Abstract
Liquid fuel injection nozzle, comprising a bore defined in a body, one end of which forms an exit orifice of reduced size in comparison with the bore, a seat defined within the bore near its said end, a slidable valve member inside the borehole and having an end configured for its cooperation with the seat, fuel input means for pressurizing it into the bore adjacent to said seat, said valve member defining an area subject to the pressurized fuel, so that when such pressurized fuel is supplied through said inlet means, the valvular member moves away from the seat, allowing the flow of fuel through said hole, the nozzle including elastic means intended to urge the valvular member toward the seat, moving such elastic means to this member until its contact with said seat when the flow of combu stiffener through the inlet means is terminated and a step communicating with a variable volume chamber, one of whose walls is defined by the valvular member, so that the volume of such chamber is reduced as the valvular limb is moved away from the valve. Seat, and vice versa, said step also communicating a portion of the drill hole downstream of the seat and from which the said outlet hole extends.
