Description
Stand der TechnikState of the art
Die Erfindung betrifft ein Magnetventil nach dem Oberbegriff des Anspruchs 1. Ferner betrifft die Erfindung einen Kraftstoffinjektor mit einem erfindungsgemäßen Magnetventil.The invention relates to a solenoid valve according to the preamble of claim 1. Furthermore, the invention relates to a fuel injector with a solenoid valve according to the invention.
Ein Magnetventil nach dem Oberbegriff des Anspruchs 1 ist aus der
Die in einem derartigen Magnetventil bzw. Kraftstoffinjektor herrschenden (System-)Drücke betragen üblicherweise mehr als 1500bar, insbesondere mehr als 2000bar. Zur axialen Beweglichkeit des Magnetankers auf dem Magnetbolzen ist es erforderlich, dass zwischen dem Magnetanker und dem Magnetbolzen ein geringes (radiales) Führungsspiel vorhanden ist. Dieses Führungsspiel ist sowohl druck- als auch temperaturabhängig. Bei einer Druck- oder Temperaturerhöhung kommt es zu einer Vergrößerung des radialen Führungsspalts zwischen der Durchgangsbohrung im Magnetanker und dem Ankerbolzen. Dieses Vergrößern bzw. Aufweiten des Führungsspalts wird zum einen verursacht durch die in radialer Richtung auf den Ankerbolzen wirkenden Druckspannungen, und anderseits durch die auf die Durchgangsbohrung im Magnetanker wirkenden Druckspannungen, die ebenfalls in radialer Richtung wirken. Zusätzlich kommen die Ausdehnungseffekte der Materialien bei einer Temperaturerhöhung zum Tragen. Der erhöhte radiale Führungsspalt zwischen dem Ankerbolzen und der Durchgangsbohrung in dem Magnetventil führt zu einer Vergrößerung der Leckagemenge in Richtung eines Niederdruckbereichs des Magnetventils, die umso größer ist, desto höher der Systemdruck ist. Da eine Vergrößerung der Leckagemenge gleichbedeutend ist mit einer höheren Verlustleistung, die bei einem Kraftstoffinjektor von einer Kraftstoffförderpumpe ausgeglichen werden muss, ist es wünschenswert, die Leckageverluste zu minimieren.The (system) pressures prevailing in such a solenoid valve or fuel injector are usually more than 1500 bar, in particular more than 2000 bar. For the axial mobility of the magnet armature on the magnet pin, it is necessary that a small (radial) guide clearance is present between the magnet armature and the magnet pin. This leadership game is both pressure and temperature dependent. With a pressure or temperature increase, there is an increase in the radial guide gap between the through hole in the armature and the anchor bolt. This enlargement or widening of the guide gap is caused, on the one hand, by the compressive stresses acting in the radial direction on the anchor bolt, and on the other by the compressive stresses acting on the throughbore in the magnet armature, which also act in the radial direction. In addition, the expansion effects of the materials with a temperature increase come into play. The increased radial guide gap between the anchor bolt and the through-hole in the solenoid valve leads to an increase in the leakage amount in the direction of a low-pressure region of the solenoid valve, the larger the higher the system pressure. Since an increase in the leakage amount is equivalent to a higher power loss, which must be compensated in a fuel injector by a fuel delivery pump, it is desirable to minimize the leakage losses.
Offenbarung der ErfindungDisclosure of the invention
Das Magnetventil mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass dessen Leckagemenge im Bereich der Führung zwischen dem Magnetanker und dem Ankerbolzen unabhängig vom herrschenden Druck und/oder der Temperatur auch bei hohen Systemdrücken stets relativ gering ist. The solenoid valve having the features of claim 1 has the advantage that the amount of leakage in the region of the guide between the armature and the anchor bolt is always relatively low regardless of the prevailing pressure and / or temperature even at high system pressures.
Der Erfindung liegt die Idee zugrunde, die Konstruktion des Magnetankers derart gegenüber dem Stand der Technik zu modifizieren, dass der Magnetanker im Bereich seiner Bohrung für den Ankerbolzen zumindest bereichsweise von einem Material mit höherem E-Modul und/oder einem geringeren Wärmeausdehnungskoeffizienten radial, d.h. in Art einer Hülse umgeben ist. Mit anderen Worten gesagt bedeutet dies, dass der Magnetanker im Bereich der Führung für den Ankerbolzen aus zwei unterschiedlichen Materialien besteht, die konzentrisch zueinander angeordnet sind. Dies bewirkt, dass bei einer Druckerhöhung oder bei einer Temperaturerhöhung, welche üblicherweise mit einer Druckerhöhung einhergeht, es zu einer Reduzierung der Aufweitung des Leckagespalts bzw. des Führungsspalts zwischen dem Ankerbolzen und dem entsprechenden Abschnitt der Führungsbohrung des Magnetankers im Vergleich zum Stand der Technik ohne eine Hülse kommt, da die Führungsbohrung des der Magnetanker an einer radialen Ausdehnung tendenziell gehindert wird bzw. diese Ausdehnung reduziert wird.The invention is based on the idea to modify the design of the magnet armature relative to the prior art that the armature in the region of its bore for the anchor bolt at least partially radially of a material with a higher modulus and / or a smaller coefficient of thermal expansion, i. surrounded in the manner of a sleeve. In other words, this means that the armature in the guide for the anchor bolt consists of two different materials, which are arranged concentrically to each other. This causes that at a pressure increase or a temperature increase, which is usually accompanied by an increase in pressure, there is a reduction in the expansion of the leakage gap or the guide gap between the anchor bolt and the corresponding portion of the guide bore of the armature in comparison to the prior art without a Sleeve comes because the guide bore of the magnet armature tends to be prevented at a radial extent or this expansion is reduced.
Vorteilhafte Weiterbildungen des erfindungsgemäßen Magnetventils sind in den Unteransprüchen aufgeführt.Advantageous developments of the solenoid valve according to the invention are listed in the subclaims.
Ganz besonders bevorzugt ist es, wenn der Magnetanker zumindest im Bereich seines hülsenförmigen Abschnitts, der die Führung für den Ankerbolzen ausbildet, aus Stahl und die Hülse, die den Magnetanker in dem hülsenförmigen Abschnitt radial umgibt, aus Hartmetall besteht. Hartmetall hat insbesondere den Vorteil, dass dieses magnetisch nicht wirksam ist und somit den Magnetkreis des Magnetankers nicht beeinflusst. Darüber hinaus ermöglicht es die Verwendung von Hartmetall, die Hülse mit dem Magnetanker nicht nur durch einen Schrumpfprozess, sondern beispielsweise auch durch einen Schweißprozess zu verbinden. Somit wird eine höhere Gestaltungsmöglichkeit bei der möglichen Fertigung des Magnetankers bzw. der Verbindung zwischen der Hülse und dem Magnetanker ermöglicht.It is particularly preferred if the magnet armature consists of hard metal, at least in the region of its sleeve-shaped section which forms the guide for the anchor bolt, made of steel, and the sleeve which radially surrounds the magnet armature in the sleeve-shaped section. Hard metal has the particular advantage that it is not magnetically effective and thus does not affect the magnetic circuit of the armature. Moreover, the use of cemented carbide allows the sleeve to be connected to the magnet armature not only by a shrinking process, but also, for example, by a welding process. Thus, a higher design possibility in the possible production of the magnet armature or the connection between the sleeve and the armature is made possible.
Die Verbindung zwischen dem Magnetanker und der Hülse, kann, wie bereits erläutert, insbesondere entweder durch eine Press- bzw. Schrumpfverbindung, oder durch eine Schweißverbindung erfolgen. Alternativ ist es jedoch auch denkbar, dass der Magnetanker zusammen mit der Hülse als MIM(Metal Injection Moulding)-Bauteil ausgebildet ist. Bei einer derartigen Ausbildung entfällt der Fertigungsschritt des Verbindens zwischen Magnetanker und Hülse.The connection between the magnet armature and the sleeve can, as already explained, be effected in particular either by a press or shrink connection, or by a welded connection. Alternatively, however, it is also conceivable that the magnet armature is formed together with the sleeve as MIM (Metal Injection Molding) component. At a Such training eliminates the manufacturing step of connecting between armature and sleeve.
Die Wirkung der Hülse auf den Magnetanker in Form einer Reduzierung des Führungsspiels bei einer Druckerhöhung lässt sich durch eine entsprechende geometrische Dimensionierung zwischen der Wanddicke des Magnetankers im Bereich der Hülse und der Wanddicke der Hülse (unter Berücksichtigung der verwendeten Materialien für die Hülse und den Magnetanker) beeinflussen. Bei den üblichen Dimensionierungen bzw. Materialien (insbesondere Hartmetall für die Hülse) hat es sich als vorteilhaft erwiesen, wenn die Wanddicke des hülsenförmigen Abschnitts und der Hülse zumindest näherungsweise gleich groß sind.The effect of the sleeve on the armature in the form of a reduction of the guide clearance at a pressure increase can be determined by a corresponding geometric dimensioning between the wall thickness of the armature in the region of the sleeve and the wall thickness of the sleeve (taking into account the materials used for the sleeve and the armature) influence. In the usual dimensions or materials (in particular hard metal for the sleeve), it has proven to be advantageous if the wall thickness of the sleeve-shaped portion and the sleeve are at least approximately equal.
Insbesondere beim axialen Fügen der Hülse auf den hülsenförmigen Abschnitt des Magnetankers ist es zur Gewährleistung bzw. einfachen Sicherstellung der axialen Ist-Position der Hülse von Vorteil, wenn die Hülse axial an einer Stufe des Magnetankers anliegt.In particular, in the axial joining of the sleeve to the sleeve-shaped portion of the armature is to ensure or easy to ensure the axial actual position of the sleeve advantageous if the sleeve rests axially on a step of the armature.
Die Erfindung betrifft auch einen Kraftstoffinjektor unter Verwendung eines erfindungsgemäßen Magnetventils, wobei sich der Kraftstoffinjektor dadurch auszeichnet, dass dieser dazu ausgebildet ist, bei einem Systemdruck von mehr als 2000bar betrieben zu werden. Ein derartiger Systemdruck findet bei selbstzündenden Brennkraftmaschinen in sogenannten Common-Rail-Einspritzsystemen Anwendung.The invention also relates to a fuel injector using a solenoid valve according to the invention, wherein the fuel injector is characterized in that it is designed to be operated at a system pressure of more than 2000bar. Such system pressure is used in self-igniting internal combustion engines in so-called common-rail injection systems.
