chambers coaxially arranged there inside and accommodating pressure booster with piston and plunger, fuel feed line with fill valve communicating with accumulator hydraulic line, line to discharge fuel from the said control chamber, control solenoid valve, sprayer with needle furnished with super-needle space communicating with the pressure chamber. The proposed jet pump comprises hydraulic locking booster mounted aligned with the sprayer with needle, booster super-piston chamber communicating directly, via fuel channel, with the accumulator hydraulic line. The said booster sub-piston chamber, that is, the super-needle space, communicates with additional discharge channel connected with the discharge chamber downstream of the solenoid valve. ^ EFFECT: higher fuel injection properties and pump-jet reliability. ^ 8 cl, 2 dwg
