Klaus Matthos, Freiberg Klaus Läffler, Thalheim Gerhard Haase, Karl-Marx-Stadt Verfahren zum Ansteuern von elektromagnetischen Ventilen mit zwei Magnetsystemen, insbesondere für Brennstofi-Einspritzventile von Brennkraitnaschinon.Klaus Matthos, Freiberg Klaus Läffler, Thalheim Gerhard Haase, Karl-Marx-Stadt Method for controlling electromagnetic valves with two magnet systems, especially for fuel injection valves from Brennkraitnaschinon.

Die Erfindung betrifft ein Verfahren zum Absteuern von elektromagnetischen Ventilen mit zwei Magnet systemen, insbesondere für Einspritzventile von Brennkraftmschinen.The invention relates to a method for switching off electromagnetic Valves with two magnet systems, especially for injection valves of internal combustion engines.

Bekannt ist es, die Ansprechzeitigen von Magnetventilen durch Verringerung der durch die Magnetkraft bewegten Massen, durch Vergrößern der Flächen, an denen die Magnetkraft angreift und durch Verringerung der Induktivität der Arbeitswicklung gering zu halten. Weiterhin ist ein Verfahren zum Verringern der Ansprechzeit von Magnetventilen bekannt, bei den die Arbeitswicklung des Magnetventils vor oder nach Jeder Betätigung durch eine Wechselspannung mit vorgewählter Frequenz entmagnetisiert wird.It is known to reduce the response times of solenoid valves of the masses moved by the magnetic force, by enlarging the areas on which the magnetic force attacks and by reducing the inductance of the working winding to keep it low. Furthermore, a method for reducing the response time of Solenoid valves known in which the working winding of the solenoid valve before or after Every time it is actuated, it is demagnetized by an alternating voltage with a preselected frequency will.

Bei allen diesen Verfahren sind Schließfedern notwendig, die mit ihrer Kraft ein schnelles Schlieren sichern müssen. Das ist nachteilig.In all of these processes, closing springs are necessary to match their Force must ensure a quick streak. That is disadvantageous.

Aufgabe der Erfindung -ist es, ein Verfahren Zum Ansteuern von elektromagnetisch gesteuerten Ventilen mit zwei Magnetsystemen zu schaffen, welches es gestattet, auch bei kurzen Öffnungszeiten ein exaktes öffnen bzw. Schließen des Ventils zu ermöglichen, insbesondere soll keine wesentliche Kraft zur Vorspannung des Systens in einer der Endlagen benötigt werden.The object of the invention is to provide a method for controlling electromagnetically to create controlled valves with two magnet systems, which allows exact opening and closing of the valve even with short opening times enable, in particular, no essential Force to preload of the system are required in one of the end positions.

Erfindungsgemäß wird die Autgabe dadurch gelöst, daß zwei entgegengesetzt wirkende Elektromagnetsysteme in der Weise angesteuert sind, daß das stromführende, in der Folge jedoch abzuschaltende Öffnungs-Magnetsystem erst dann stromlos wird, wenn das abgeschaltete und das in der Folge eingeschaltete Schließ-Magnetsystem seinen max. Strom bzw, einen hohen Prozentsatz dessen erreicht hat.According to the invention, the task is achieved in that two opposite acting electromagnetic systems are controlled in such a way that the current-carrying, as a result, however, the opening magnet system that is to be switched off only becomes de-energized, when the shut-off magnet system and the one subsequently switched on has reached its maximum current or a high percentage of it.

Dabei weist das Öffnungs-Magnetsystem eine höhere Stel kraft als das Schließ-Magnetsystem auf.The opening magnet system has a higher actuating force than that Closing magnet system.

Erfindungsgemäß kann den Schließ-Magnetsystem eine Feder parallel geschaltet sein, deren Wirkungsrichtung gleich der dea Schließ-Magnetsystems ist.According to the invention, the closing magnet system can have a spring in parallel be switched, whose direction of action is the same as that of the closing magnet system.

Vorteilhaft ist bei diesem Verfahren, daß unabhängig von don Stromverlauf und dem Aufbau des Magnetfeldes durch die sich ergebenden Kräfteverhältnisse ein genau zu detialerender Öffnungs- und Schließzeitpunkt für das elektromagnetische Ventil erzielbar ist.The advantage of this method is that regardless of the current course and the build-up of the magnetic field through the resulting balance of forces opening and closing times for the electromagnetic Valve is achievable.

An Hand eines Ausführungsbeispieles soll das Verfahren erläutert werden.The method is to be explained using an exemplary embodiment.

Es zeigt: Fig. 1: Ein Brennstoff-Einspritsventil mit zwei Drehmagnet systemen, Fig. 2: die Kraft-, Stromkurven von Öffnungs- und Schließmagnetsystem in ihrer zeitlichen Folge.It shows: FIG. 1: A fuel injection valve with two rotary solenoids systems, Fig. 2: the force and current curves of the opening and closing magnet system in their chronological order.

Das elektromagnetische Ventil 1 wird bei dem vorliegenden Verfahren durch das Öffnungs-Magnetsystem 2 entgegen einer sehr schwachen Feder 31 geöffnet und durch die Kraft des Schließ-Magnetsystems 3 praktisch ausschließlich geschlossen.The electromagnetic valve 1 is used in the present method opened by the opening magnet system 2 against a very weak spring 31 and practically exclusively closed by the force of the closing magnet system 3.

In Pig. 2a ist die Stromkurve des Schließmagnetsystems 3 und in Fig. 2b die Stromkurve des Öffnungs-Magnetsystems gezeigt. Die Stellungen der Stromkurven zueinander entsprechen der zeitlichen Folge.In Pig. 2a is the current curve of the closing magnet system 3 and in Fig. 2b shows the current curve of the opening magnet system. The positions of the current curves to each other correspond to the chronological sequence.

Bei Stromlosigkeit der Magnetsysteme 2; 3 hält nur die sehr schwache Feder 31 das Ventil 1 geschlossen. Entscheidend ist, daß das Öffnungs-Magnetsystem 2 erst da= abgeschal#tet wird, wenn das Schließ-Magnetsystem 3 seinen vollen Strom und damit seine volle Kraft erreicht hat und das Öffnungs-Magnetsystem 2 nur gegen die geringe Federkraft der Schließfeder 31 wirkt.If the magnet systems 2; 3 only holds the very weak one Spring 31 the valve 1 is closed. It is crucial that the opening magnet system 2 is only switched off when the closing magnet system 3 has its full current and thus has reached its full force and the opening magnet system 2 only against the low spring force of the closing spring 31 acts.

Dieses Verfahren kann auf alle elektromagnetischen Ventilbauarten mit zwei entgegengesetzt wirkenden Magnetsystenen angewandt werden, wobei Jedoch nur solche Konstruktionen in Betracht kommen, in denen die Steuerorgane des Ventils druckentlastet sind.This procedure can be applied to all types of electromagnetic valves with two oppositely acting magnet systems can be used, however only those constructions come into consideration, in which the control elements of the valve are relieved of pressure.
