Die Erfindung betrifft ein elektromagnetisch betätigbares Saugventil für eine Hochdruckpumpe in einem Kraftstoffeinspritzsystem, insbesondere einem Common- Rail- Einspritzsystem, mit den Merkmalen des Oberbegriffs des Anspruchs 1. Ferner betrifft die Erfindung eine Hochdruckpumpe für ein Kraftstoffeinspritzsystem, insbesondere ein Common-Rail-Einspritzsystem, mit einem solchen Saugventil.

Furthermore, the invention relates to a high pressure pump for a fuel injection system, in particular a common rail injection system, with such a suction valve.

Stand der Technik State of the art

Hochdruckpumpen in einem Kraftstoffeinspritzsystem dienen der Förderung von Kraftstoff auf Hochdruck. Hierzu weist eine Hochdruckpumpe mindestens ein Pumpenelement mit einem Hochdruck-Elementraum auf, in dem der Kraftstoff komprimiert wird. Der auf Hochdruck geförderte Kraftstoff wird anschließend über einen Hochdruckabgang einem Hochdruckspeicher, dem so genannten Rail, zugeführt. Die Befüllung des Hochdruck-Elementraums erfolgt in der Regel über ein Saugventil, das beispielsweise als elektromagnetisch betätigbares Ventil ausgelegt sein kann. Dieses wird derart angesteuert, dass dem Hochdruck-Elementraum eine definierte Kraftstoffmenge zugeführt wird. High-pressure pumps in a fuel injection system serve to deliver fuel to high pressure. For this purpose, a high-pressure pump has at least one pump element with a high-pressure element space, in which the fuel is compressed. The fuel delivered for high pressure is then fed via a high-pressure outlet to a high-pressure accumulator, the so-called rail. The filling of the high pressure element space is usually via a suction valve, which may be designed, for example, as an electromagnetically operable valve. This is controlled such that the high-pressure element space a defined amount of fuel is supplied.

Ein elektromagnetisch betätigbares Saugventil besitzt in der Regel eine Magnethülse, welche eine Magnetspule umgibt. Die Magnethülse ist bereichsweise mit einem Kunststoffmaterial umspritzt, um eine Abdichtung zu bewirken und die erforderlichen elektri- sehe Anschlusselemente zu verwahren. Zur Verbindung eines elektromagnetisch betätigbaren Saugventils mit einer Hochdruckpumpe wird üblicherweise eine Überwurfmutter verwendet, die sich auf der Magnethülse abstützt und einen Kragen an einem Gehäuseteil der Hochdruckpumpe umgreift. Zur Abstützung der Überwurfmutter ist an der Magnethülse ein Wulst ausgebildet, der einen erhöhten Aufwand bei der Herstellung der Magnethülse erfordert. Dies wiederum wirkt sich negativ auf die Herstellungskosten des Saugventils aus. An electromagnetically actuated suction valve usually has a magnetic sleeve which surrounds a magnetic coil. The magnetic sleeve is partially encapsulated with a plastic material to effect a seal and the required electrical store connection elements. To connect an electromagnetically actuated suction valve with a high-pressure pump usually a union nut is used, which is supported on the magnet sleeve and engages around a collar on a housing part of the high-pressure pump. To support the nut a bead is formed on the magnet sleeve, which requires an increased effort in the manufacture of the magnet sleeve. This in turn has a negative effect on the manufacturing cost of the suction valve.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein elektromagnetisch betätigbares Saugventil für eine Hochdruckpumpe anzugeben, dass einfach und kostengünstig herstellbar ist. Ferner soll der Anbau an einer Hochdruckpumpe vereinfacht werden. The present invention has for its object to provide an electromagnetically actuated suction valve for a high-pressure pump that is simple and inexpensive to produce. Furthermore, the cultivation of a high-pressure pump should be simplified.

Zur Lösung der Aufgabe werden das elektromagnetisch betätigbare Saugventil mit den Merkmalen des Anspruchs 1 sowie eine Hochdruckpumpe mit einem solchen Saugventil vorgeschlagen. Darüber hinaus wird ein Verfahren zur Verbindung eines solchen Saugventils mit einem Gehäuseteil einer Hochdruckpumpe angegeben. Vorteilhafte Weiterbildungen der Erfindung sind den jeweiligen Unteransprüchen zu entnehmen. To solve the problem, the electromagnetically actuated suction valve with the features of claim 1 and a high-pressure pump with such a suction valve are proposed. In addition, a method for connecting such a suction valve with a housing part of a high pressure pump is specified. Advantageous developments of the invention can be found in the respective subclaims.

Offenbarung der Erfindung Disclosure of the invention

Das zur Befüllung eines Hochdruck-Elementraums einer Hochdruckpumpe mit Kraftstoff vorgeschlagene elektromagnetisch betätigbare Saugventil umfasst eine Magnetspule zur Einwirkung auf einen hubbeweglichen Anker, der unmittelbar oder mittelbar mit einem hubbeweglichen Ventilkolben koppelbar ist. Die Magnetspule ist dabei zumindest abschnittsweise von einer Magnethülse umgeben. Zur Reduzierung der Herstellungskosten ist die Magnethülse als kostengünstiges Tiefziehteil ausgeführt. Dies ist möglich, da auf die Ausbildung einer umlaufenden Wulst zur Abstützung einer Überwurfmutter verzichtet wird. Darüber hinaus besitzt die Magnethülse einen Endabschnitt zur Verbindung mit einem Gehäuseteil einer Hochdruckpumpe, so dass ferner die Überwurfmutter entfallen kann. Der Entfall eines Bauteils wirkt sich ebenfalls kostensenkend aus. Bevorzugt besitzt der Endabschnitt der Magnethülse einen Innendurchmesser, der gegenüber dem Innendurchmesser der Magnethülse vergrößert ist. Der Endabschnitt vermag demnach einen Kragen aufzunehmen, der üblicherweise an einem Gehäuseteil einer Hochdruckpumpe zur Verbindung mit einer Überwurfmutter vorgesehen ist. Vor- zugsweise ist im Bereich der Vergrößerung des Innendurchmessers ein umlaufenderThe electromagnetically actuated suction valve proposed for filling a high-pressure element space of a high-pressure pump with a fuel comprises a magnetic coil for acting on a liftable armature, which can be coupled directly or indirectly with a liftable valve piston. The magnetic coil is at least partially surrounded by a magnetic sleeve. To reduce the cost of the magnetic sleeve is designed as a cost-effective deep-drawn part. This is possible because it dispenses with the formation of a circumferential bead for supporting a union nut. In addition, the magnetic sleeve has an end portion for connection to a housing part of a high-pressure pump, so that further the union nut can be omitted. The elimination of a component also has a cost-reducing effect. Preferably, the end portion of the magnet sleeve has an inner diameter which is enlarged relative to the inner diameter of the magnet sleeve. The end portion is therefore capable of receiving a collar, which is usually provided on a housing part of a high-pressure pump for connection to a union nut. Preferably, in the region of the enlargement of the inner diameter is a circumferential

Absatz ausgebildet, über den sich die Magnethülse am Kragen abstützen kann. Formed paragraph over which the magnetic sleeve can be supported on the collar.

Des Weiteren bevorzugt ist der Anker in Richtung des Ventilkolbens von der Federkraft einer Druckfeder beaufschlagt, deren Federkraft größer als die Federkraft einer Ventil- kolbenfeder ist, die entgegengesetzt in Schließrichtung auf den Ventilkolben wirkt. DasFurther preferably, the armature is acted upon in the direction of the valve piston by the spring force of a compression spring, the spring force of which is greater than the spring force of a valve piston spring, which acts counter to the valve piston in the closing direction. The

Saugventil ist demnach bevorzugt als stromlos offenes Ventil ausgelegt. Wird die Magnetspule bestromt, bildet sich ein Magnetfeld aus, dessen Magnetkraft bewirkt, dass sich der Anker entgegen der Federkraft der Druckfeder vom Ventilkolben weg bewegt. Dadurch wird der Ventilkolben entlastet und die Ventilkolbenfeder vermag den Ventil- kolben in seinen Sitz zu ziehen. Das Ventil schließt und die Befüllung des Hochdruck-Suction valve is therefore preferably designed as a normally open valve. If the magnetic coil is energized, forms a magnetic field whose magnetic force causes the armature against the spring force of the compression spring moves away from the valve piston. As a result, the valve piston is relieved and the valve piston spring is able to pull the valve piston into its seat. The valve closes and the filling of the high pressure

Elementraums mit Kraftstoff wird unterbrochen. Zum Öffnen des Ventils wird die Bestromung der Magnetspule beendet. In der Folge wird der Anker durch die Federkraft der Druckfeder in seine Ausgangslage zurückgestellt, wobei der Anker den Ventilkolben entgegen der Federkraft der Ventilkolbenfeder aus seinem Sitz hebt. Die Kopp- lung des Ankers mit dem Ventilkolben kann dabei mechanisch durch direkten Kontakt erfolgen, so dass der Bauraumbedarf des Saugventils gering ist. Ferner können die Herstellungskosten gesenkt werden, da nur wenige Bauteile erforderlich sind. Element space with fuel is interrupted. To open the valve, the energization of the solenoid is terminated. As a result, the armature is returned by the spring force of the compression spring in its initial position, wherein the armature lifts the valve piston against the spring force of the valve piston spring from its seat. The coupling of the armature with the valve piston can be done mechanically by direct contact, so that the space requirement of the suction valve is low. Furthermore, the manufacturing cost can be reduced because only a few components are required.

Die ferner zur Lösung der eingangs genannten Aufgabe vorgeschlagene Hochdruck- pumpe für ein Kraftstoffeinspritzsystem, insbesondere ein Common- Rail-The further proposed high-pressure pump for a fuel injection system, in particular a common rail

Einspritzsystem, umfasst neben einem erfindungsgemäßen elektromagnetisch betätigbaren Saugventil ein Gehäuseteil, das einen hohlzylinderförmigen Kragen besitzt, der in den Endabschnitt der Magnethülse des Saugventils eingreift. Die Verbindung zwischen dem Saugventil und der Hochdruckpumpe wird demnach direkt über die Magnethülse hergestellt, so dass eine Überwurfmutter entfallen kann. Dies wirkt sich wiederum günstig auf die Herstellungskosten der Hochdruckpumpe aus. Injection system, in addition to an electromagnetically actuated suction valve according to the invention comprises a housing part which has a hollow cylindrical collar which engages in the end portion of the magnet sleeve of the suction valve. The connection between the suction valve and the high pressure pump is therefore made directly on the magnet sleeve, so that a nut can be omitted. This in turn has a favorable effect on the production costs of the high-pressure pump.

Bevorzugt besitzt der Kragen eine umlaufende Ringnut, in die ein nach radial innen verformtes Ende des Endabschnitts der Magnethülse des Saugventils eingreift. Das in die Ringnut des Kragens eingreifende Ende des Endabschnitts der Magnethülse bewirkt eine formschlüssige Verbindung, so dass das Saugventil sicher am Gehäuseteil der Hochdruckpumpe befestigt ist. Preferably, the collar has a circumferential annular groove, in which engages a radially inwardly deformed end of the end portion of the magnet sleeve of the suction valve. This in the annular groove of the collar engaging end of the end portion of the magnet sleeve causes a positive connection, so that the suction valve is securely fixed to the housing part of the high-pressure pump.

Ferner wird vorgeschlagen, dass der Kragen eine Abstützfläche besitzt, an welcher der umlaufende Absatz der Magnethülse des Saugventils unmittelbar oder mittelbar axial abgestützt ist. Durch die axiale Abstützung ist das Saugventil in seiner axialen Lage zum Gehäuseteil der Hochdruckpumpe fixiert. In radialer Richtung kann eine Lagefixierung dadurch bewirkt werden, dass das radiale Spiel zwischen dem Endabschnitt der Magnethülse und dem Kragen minimiert ist. Zudem wird eine Fixierung in radialer Richtung über das verformte Ende des Endabschnitts erreicht, das in die Ringnut des Kragens eingreift. It is also proposed that the collar has a support surface on which the peripheral shoulder of the magnet sleeve of the suction valve is supported directly or indirectly axially. Due to the axial support, the suction valve is fixed in its axial position to the housing part of the high-pressure pump. In the radial direction, a positional fixation can be effected in that the radial clearance between the end portion of the magnet sleeve and the collar is minimized. In addition, a fixation in the radial direction over the deformed end of the end portion is achieved, which engages in the annular groove of the collar.

Vorteilhafterweise ist zwischen dem Kragen und einem Ventilteil des Saugventils, das in den Kragen hineinragt, ein Dichtelement angeordnet. Das Dichtelement stellt die Abdichtung nach Außen sicher. Advantageously, a sealing element is arranged between the collar and a valve part of the suction valve which projects into the collar. The sealing element ensures the seal to the outside.

Ferner wird ein Verfahren zur Verbindung eines erfindungsgemäßen elektromagnetisch betätigbaren Saugventils mit einem einen hohlzylinderförmigen Kragen aufweisenden Gehäuseteil einer Hochdruckpumpe vorgeschlagen. Bei diesem Verfahren wird die Magnethülse des Saugventils derart auf den Kragen aufgesetzt, dass der Endabschnitt der Magnethülse den Kragen umgreift. Dabei gelangt vorzugsweise ein umlaufender Absatz der Magnethülse in Anlage mit einer am Kragen ausgebildeten Abstützfläche, durch welche die axiale Lage des Saugventils in Bezug auf das Gehäuseteil der Hochdruckpumpe vorgegeben ist. Anschließend wird der Endabschnitt endseitig derart verformt, dass er in eine umlaufende Ringnut des Kragens eingreift. Das heißt, dass ein Formschluss bewirkt wird, der eine sichere Befestigung des Saugventils am Furthermore, a method for connecting a solenoid-operated suction valve according to the invention with a hollow cylindrical collar having housing part of a high-pressure pump is proposed. In this method, the magnetic sleeve of the suction valve is placed on the collar in such a way that the end portion of the magnetic sleeve engages around the collar. Preferably, a peripheral shoulder of the magnet sleeve comes into contact with a support surface formed on the collar, by which the axial position of the suction valve is predetermined with respect to the housing part of the high-pressure pump.

Bevorzugt wird der Endabschnitt der Magnethülse durch Prägen oder Bördeln endseitig verformt. Mit diesen Umformverfahren lässt sich die Verformung des Endabschnitts zur Herstellung des Formschlusses einfach und kostengünstig durchführen. Eine bevorzugte Ausführungsform eines erfindungsgemäßen elektromagnetisch betätigbaren Saugventils wird nachfolgend anhand der beigefügten Zeichnung näher erläutert. Die Zeichnung stellt einen schematischen Längsschnitt durch ein erfindungsgemäßes Saugventil dar, das an eine Hochdruckpumpe angebaut ist. Preferably, the end portion of the magnet sleeve is deformed by embossing or flanging end. With these forming methods, the deformation of the end portion for producing the positive connection can be performed easily and inexpensively. A preferred embodiment of an electromagnetically actuated suction valve according to the invention will be explained in more detail with reference to the accompanying drawings. The drawing shows a schematic longitudinal section through an inventive suction valve, which is attached to a high-pressure pump.

Ausführliche Beschreibung der Zeichnung Detailed description of the drawing

Das schematisch dargestellte Saugventil 1 dient der Befüllung eines Hochdruck- Elementraums 2 einer Hochdruckpumpe mit Kraftstoff. Es ist hierzu in Bezug auf den Hochdruck-Elementraum 2 axial an die Hochdruckpumpe in der Weise angebaut, dass ein hubbeweglicher Ventilkolben 5 des Saugventils 1 in den Hochdruck-Elementraum 2 hinein öffnet. The suction valve 1 shown schematically serves to fill a high pressure element space 2 of a high pressure pump with fuel. For this purpose, in relation to the high-pressure element space 2, it is mounted axially on the high-pressure pump in such a way that a lift-movable valve piston 5 of the suction valve 1 opens into the high-pressure element space 2.

Zur Betätigung des Saugventils 1 weist dieses eine Magnetspule 3 auf, die auf einen hubbeweglichen Anker 4 einwirkt, der mit dem Ventilkolben 5 mechanisch gekoppelt ist. Wird die Magnetspule 3 bestromt, bildet sich ein Magnetfeld aus, dessen Magnetkraft den Anker 4 entgegen der Federkraft einer Druckfeder 10 in Richtung eines Polkerns 18 bewegt, um einen Arbeitsluftspalt 19 zu schließen. Dadurch wird der Ventilkolben 5 entlastet, so dass eine den Ventilkolben 5 in Schließrichtung beaufschlagende Ventilkolbenfeder 11 diesen in einen Sitz 20 zieht. Mit Beendigung der To actuate the suction valve 1, this has a magnetic coil 3, which acts on a liftable armature 4, which is mechanically coupled to the valve piston 5. If the magnetic coil 3 is energized, forms a magnetic field whose magnetic force moves the armature 4 against the spring force of a compression spring 10 in the direction of a pole core 18 to close a working air gap 19. As a result, the valve piston 5 is relieved, so that a valve piston 5 acting in the closing direction valve piston spring 11 pulls this into a seat 20. With termination of

Bestromung der Magnetspule 3 wird der Anker 4 über die Druckfeder 10 in seine Ausgangslage zurückgestellt, wobei er den Ventilkolben 5 aus dem Sitz 20 hebt. Das Saugventil 1 ist demnach als stromlos offenes Ventil ausgebildet. Energization of the solenoid 3, the armature 4 is returned via the compression spring 10 in its initial position, wherein it lifts the valve piston 5 from the seat 20. The suction valve 1 is therefore designed as a normally open valve.

Die Magnetspule 3 ist von einer Magnethülse 6 umgeben, mittels welcher das Saugventil 1 zugleich an einem Gehäuseteil 8 der Hochdruckpumpe befestigt ist. Die Magnethülse 6 weist hierzu einen dem Gehäuseteil 8 zugewandten Endabschnitt 7 auf, der einen vergrößerten Innendurchmesser besitzt und einen hohlzylinderförmigen Kragen 12 des Gehäuseteils 8 umgreift. Ein Ende 14 des Endabschnitts 7 ist dabei derart verformt, dass er in eine umlaufende Ringnut 13 des Kragens 12 eingreift. Dadurch wird ein Formschluss bewirkt, der eine sichere Befestigung gewährleistet. The magnetic coil 3 is surrounded by a magnetic sleeve 6, by means of which the suction valve 1 is at the same time attached to a housing part 8 of the high-pressure pump. For this purpose, the magnet sleeve 6 has an end section 7 facing the housing part 8, which has an enlarged inner diameter and surrounds a hollow cylindrical collar 12 of the housing part 8. One end 14 of the end portion 7 is deformed such that it engages in a circumferential annular groove 13 of the collar 12. As a result, a positive connection is effected, which ensures a secure attachment.

Der Kragen 12 weist eine Abstützfläche 15 auf, an der ein Ventilteil 16 des Saugventils 1 abgestützt ist. Zwischen dem Ventilteil 16 und dem Kragen 12 ist ein Dichtele- ment 17 in Form eines Dichtrings eingelegt, das der Abdichtung nach Außen dient. Zur Abstützung am Kragen 12 weist das Ventilteil 16 einen sich nach radial außen erstreckenden Bund 21 auf, der zugleich in den Endabschnitt 7 der Magnethülse 6 eingreift. Dabei kommt ein umlaufender Absatz 9 der Magnethülse 6 auf dem Bund 21 des Ven- tilteils 16 zu liegen. Mittelbar über das Ventilteil 16 ist somit auch die Magnethülse 6 an der Abstützfläche 15 des Kragens 12 in axialer Richtung abgestützt. The collar 12 has a support surface 15 on which a valve part 16 of the suction valve 1 is supported. Between the valve member 16 and the collar 12 is a sealing ment 17 inserted in the form of a sealing ring, which serves to seal to the outside. For support on the collar 12, the valve member 16 has a radially outwardly extending collar 21, which engages in the end portion 7 of the magnet sleeve 6 at the same time. In this case, a circumferential shoulder 9 of the magnet sleeve 6 comes to rest on the collar 21 of the valve part 16. Thus indirectly, the magnet sleeve 6 is supported on the support surface 15 of the collar 12 in the axial direction indirectly via the valve member 16.

Die Befestigung des Saugventils 1 an dem Gehäuseteil 8 der Hochdruckpumpe über die Magnethülse 6 macht eine Überwurfmutter entbehrlich. Zudem ist die Magnethül- se 6 in der dargestellten Ausgestaltung als kostengünstiges Tiefziehteil herstellbar, denn Verdickungen, beispielsweise zur Ausbildung einer Wulst, welche die Abstützung einer Überwurfmutter ermöglichen würde, sind nicht erforderlich. Die als Tiefziehteil hergestellte Magnethülse 6 senkt demnach nicht nur die Herstellungskosten des erfindungsgemäßen Saugventils 1, sondern vereinfacht ferner den Anbau des Saugven- tils 1 an einer Hochdruckpumpe. The attachment of the suction valve 1 to the housing part 8 of the high pressure pump via the magnet sleeve 6 makes a union nut unnecessary. In addition, the magnet sleeve 6 in the illustrated embodiment can be produced as a cost-effective deep-drawn part, because thickenings, for example for the formation of a bead, which would enable the support of a union nut, are not required. Accordingly, the magnetic sleeve 6 produced as a deep-drawn part not only reduces the manufacturing costs of the suction valve 1 according to the invention, but also simplifies the mounting of the suction valve 1 on a high-pressure pump.
