Description

Einspritzdüse für Verbrennungskraftmaschinen, insbesondere mit luftloser Einspritzung Die Erfindung betrifft eine weitere Ausbildung der Einspritzvorrichtung nach Patent 483 126, und zwar wird erfindungsgemäß die Kraft zum Schließen der Düsennadel in der Nähe des Sitzes übertragen, indem die Düsennadel hohl ausgebildet ist und ein stabförmiges Zwischenstück mit beiderseitiger Spitzenlagerung aufnimmt. Dadurch wird erreicht, daß die Schließkraft das Einstellen der Nadel zum Sitz im Düsenplättchen nicht störend beeinflussen kann.Injection nozzle for internal combustion engines, especially with airless ones Injection The invention relates to a further embodiment of the injection device according to patent 483 126, namely according to the invention the force to close the nozzle needle transmitted in the vicinity of the seat by the nozzle needle is hollow and accommodates a rod-shaped intermediate piece with two-sided tip bearings. Through this it is achieved that the closing force adjusts the needle to the seat in the nozzle plate can not interfere.

Auf beiliegender Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt. Die m einer Hülse 2 angeordnete Düsennadel ist mit einer sich bis an die Nähe des Sitzes erstreckenden Bohrung ausgeführt, in welche ein Stab 5 i zur Übertragung des Drukkes der Feder io auf die Nadel mit beiderseitiger Spitzenlagerung eingelegt ist. Auf diese Weise wird der störende Einfluß der Federkraft beim seitlichen Verstellen der Nadel vermieden.On the accompanying drawing are two embodiments of the invention shown. The nozzle needle arranged in a sleeve 2 is connected to an up to carried out the vicinity of the seat extending hole in which a rod 5 i for Transfer of the pressure of the spring io to the needle with the tips on both sides is inserted. In this way, the disturbing influence of the spring force on the side Adjustment of the needle avoided.

Bei der Ausführungsform nach Abb. i ist die Schulter 3 der Hülse-- mit Gleitsitz zwischen dem Düsenplättchen 12 und einem Zwischenstück 52 eingepaßt und wird durch den Flüssigkeitsdruck dichtend gegen das Zw7.- schenstück 52 gehalten. Eine überwurfmutter 6 hält das Zwischenstück 52 fest gegen das Ende 14 des Gehäuses 5. Der Brennstoff wird durch eine Bohrung 7 zugeführt, welche mit einem ringförmigen Kanal 8 am Ende des Gehäuses 5 in Verbindung steht. Etwaige Brennstoffleckmenge wird durch eine Leitung g, abgeführt.In the embodiment according to Fig. I, the shoulder 3 of the sleeve is fitted with a sliding fit between the nozzle plate 12 and an intermediate piece 52 and is held tightly against the intermediate piece 52 by the liquid pressure. A union nut 6 holds the intermediate piece 52 firmly against the end 14 of the housing 5. The fuel is supplied through a bore 7 which is connected to an annular channel 8 at the end of the housing 5. Any fuel leakage is discharged through a line g.

Die Ausführungsform nach Abb. z unterscheidet sich von der Ausführungsform nach Abb. i lediglich durch den Fortfall des Zwischenstückes 52. Das Düsenplättchen 12 ist in diesem Falle mit einem ringförmigen Ansatz versehen, dessen Höhe gleich der Schulter an der Düse 2 ausgebildet ist,The embodiment according to Fig. Z differs from the embodiment according to Fig. i only through the omission of the intermediate piece 52. The nozzle plate 12 is provided in this case with an annular extension, the height of which is the same the shoulder is formed on the nozzle 2,
