Description

Druckzerstäuber für Brennstoff bei Brennkraftmaschinen Den Gegenstand der vorliegenden Erfindung bildet ein Druckzerstäuber für Brennstoff, welcher in die Brennstoffzuleitung bei Brennkraftmascbinen eingebaut wird. Bei solchen Brennkraftmaschinen, welchen der Brennstoff nicht unter Unterdruck#virkung des Zylinderventils zugeführt wird, sondern bei welchen der Brennstoff unter Druck zugeführt wird, ist es notwendig, damit kein Brennstoffverlust eintritt, das Ende der Brennstoffzuleitung mit einem kleinen Ventil zu verschließen. Dieses Ventil öffnet sich nun gleichzeitig mit der Druckförderung des Brennstoffes von der Förderpumpe her und gleichzeitig mit Beginn der Saugperiode im Zylinderkopf. Infolge dieser gleichzeitigen Zusammenwirkung der Druckperiode in der Brennstoffzuführungsleitung und der Saugperiode des Zylinderventils würde der ausgeschlcu.derte Brennstoff ohne die erforderliche Zerstäubung und Luftzumischung in den Zylinderkopf eintreten. Um dieses zu verhindern, wird eine besondere gelochte Kappe auf dem Ende der Brennstoffdruckleitung angeordnet und dadurch die erforderliche Zerstäubung und Luftzumnschung erzielt.Pressure atomizer for fuel in internal combustion engines The object of the present invention forms a pressure atomizer for fuel, which in the fuel supply line is installed in internal combustion engines. In such internal combustion engines, which the fuel is not supplied under the negative pressure effect of the cylinder valve but where the fuel is supplied under pressure, it is necessary to so that no fuel loss occurs, the end of the fuel supply line with a to close the small valve. This valve now opens at the same time as the Pressure delivery of the fuel from the delivery pump and at the same time as the start the suction period in the cylinder head. As a result of this simultaneous interaction of the Pressure period in the fuel supply line and the suction period of the cylinder valve would be the excluded fuel without the necessary atomization and air admixture enter the cylinder head. To prevent this, a special hole is made Cap placed on the end of the fuel pressure line and thereby the required Atomization and air supply achieved.

Auf der beiliegenden Zeichnung ist die Anordnung in Fig. i in senkrechtem Schnitt dargestellt und in Fig. 2 im horizontalen Schnitt durch die Kappe.On the accompanying drawing, the arrangement in Fig. I is in the vertical Section shown and in Fig. 2 in a horizontal section through the cap.

Der Brennstoff wird durch die Leitung 8 in einen Vorraum g hineingedrückt. Das Ende der Brennstoffleitung 8 ist durch ein Ventil 17 geschlossen, das unter leichtem Federdruck steht. Dieses Ventil 17 schließt die Brennstoffleitung 8, sobald die Druckförderung nachläßt oder aufhört. Das Einlaßventil für den Zylinderkopf ist mit 1q. bezeichnet und führt zu dem Brennstoffkanal 15. Oberhalb der Mündung des Rohres 8 und oberhalb des Ventils 17 ist nun eine Kappe i9 angeordnet, welche unten bei 2o offen ist und oben ebenfalls abgeschlossen ist, bis auf eine Anzahl von Bohrungen 21, welche am Umfange der Kappe angeordnet sind. Durch diesen Deckel der Kappe i9 wird der ausgespritzte Brennstoff gezwungen, in zahlreichen Stromlinien durch die Bohrungen 21 zu treten und sich innerhalb der Kappe mit der Luft, dne durch 2o eingetreten ist, zu vermischen, noch mehr aber nach Durchtritt durch die Kappe mit der Außenluft. Alsdann erst wird dieses Brennstoffluftgemisch durch das Ventil 1q. in den Kanal 15 weiterbefördert.The fuel is pressed through the line 8 into an anteroom g. The end of the fuel line 8 is closed by a valve 17, which is below light spring pressure. This valve 17 closes the fuel line 8 as soon as the pressure delivery decreases or stops. The inlet valve for the cylinder head is with 1q. denotes and leads to the fuel channel 15. Above the mouth of the tube 8 and above the valve 17 is now a cap i9 which is open at the bottom at 2o and is also closed at the top, except for a number of bores 21, which are arranged on the circumference of the cap. Through this lid The cap i9 forces the ejected fuel into numerous streamlines to enter through the holes 21 and inside the cap with the air, dne has occurred through 2o, to mix, but even more after passing through the Cap with the outside air. Only then is this fuel-air mixture through the Valve 1q. conveyed on in the channel 15.
