   Wenn der Brennstoff von einer normalen   Brennstoffpumpe   mit zwangsläufiger Kolben-   ..   legung gefördert wird, so ist in der Druckleitung ein von der Pumpe getrennter   federbelastejbet   Hilskolben nach Fig. 2 anzuordnen. Dieser besteht aus dem Kolben v und wird durch Spiralfeder w auf das   Kolbengehäuse : t   niedergedrückt. Während des Druckhubes der Pumpe bewegt sich der Kolben v auswärts und springt unter dem Einflüsse der Feder   f   beim Öffnen des Einblaseventiles in seine ursprüngliche Stellung zurück. Die Spannung der Spiralfeder kann durch die Schrauben y geregelt werden. 



   PATENTANSPRÜCHE : 
1. Einrichtung zum Einführen des Brennstoffes in   Verbrennungsklaftmaschinen,   bei denen der Brennstoff mit Hilfe einer Pumpe in einen von Druckluft   durchstlömten Dtuckluftkanal ein-   geführt wird, dadurch gekennzeichnet, dass   das Einblasciuftventil das Druckventil   der Brennstoffpumpe bzw. eines Brennstoffdruckraumes ist.

   If the fuel is conveyed by a normal fuel pump with an inevitable piston arrangement, a spring-loaded auxiliary piston as shown in FIG. 2, separated from the pump, must be arranged in the pressure line. This consists of the piston v and is pressed down on the piston housing: t by the spiral spring w. During the pressure stroke of the pump, the piston v moves outwards and, under the influence of the spring f, springs back into its original position when the injection valve is opened. The tension of the spiral spring can be regulated by the screws y.



   PATENT CLAIMS:
1. Device for introducing the fuel into internal combustion machines, in which the fuel is introduced with the aid of a pump into a compressed air duct through which compressed air flows, characterized in that the Einblasciuftventil is the pressure valve of the fuel pump or a fuel pressure chamber.

Claims

2. Device according to claim 1, characterized by such an arrangement of the pressure valve of the pump, which is expediently designed as a needle, that its tip forms an impact surface for the fuel pressed against the tip and atomizes it.

3. Device according to claim 1 or 2, characterized in that a fuel nozzle or a fuel atomizer is provided in the axis of the Einblaseluftventiles, for the The tip of the injection air valve forms an impact surface which atomizes the fuel emerging from the nozzle under pressure and enables an intimate mixture with the injection air.

4. Device according to claim 1, 2 or 3, characterized in that the spray jet is passed on at right angles to the atomizer axis (s) in order to also promote the atomization by the change in direction.

5. Device according to claim 1, 2, 3 or 4, characterized by a fuel pump with a controlled pressure valve and a pump piston designed as an accumulator piston, the pressure valve being the injection valve.

6. Device according to claim 1, 2, 3, 4 or 5, characterized in that the injection air valve is formed as a controlled pressure valve which opens elastically under the fuel pressure.
