Abstract

The electromagnetic valve has a magnetic valve (1) in the form of a 2/2-path magnetic valve open when there is not current. It has a valve rod (11) projecting through a guide shell (12) into a keeper cavity (13) which lies in the diesel oil flow. This cavity is sealed off from the outside by at least one O-ring (16, 17). One end of the rod operates the valve closing body (9) and the other is in active connection with a keeper (18) in the fluid-filled anchor cavity.

Description

Die Erfindung bezieht sich auf ein Elektro-Magnetventil nach der Gattung des Hauptanspruches. Ein derartiges Magnetventil ist bekannt. (EP 0 451 227 B1)The invention relates to an electric solenoid valve according to the genus of Main claim. Such a solenoid valve is known. (EP 0 451 227 B1)

Solche bekannten Elektro-Magnetventile werden meist als stromlos geschlossene Ventile eingesetzt, um die Gefahr des Durchgehens einer Brennkraftmaschine zu verhindern. Solche Magnetventile beanspruchen das Steuergerät verhältnismäßig stark. Das Magnetventil unterbricht den Dieselölstrom von einer Zahnradförderpumpe zur Hochdruckpumpe. Eine derartige Gefahr des Durchgehens besteht zum Beispiel bei einem Verklemmen eines Ringschiebers im Pumpenarbeitsraum, außedem aber auch dann, wenn aufgrund der Spritzverstellung der Förderhub des Hochdruck-Pumpenkolbens bezogen auf seine Drehlage zu spät erfolgt, so daß die Füllnuten bereits im oberen Totpunkt des Pumpenkolbens oder früher die Verbindung zwischen Pumpenarbeitsraum und Saugleitung herstellen.Such known electro-magnetic valves are usually closed when de-energized Valves are used to increase the risk of an internal combustion engine running out prevent. Solenoid valves of this kind require the control unit proportionately strong. The solenoid valve interrupts the flow of diesel oil from a gear pump to the high pressure pump. For example, there is such a risk of runaway if a ring slide is jammed in the pump workspace, besides but also when the delivery stroke of the high-pressure pump piston due to the spray adjustment based on its rotational position too late, so that the filling grooves already at top dead center of the pump piston or earlier the connection between Establish the pump workspace and suction line.

Vorteile der ErfindungAdvantages of the invention

Das erfindungsgemäße Elektro-Magnetventil mit den kennzeichnenden Merkmalen des Hauptanspruches hat demgegenüber den Vorteil, daß das die Ansteuerung durchführende Steuergerät geringer belastet wird, weil das Magnetventil nur im Notfall und zur Funktionskontrolle aktiviert werden muß. Desweiteren ist es von Vorteil, daß der Anker des Magnetventils im Dieselölstrom schwimmt und in einer Messinghülse angeordnet ist, die nach außen, insbesondere zur Spule hin, zuverlässig abgedichtet ist. Weitere Vorteile ergeben sich aus den Merkmalen der Unteransprüche sowie aus der Beschreibung und aus der Zeichnung.The electro-magnetic valve according to the invention with the characteristic features The main claim has the advantage that the control is carried out Control unit is less loaded because the solenoid valve only in an emergency and must be activated for function control. Furthermore, it is advantageous that the armature of the solenoid valve floats in the diesel oil flow and in a brass sleeve is arranged, the outside, especially towards the coil, reliably sealed is. Further advantages result from the features of the subclaims and from the description and the drawing.

    • Beschreibung des AusführungsbeispielsDescription of the embodiment

    Das Magnetventil 1 hat ein gespritztes Kunststoff-Ventilgehäuse 2 mit einem Ventileingang 3 und einem Ventilausgang 4, die beide als Anschlußstutzen für entsprechende Zu- und Ableitungen ausgebildet sind. Außerdem sind am Ventilgehäuse 2 noch eine Aufnahme 5 für einen Elektroanschluß sowie zwei Befestigungslaschen 6 und 7 angebracht.
    Zwischen dem Ventileingang 3 und dem Ventilausgang 4 liegt ein aus Ventilsitz 8 und Ventilschließkörper 9 bestehendes Ventil 10, wobei der Ventilsitz 8 am inneren Ende des Ventileinganges 3 angeformt ist und der Ventilschließkörper 9 eine Kugel ist, die sich dichtend auf den Ventilsitz 8 aufsetzen kann und damit den Durchgang zum Ventilausgang 4 abriegelt.
    Betätigt wird der Ventilschließkörper 9 durch einen Ventilstößel 11, der eine Führungshülse 12 durchdringt und in einen Ankerraum 13 hineinragt. Die Führungshülse 12 hat an ihrer Mantelfläche zwei Ringnuten 14 und 15, in die je ein O-Ring 16 bzw. 17 eingesetzt ist. Der Ankerraum 13 ist mit Dieselöl gefüllt und nimmt einen Anker 18 auf, der auf den Ventilstößel 11 einwirken kann. Der Anker 18 hat eine achsparallel verlaufende Ausgleichsbohrung 19, über die Flüssigkeit von einer Seite auf die andere Seite des Ankers 18 gelangen kann. Nach außen und besonders zu einer Spule 20 hin werden Anker 18 und Ankerraum 13 von einer topfförmigen Messinghülse 21 abgeschlossen, an welcher der eine (16) der beiden O-Ringe 16 und 17 dichtend anliegt.    The solenoid valve 1 has an injection-molded plastic valve housing 2 with a valve inlet 3 and a valve outlet 4, both of which are designed as connecting pieces for corresponding supply and discharge lines. In addition, a receptacle 5 for an electrical connection and two fastening tabs 6 and 7 are attached to the valve housing 2.
    Between the valve inlet 3 and the valve outlet 4 there is a valve 10 consisting of valve seat 8 and valve closing body 9, the valve seat 8 being integrally formed on the inner end of the valve inlet 3 and the valve closing body 9 being a ball which can be seated sealingly on the valve seat 8 and so that the passage to valve outlet 4 is blocked.
    The valve closing body 9 is actuated by a valve tappet 11 which penetrates a guide sleeve 12 and projects into an armature space 13. The guide sleeve 12 has on its outer surface two ring grooves 14 and 15, in each of which an O-ring 16 or 17 is inserted. The armature space 13 is filled with diesel oil and accommodates an armature 18 which can act on the valve lifter 11. The armature 18 has an axially parallel compensation bore 19, through which liquid can pass from one side to the other side of the armature 18. Anchor 18 and armature space 13 are closed off from the outside and particularly towards a coil 20 by a cup-shaped brass sleeve 21, against which one (16) of the two O-rings 16 and 17 lies sealingly.

    Ein Bügel 22 stellt eine magnetische Verbindung her. Ein elektrischer Anschluß 23 dient zur Versorgung der Spule 20. Er ist in das die Einzelteile des Magnetventils 1 umschließende Ventilgehäuse 2 eingebettet, das aus Kunststoff in einem Spritzvorgang hergestellt ist. Durch die Umspritzung ist ein Schutz der Kontaktierung der elektrischen Anschlüsse gegen korrosive Umwelteinflüsse gewährleistet. Außerdem schützt die Umspritzung auch die Spule 20 gegen korrosive Umwelteinflüsse und gegen die besonders in einem Common Rail-System auftretenden Schwingungsbeanspruchungen, indem die einzelnen Drähte fixiert werden und nicht aneinander reiben können.
    Die Befestigung der Führungshülse 12 und der Messinghülse 21 wird erreicht durch ein Umlegen von Laschen, die in den Bügel 22 integriert sind. Der mechanische Zusammenhalt aller feststehenden Ventilteile, die Erstellung der elektrischen und hydraulischen Anschlüsse sowie die Bildung der zwei Befestigungslaschen 6 und 7 werden beim Spritzvorgang zur Herstellung des Kunststoff-Ventilgehäuses 2 erreicht.    A bracket 22 creates a magnetic connection. An electrical connection 23 is used to supply the coil 20. It is embedded in the valve housing 2 enclosing the individual parts of the solenoid valve 1, which is made of plastic in a single injection molding process. The extrusion coating protects the contacting of the electrical connections against corrosive environmental influences. In addition, the extrusion coating also protects the coil 20 against corrosive environmental influences and against the vibration stresses which occur particularly in a common rail system, in that the individual wires are fixed and cannot rub against one another.
    The attachment of the guide sleeve 12 and the brass sleeve 21 is achieved by folding tabs that are integrated in the bracket 22. The mechanical cohesion of all fixed valve parts, the creation of the electrical and hydraulic connections and the formation of the two fastening tabs 6 and 7 are achieved during the injection molding process for the production of the plastic valve housing 2.

    WirkungsweiseMode of action

    Das Elektro-Magnetventil 1 ist in eine Förderleitung von einer nicht dargestellten Zahnrad-Hochdruckpumpe zu einer ebenfalls nicht gezeigten Common Rail-Hochdruckpumpe eingesetzt. Zum Unterbrechen des Dieselölstroms zwecks Abschaltung des Common Rail-Dieselmotors in Notfällen oder für Prüfzwecke wird das Magnetventil 1 aus seiner normalen Offenstellung in Schließstellung geschaltet. Dabei arbeitet es als 2/2-Wege-Magnetventil.The electro-magnetic valve 1 is in a delivery line from a not shown Gear high-pressure pump to a common rail high-pressure pump, also not shown used. To interrupt the diesel oil flow for the purpose of switching off of the common rail diesel engine in emergencies or for testing purposes Solenoid valve 1 switched from its normal open position to the closed position. Here it works as a 2/2-way solenoid valve.

    Die Kraft zum Schließen eds Magnetventils 1 wird durch eine Bestromung der Spule 20 und durch ein entsprechendes Magnetfeld erzeugt. Der magnetische Fluß wird über den Bügel 22, die Führungshülse 12 und den Anker 18 geleitet. Der Anker 18 wird dabei in Richtung Führungshülse 12 gezogen. Er drückt über den Ventilstößel 11 auf den Ventilschließkörper 9 und bewegt diesen auf seinen Ventilsitz 8. Wenn das Ventil 10 geschlossen ist, wird der Dieselölstrom zur Hochdruckpumpe unterbrochen.The force to close the solenoid valve 1 is generated by energizing the coil 20 and generated by a corresponding magnetic field. The magnetic flux will passed over the bracket 22, the guide sleeve 12 and the armature 18. The anchor 18th is pulled towards the guide sleeve 12. He presses over the valve lifter 11 on the valve closing body 9 and moves it to its valve seat 8. If the valve 10 is closed, the diesel oil flow to the high pressure pump is interrupted.

    Beim Anschalten der Bestromung werden der Ventilschließkörper 9, der Ventilstößel 11 und der Anker 18 durch den geringeren hydraulischen Druck der Förderpumpe zurückgeschoben, und das Magnetventil 1 öffnet wieder. Im Inneren des Magnetventils 1 herrscht dann der geringe Druck, den die Förderpumpe erzeugt, etwa 2 bar. Die Abdichtung des Ankerraumes 13 nach außen erfolgt über die zwei O-Ringe 16 und 17 und über die Führungshülse 12 zum Ventilgehäuse 2 hin. Die weitere Abdichtung wird über die Führungshülse 12, den O-Ring 16 und die Messinghülse 21 bewerkstelligt.When the current supply is switched on, the valve closing body 9, the valve tappet 11 and the armature 18 are pushed back by the lower hydraulic pressure of the feed pump, and the solenoid valve 1 opens again. Inside the solenoid valve 1 then there is the low pressure that the feed pump generates, about 2 bar. The Sealing of the armature space 13 to the outside takes place via the two O-rings 16 and 17 and over the guide sleeve 12 to the valve housing 2. The further sealing is accomplished via the guide sleeve 12, the O-ring 16 and the brass sleeve 21.

    Das stromlos offene Schaltprinzip hat den Vorteil, daß das die elektrischen Schaltvorgänge überwachende elektronische Steuergerät nur gering belastet wird und zwar nur im Notfall oder zur Funktionskontrolle. Desweiteren ist durch diese Art der Betätigung der Vorteil gegeben, daß dadurch, daß in der Abstellstellung der Magnet die höchste Kraft hat, eine optimale Ausnutzung der magnetischen Energie gewährleistet ist. The currentless open switching principle has the advantage that this is the electrical switching operations monitoring electronic control unit is only slightly loaded and that only in an emergency or for a functional check. Furthermore, this type of activity the advantage given that the fact that in the parking position of the magnet has the highest power, ensures optimal use of magnetic energy is.
