Description
Die Erfindung betrifft elektromagnetisch ansteuerbare Mehrstrahleinspritzdüsen, vorzugsweise für Verbrennungsmotoren mit zwei Ansaugkanälen pro Zylinder, gemäß dem Oberbegriff des Hauptanspruchs 1.The The invention relates to electromagnetically controllable multi-jet injection nozzles, preferably for internal combustion engines with two intake channels per Cylinder, according to the generic term of the main claim 1.
Vorbekannt

die Schrift
Der Erfindung liegt die Aufgabe zugrunde, elektromagnetisch ansteuerbare Mehrstrahleinspritzdüsen mit teilweise einzeln aufsteuerbaren Spritzkanälen mit wenig unterschiedlicher Dichtsitzfläche und einem leichteren zweiten Ventilkörper zu versehen. Erfindungsgemäß wird dies durch die im kennzeichnenden Teil des Hauptanspruchs angegebenen Merkmale erreicht.Of the Invention is based on the object electromagnetically controllable Multibeam injectors with partially individually controllable spray channels with little difference Sealing seat and to provide a lighter second valve body. According to the invention this is by the features stated in the characterizing part of the main claim reached.
Die Kugel der zweiten Dichtanordnung kann einen ähnlich bemessenen Sitz wie die Ventilnadel aufweisen. Beim Ausheben der Kugel durch radiales Verlagern aus dem kegeligen Sitz müssen die in Nadelhubrichtung resultierenden Kräfte, die wirkende Kraft der sie belastenden Feder und die vom Kraftstoffdruck auf die Kugel ausgeübte Kraft überwunden werden.The Ball of the second sealing arrangement may have a similar sized seat have the valve needle. When lifting the ball by radial displacement from the conical seat need the forces resulting in Nadelhubrichtung, the acting force of they stressing the spring and the fuel pressure on the ball practiced Force to be overcome.
Im geöffneten Zustand ist nur noch die in Nadelhubrichtung als resultierenden Kräfte wirkende Kraft der die Kugel belastenden Feder auszugleichen. Wesentlich ist bei zunehmendem Nadelhub nur der Kraftanstieg der die Ventilnadel belastenden Feder. Diese Verhältnisse ermöglichen, den Haltestrom des Elektromagneten bei geöffneten Ventileinrichtungen herabzusetzen, obwohl zum unmittelbaren Öffnen der zweiten Ventileinrichtung eine markant höhere Magnetkraft notwendig ist. Der Kräftesprung sichert ein sauberes Ansteuern auch nur der ersten Ventileinrichtung.in the open Condition is only in Nadelhubrichtung as resulting personnel compensate for the acting force of the ball loading spring. Essential is with increasing needle stroke only the increase in force of the valve needle stressing spring. These relationships enable, the holding current of the electromagnet with open valve devices reduce, although for immediate opening of the second valve device a significantly higher Magnetic force is necessary. The force jump ensures a clean Driving only the first valve device.
In der nachfolgenden Beschreibung wird die Ausführung der erfindungsgemäßen Mehrstrahldüse und deren Ausgestaltungen gemäß der Unteransprüche anhand einer Zeichnung erläutert.In the following description will be the execution of the multi-jet nozzle according to the invention and their Embodiments according to the subclaims explained a drawing.
