Description
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 TechnikState 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 elektrische 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 to store the required electrical 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 ErfindungDisclosure 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.The proposed for filling a high-pressure element space of a high-pressure pump with fuel electromagnetically actuated suction valve comprises a magnetic coil for acting on a liftable armature, which is directly or indirectly coupled to 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.
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. Vorzugsweise ist im Bereich der Vergrößerung des Innendurchmessers ein umlaufender Absatz ausgebildet, über den sich die Magnethülse am Kragen abstützen kann.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, a circumferential shoulder is formed, 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 Ventilkolbenfeder ist, die entgegengesetzt in Schließrichtung auf den Ventilkolben wirkt. Das 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 Ventilkolben in seinen Sitz zu ziehen. Das Ventil schließt und die Befüllung des Hochdruck-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 Kopplung 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.Further preferably, the armature is acted upon in the direction of the valve piston by the spring force of a compression spring whose spring force is greater than the spring force of a valve piston spring, which acts in the closing direction opposite to the valve piston. The 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 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. Further The manufacturing costs can be reduced, since only a few components are required.
Die ferner zur Lösung der eingangs genannten Aufgabe vorgeschlagene Hochdruckpumpe für ein Kraftstoffeinspritzsystem, insbesondere ein 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.The further proposed for the solution of the above-mentioned object high pressure pump for a fuel injection system, in particular a common rail 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. The engaging in the annular groove of the collar 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 Gehäuseteil der Hochdruckpumpe gewährleistet.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 circumferential 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. Subsequently, the end portion is deformed end side such that it engages in a circumferential annular groove of the collar. That is, a positive connection is effected, which ensures a secure attachment of the suction valve on 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.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.
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.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.
