Die Erfindung betrifft eine Hochdruckpumpe für ein Kraftstoffsystem einer Brennkraftmaschine mit mindestens einer Einlassventileinrichtung mit einem Ventilelement, einem Ventilsitz für das Ventilelement und einem Betätigungsstößel, der das Ventilelement zwangsweise in eine Öffnungsrichtung drücken kann.The The invention relates to a high-pressure pump for a fuel system Internal combustion engine with at least one inlet valve device with a valve element, a valve seat for the valve element and a Actuator tappet, the Forcibly can push the valve element in an opening direction.
Es ist bekannt, Hochdruckpumpen mit derartigen Einlassventileinrichtungen, die auch als Mengensteuerventile bezeichnet werden, auszuführen. Derartige bekannte Mengensteuerventile weisen Mittel zur genauen radialen Führung eines Betätigungsstößels auf und umfassen üblicherweise ein Ventilelement mit Flachsitz. Außerdem können sie zur Beeinflussung einer Förderrate der Hochdruckpumpe durch Bestromung einer elektromagnetischen Betätigungseinrichtung zwangsweise in einer Offenstellung gehalten bzw. in eine solche gebracht werden. Derartige Mengensteuerventile werden daher auch als stromlos geschlossene Mengensteuerventile bezeichnet.It is known, high-pressure pumps with such inlet valve devices, which are also referred to as quantity control valves to execute. such known quantity control valves have means for accurate radial guide an actuating tappet on and usually include a valve element with flat seat. In addition, they can influence a funding rate the high pressure pump by energizing an electromagnetic actuator Forcibly held in an open position or in such an open position to be brought.

Offenbarung der ErfindungDisclosure of the invention
Aufgabe der Erfindung ist es, eine Hochdruckpumpe für ein Kraftstoffsystem einer Brennkraftmaschine zu schaffen, die noch kostengünstiger herstellbar ist und einen geringeren Verschleiß und somit eine höhere Lebensdauer aufweist.task The invention is a high pressure pump for a fuel system To provide internal combustion engine, which is even cheaper to produce and less wear and therefore a higher one Life has.
Diese Aufgabe wird durch eine Hochdruckpumpe mit Merkmalen des Anspruchs 1 gelöst.These Task is achieved by a high pressure pump with features of the claim 1 solved.
Vorteilhafte Weiterbildungen sind in Unteransprüchen genannt. Für die Erfindung wichtige Merkmale gehen ferner aus der nachfolgenden Beschreibung und der Zeichnung hervor, wobei die Merkmale allein oder in unterschiedlichen Kombinationen wichtig sein können, ohne dass hierauf nochmals explizit hingewiesen wird.advantageous Further developments are mentioned in subclaims. For the invention important features will become more apparent from the following description and the drawing, wherein the features alone or in different Combinations can be important without being explicitly mentioned again.
Bei der Realisierung der erfindungsgemäßen Hochdruckpumpe wird durch die genauere Positionierung des Ventilelements gegenüber dem Ventilsitz ein gleichmäßigerer Fluidstrom am gesamten Umfang des Ventilelements erzielt. Dies führt zu einer geringeren Verwirbelung eines am Ventilelement vorbeifließenden Kraftstoffes, so dass sich ein höherer Durchfluss bei geöffneter Einlassventileinrichtung ergibt.at the realization of the high-pressure pump according to the invention is through the more accurate positioning of the valve member over the Valve seat a more uniform Fluid flow achieved over the entire circumference of the valve element. This leads to a lower one Turbulence of a fuel flowing past the valve element, so that a higher flow rate when open Inlet valve device results.
Hierbei ist besonders bevorzugt, dass die Positionierungsmittel einen am Ventilelement vorhandenen balligen, vorzugsweise kugelsegmentartigen ersten Kontaktbereich umfassen. Eine kugelartige Form des Ventilelements ermöglicht eine Verringerung der Strömungsumlenkung bei geöffneter Einlassventileinrichtung, so dass die Durchflussrate weiter erhöht werden kann. Ferner lassen sich mit Hilfe eines balligen beziehungsweise kugelsegmentförmigen Kontaktbereichs die Positionierungsmittel besonders einfach realisieren. Es brauchen insbesondere keine zusätzlichen Bauteile vorgesehen zu werden.in this connection is particularly preferred that the positioning means a on Valve element existing spherical, preferably spherical segment-like include first contact area. A spherical shape of the valve element allows a reduction in the flow deflection when open Inlet valve device, so that the flow rate can be further increased can. Furthermore, can be with the help of a crowned or spherical segment Contact area the positioning means particularly easy to implement. In particular, no additional components are required to become.
Andererseits kann auch vorgesehen werden, dass die Positionsmittel einen am Ventilelement vorhandenen konischen ersten Kontaktbereich umfassen. Auf diese Weise kann eine einfach, schnell und kostengünstig herstellbare Hochdruckpumpe bereitgestellt werden.on the other hand can also be provided that the position means one on the valve element comprise existing conical first contact area. To this Way can be a simple, fast and inexpensive to produce high pressure pump to be provided.
Ferner ist bevorzugt, dass die Positionierungsmittel einen am Ventilsitz vorhandenen zweiten Kontaktbereich umfassen, der zu dem ersten Kontaktbereich komplementär und/oder konisch ausgebildet ist. Dadurch wird ein zuverlässiges und reproduzierbares Schließen der Einlassventileinrichtung bei geringem Verschleiß und somit einer hohen Dauerfestigkeit erreicht. Werden der erste Kontaktbereich des Ventilelements ballig und der zweite Kontaktbereich des Ventilsitzes konisch ausgebildet, sind aufwändige Fertigungsschritte, wie beispielsweise Schleifvorgänge, nicht unbedingt erforderlich.Further it is preferred that the positioning means one on the valve seat existing second contact area, which to the first contact area complementary and / or is conical. This will be a reliable and reproducible closing the inlet valve device with little wear and thus achieved a high fatigue strength. Be the first contact area the valve element crowned and the second contact region of the valve seat conical, are elaborate Manufacturing steps, such as grinding operations, not absolutely necessary.
Der Betätigungsstößel kann in einem Gehäuse der Einlassventileinrichtung oder der Hochdruckpumpe mit radialem Spiel "fliegend" gelagert sein. Es wird also auf eine genaue radiale Führung des Betätigungsstößels verzichtet, was die Herstellung vereinfacht. Dadurch ergibt sich aufgrund einer Verringerung einer Reibung eine bessere Beweglichkeit des Betätigungsstößels in axialer Richtung und somit eine schnell schaltende Einlassventileinrichtung. Des Weiteren werden die für die radiale Führung erforderlichen Bauteile entbehrlich, so dass die Teilezahl und somit die Herstellkosten der Hochdruckpumpe reduziert werden.Of the Actuator can in a housing the inlet valve device or the high-pressure pump with radial Game "flying" be stored. It is therefore dispensed with an accurate radial guidance of the actuating plunger, which simplifies the production. This results due to a reduction a friction better mobility of the actuating plunger in the axial direction and thus a fast switching inlet valve device. Furthermore, will be the for the radial guidance Required components dispensable, so that the number of parts and thus the manufacturing costs of the high-pressure pump can be reduced.
Es kann vorgesehen werden, dass der Betätigungsstößel und das Ventilelement zwei separate Teile sind, die zumindest bei zwangsweise in Öffnungsrichtung gedrücktem Ventilelement mittels radial wirkender Fixiermittel zueinander radial fixiert sind. Die Ausgestaltung durch zwei separate Teile erleichtert die Fertigung dieser Teile und ihre Montage. Dennoch wird vermieden, dass sich bei zwangsweise geöffneter Einlassventileinrichtung das Ventilelement und der Betätigungsstößel relativ zueinander dezentrieren. Eine gleichmäßige Umströmung des Ventilelements ist also nicht nur bei selbsttätig geöffneter, sondern auch bei zwangsweise geöffneter Einlassventileinrichtung gewährleistet.It can be provided that the actuating plunger and the valve element two separate parts are, at least when forced in the opening direction depressed Valve element by means of radially acting fixing means to each other radially are fixed. The design facilitated by two separate parts the manufacture of these parts and their assembly. Nevertheless, it avoids that when forced open Inlet valve means the valve element and the actuating plunger relative decenter each other. A uniform flow around the valve element is so not only with self-acting opened, but even with forced open Inlet valve device ensures.
Die radialen Fixiermittel können einen Zapfen an einem Teil und eine komplementäre Ausnehmung am anderen Teil umfassen. Dies stellt eine zuverlässig arbeitende und verschleißarme Realisierungsform der Fixiermittel dar. Die Herstellung ist besonders einfach, wenn der Zapfen am Betätigungsstößel und die komplementäre Ausnehmung am Ventilelement vorgesehen wird.The radial fixing means may have a pin on one part and a complementary recess include on the other part. This is a reliable working and low-wear implementation of the fixing means. The preparation is particularly simple when the pin is provided on the actuating plunger and the complementary recess on the valve element.
Es ist besonders bevorzugt, dass Zapfen und Ausnehmung konisch sind. Derartige Fixiermittel lassen sich nämlich besonders einfach herstellen und arbeiten dennoch zuverlässig, da eine aufgetretene Dezentrierung sicher beseitigt werden kann.It is particularly preferred that pin and recess are conical. Such fixatives can namely be produced particularly easily and still work reliably, since an occurred decentration can be safely eliminated.
Wird vorgesehen, dass die Hochdruckpumpe an einem vom Ventilelement abgewandten Ende des Betätigungsstößels eine Dämpfungsfeder aufweist, dann wird ein harter Anschlag des Betätigungsstößels beim Schließen der Ventileinrichtung vermieden. Dies führt zu einer weiteren Verringerung des Verschleißes und von Betriebsgeräuschen.Becomes provided that the high-pressure pump facing away from the valve element End of the actuating tappet one damping spring has, then a hard stop of the actuating plunger when closing the Valve device avoided. This leads to a further reduction of the wear and operating noise.
Hierbei ist besonders bevorzugt, dass an einer von dem Betätigungsstößel abgewandten Seite des Ventilelements eine Ventilfeder angeordnet ist, welche das Ventilelement in Schließrichtung beaufschlagt, und dass die Dämpfungsfeder und die Ventilfeder derart zusammenwirken, dass eine Bewegung des Betätigungsstößels in Schließrichtung zumindest ab einem bestimmten Resthub gedämpft wird. Durch eine solche Abstimmung der Dämpfungsfeder und der Ventilfeder wird ein zuverlässiges Schließen der Ventileinrichtung, das heißt das Aufsitzen des Ventilelements auf dem Ventilsitz, gewährleistet, und zugleich die Rücklaufbewegung des Betätigungsstößels beim Schließen der zunächst zwangsweise geöffneten Einlassventileinrichtung gedämpft.in this connection is particularly preferred that on a side facing away from the actuating plunger Side of the valve element, a valve spring is arranged, which the valve element in the closing direction charged, and that the damping spring and the valve spring cooperate such that movement of the Actuating tappet in closing direction is dampened at least from a certain residual stroke. By such Tuning the damping spring and the valve spring will reliably close the Valve device, that is the seating of the valve element on the valve seat, ensures and at the same time the return movement of the actuating tappet during Shut down the first compulsory open Inlet valve device damped.
