FIELD: engines.
SUBSTANCE: invention can be used in fuel feed systems of internal combustion engines (ICE) with self-ignition. Disclosed is fuel valve (50) for injection of ignition liquid fuel and gaseous fuel in ICE combustion chamber comprising elongated body (52), nozzle (54) with holes (56) and through orifice (53) for supply of gaseous fuel and needle (61) valve, made with possibility of axial movement between open and closed positions. Fuel valve includes drive system for controlling movement of needle (61), passage opening (78) for supply of liquid fuel, channel (67) for injection of liquid fuel passing in axial direction inside needle (61), and pump chamber (80), communicated with hole (78) via liquid medium and with channel (67).
EFFECT: pump chamber (80) is compressed when needle (61) is moved from closed position to open, and pump chamber (80) is extended when needle (61) is moved from open position to closed, wherein liquid fuel is supplied to nozzle (54) at compression of pump chamber (80).
