FUEL VALVE FOR INJECTION OF IGNITION LIQUID FUEL AND FOR INJECTION OF GAS-FUEL INTO THE COMBUSTION CAMERA OF THE INTERNAL COMBUSTION ENGINE WITH SELF-IGNITION

摘要

1. A fuel valve (50) for injecting ignition fluid and for injecting gaseous fuel into a combustion chamber of a self-ignition internal combustion engine, comprising: an elongated fuel valve body (52) with a rear end and a front end, an injector (54) with nozzle openings ( 56), located at the front end of the specified housing (52), a passageway (53) for the inlet of gaseous fuel for connection with a source (60) of compressed gaseous fuel, made with the possibility of axial movement of the needle (61) of the valve, and having a closed position and an open position, moreover, in the said closed position, the needle (61) of the valve axially displaceable abuts the seat (69) and thereby prevents leakage of gas fuel inlet (53) to the nozzle (54), av the indicated open position, the axially displaceable needle (61) is lifted from the specified seat (69), thereby ensuring leakage from the passage opening (53) for the intake of gaseous fuel to the nozzle (54), the drive system for control the indicated movement of said axially displaceable needle (61) of the valve between said closed position and said open position, a passage hole (78) for a pilot fluid for connecting to a source of pilot fluid, a channel (67) for injecting a pilot fluid passing in an axial direction inside said axially biased needle (61), characterized by a pump chamber (80) with an inlet connected in fluid communication with said passage (78) for firing a fluid and the output of
