Description

Einblaseventil, insbesondere für naschlaufende Verbrennungskraftmaschinen, mit nach innen gerichteter Öffnungsbewegung. Gegenstand vorliegender Erfindung ist ein Einblaseventil, :insbesondere für naschlaufende Verbrennu.ngskraftmaschinen. Sie betrifft Ventile solcher Art, bei denen die Nadel eine nach dem Zylinderinnern: gerichtete Offnünwbewegnrng ausführt.Injection valve, especially for slow-moving internal combustion engines, with inward opening movement. The present invention is an injection valve, especially for slow-moving internal combustion engines. It concerns valves of the type in which the needle is one after the inside of the cylinder: Directed open movement executes.

Die Vorteile dieser Ventilart sind bekannt. Bei den bisher bekannt gewordenen Ausführungen :bestehen diese ldarin,, :daß .sie -wie andere Ventile mit gewöhnlicher Sehwinghebelanordnung angetrieben -werden ;können Lind` daß der innere Überdruck im Zvlinder nicht entgegen dem Nadelsch:ließdruck, sondern vielmehr unterstützend im Schließungssinne wirkt.The advantages of this type of valve are known. Known so far The following versions exist: do they consist in: that they -like other valves with conventional rocker arm arrangement -be driven; Lind` that the inner Overpressure in the cylinder is not against the needle pressure, but rather supportive acts in the sense of closure.

Diesem Vorteil steht der schwerwiegende Nachteil entgegen, daßdiese nach innen öffnenden Einbla.se:v entile nur sehr schwer zugänglich sind und zum Zweck der Reinigung vollständig vom Zylinder und den Rohrleitungen getrennt werden müssen.This advantage is countered by the serious disadvantage that this inward opening inlets: valves are very difficult to access and for Be completely separated from the cylinder and the piping for the purpose of cleaning have to.

Erfrrndlungcgemäß wird dieser Nachteil vermieden und! ein einwandfrei zugängliches Ventil,dies-er Artgeschaffen, indemn der Ventiasitz, die Naldelführung, die Nadelstopfbüchse und der Zerstäuber einem gemeinsamen, vom eigentlichen Ventilgehäuse leicht lösbaren Körper zugehören. Dabei ist es besonders vorteilhaft, wenn Druckluft- und Brennstoffleitung am Ventilgehäuse angeschlossen sind, so daß sich der Einsatzkörper entfernen läßt, ohne daß @d#iese Leitungen abgenommen werden. Die notwendige Lösung der Ventilfeder wird, sehr vereinfacht und erleichtert, wenn :die Ventilfeder einerseits an ,der Ventilspindel leicht lösbar befestigt ist und sich anderseits unmittelbar gegen das Ventilg ehäuse außerhalb des Ventileinisatzkörpers abstützt.According to the invention, this disadvantage is avoided and! a flawless accessible valve of this kind created by the valve seat, the naldel guide, the needle gland and the atomizer share a common, from the actual valve housing belong to easily detachable bodies. It is particularly advantageous if compressed air and fuel line are connected to the valve housing so that the insert body can be removed without removing these lines. The necessary solution the valve spring is very simplified and facilitated when: the valve spring on the one hand on, the valve spindle is easily detachably attached and on the other hand directly is supported against the valve housing outside the valve insert body.

In der Zeichnung ist als Au@s@führungs!beispiel ein Ventil im Mittelschnitt dargestellt. Das @-en.ti:lgehäuse a, ist in die Zylinderwand b eingeschraubt. In' :das Gehäuse a ist das im wesentlichen rohrförmige, als Ventilführung dienende Einsatzstück e eingesetzt. Seine A!tddchtung ge:äen das GelLiuse a .erfolgt durch die konischen Auflageflächen f und f1. Eis (besitzt .eine Bohrung cl, (die die Verlängerung der Bohrung c im Ventilgehäuse a bildet und die zur Druckluftzuleitungdient. Die Verbindung des Einsatzstückes c mit :dem Gehäuse a erfolgt mittels der Ringmutter g, welche mit Außengewinde in das Gehäulse a eingescAiraubt ist unid die konischen Flächen f, fl am Einsatzstfc,lc gegen die entsprechenden Flächen des Gehäuses a preßt.In the drawing, a valve is shown in the middle section as a design example shown. The @ -en.ti: oil housing a is screwed into the cylinder wall b. In' : The housing a is the essentially tubular insert serving as a valve guide e used. Its seal against the gel is made by the conical Support surfaces f and f1. Ice (possesses a bore cl, (which is the extension of the Bore c forms in the valve housing a and which is used for the compressed air supply line. The connection of the insert c with: the housing a takes place by means of the ring nut g, which The conical surfaces are screwed into the housing with an external thread f, fl on the insert stfc, lc presses against the corresponding surfaces of the housing a.

.Den E:insetz'körper e durchdringt der Ventilschaft 1a auf seiner ganzen Länge. Zur --'#.bdiehtung zwischen ihm und dem Körper c dient die Stopflbüchsenmutter i. Der Ventilkegel k wird durch d4e -Feder l gegen seinen Sitz gepreßt. Gegen den Federteller va, der an dem@ Ventilschaft la leicht lösbar befestigt ist, stützt sich die Druckfeder 1, deren entgegengesetztes Ende auf einem Bunld: n des Gehäuses a liegt. Nach Abnahme des Federtellers m und der Feder 1 kann die Mutter g gelöst werden, worauf das Ventil 1a samt der Stopfbüchse i, (dem Fü'hrungs'Ikörper e und den aus mehreren Ringplatten o bestehenden Zerstäuberkörper ohne weiteres abgenommen werden kann. Die Platten o sitzen in dem Hohlraum zwischen. Ventilgehäuse und Einsatzkörper und liegen auf !dessen Bund p auf. Um sie leicht auswechseln ,zu können, sind sie zweiteilig ausgeführt. Der Brennstoff wird durch die Bohrung d im Ventilgehäuse zugeführt.The valve stem 1a penetrates the E: insert body e along its entire length. The stuffing box nut i is used to tighten between it and the body c. The valve cone k is pressed against its seat by d4e spring l. The compression spring 1, the opposite end of which lies on a bundle of the housing a, rests against the spring plate va, which is easily detachably attached to the valve stem la. After removing the spring plate m and the spring 1 , the nut g can be loosened, whereupon the valve 1a together with the stuffing box i, (the guide body e and the atomizer body consisting of several ring plates o can be easily removed sit in the cavity between the valve housing and the insert body and rest on its collar p. In order to be able to replace them easily, they are designed in two parts. The fuel is supplied through the bore d in the valve housing.
