Vorteile der Erfindungadvantages the invention
Das erfindungsgemäße Magnetventil mit den Merkmalen des unabhängigen Patentanspruchs 1 hat demgegenüber den Vorteil, dass Zentriermittel vorhanden sind, welche so in einer Innenbohrung des Ventileinsatzes zwischen dem Ventileinsatz und der Rückstellfeder angeordnet sind, dass die Rückstellfeder zentriert und stabilisiert ist. Dadurch kann in vorteilhafter Weise verhindert werden, dass Strömungskräfte, welche auf die Windungen der Rückstellfeder wirken, zu einem seitlichem Ausbrechen der Rückstellfeder führen können, oder die Rückstellfeder von einer Auflage abheben können bzw. die Windungen der Rückstellfeder relativ zueinander in Bewegung bzw. in Schwingungen versetzen können. Insbesondere wird durch die Zentriermittel ein nur axial an einem Ventilkörper anliegendes Federende zentriert und stabilisiert, ohne die Montierbarkeit und Einstellbarkeit des Magnetventils negativ zu beeinflussen.The inventive solenoid valve with the characteristics of the independent Claim 1 has the opposite the advantage that centering means are present, which in one Inner bore of the valve insert between the valve core and the return spring are arranged that the return spring centered and stabilized. This can be done in an advantageous manner prevents flow forces which act on the turns of the return spring, can lead to a lateral breakage of the return spring, or the return spring can stand out from a circulation or the turns of the return spring can move or vibrate relative to each other. Especially is due to the centering a only axially adjacent to a valve body Spring end centered and stabilized, without the mountability and Adjustability of the solenoid valve negative influence.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen und Weiterbildungen sind vorteilhafte Verbesserungen des im unabhängigen Patentanspruch angegebenen Magnetventils möglich.By those in the dependent Claims listed measures and further developments are advantageous improvements of the independent claim specified solenoid valve possible.
Besonders vorteilhaft ist, dass die Zentriermittel als Zentrierhülse mit einem unteren Bund und mindestens zwei vom unteren Bund abgehenden axial verlaufenden Zentrierstegen ausgeführt sind. Der untere Bund ist zwischen einer Stirnfläche des Ventilkörpers und einem Ende der Rückstellfeder angeordnet. Durch die mindestens zwei axialen Zentrierstege kann die Rückstellfeder über eine längere Strecke radial geführt werden, so dass die Rückstellfeder in vorteilhafter Weise nahezu über die gesamte Länge zentriert und stabilisiert wird. Zudem erfordert die Ausführung der Zentriermittel als Zentrierhülse einen kleinen Bauraum und ermöglicht eine gute Durchströmung durch große freie Flächen zwischen den axialen Zentrierstegen. Um die Durchströmung zu verbessern und um den Federeinbauraum nicht zu stark zu reduzieren, wird der untere Bund möglichst dünn und mit einem möglichst großen Außendurchmesser ausgeführt.Especially It is advantageous that the centering means as a centering sleeve a lower waistband and at least two outgoing from the lower waistband axially extending centering webs are executed. The lower fret is between an end face of the valve body and one end of the return spring arranged. By at least two axial centering webs can the return spring over a longer Route guided radially so that the return spring in an advantageous manner almost over the entire length centered and stabilized. In addition, the execution of the requires Centering as centering a small space and allows a good flow through big ones open spaces between the axial centering webs. To improve the flow and not to reduce the spring installation space too strong, the lower waistband as thin as possible and with one possible huge outer diameter executed.
In Ausgestaltung des erfindungsgemäßen Magnetventils enden die mindestens zwei axial verlaufenden Zentrierstege in einem oberen Bund, welcher eine Montageschräge umfasst. Der obere Bund stabilisiert in vorteilhafter Weise die Zentrierstege und verhindert ein Aufbiegen der Zentrierstege durch Querkräfte der Rückstellfeder, welche im Vergleich zu den möglichst dünn ausgeführten Zentrierstegen erheblich sein können. Die Zentrierhülse ist spritzgerecht ausgeführt, so dass eine kostengünstige Herstellung als Kunststoffspritzteil möglich ist.In Embodiment of the solenoid valve according to the invention end the at least two axially extending centering webs in one upper collar, which includes a mounting bevel. The upper fret stabilizes Advantageously, the centering webs and prevents bending the centering webs by lateral forces the return spring, which compared to the possible thin executed Zentrierstegen considerably could be. The centering sleeve is sprayed, so that cost-effective Production as a plastic injection molded part is possible.
In weiterer Ausgestaltung des erfindungsgemäßen Magnetventils sind die Abmessungen der mindestens zwei axialen Zentrierstege in radialer Richtung an den Durchmesser der Rückstellfeder angepasst, wodurch die radiale Führung der Rückstellfeder in vorteilhafter Weise weiter verbessert werden kann. Die Zentrierstege der Zentrierhülse sind für eine optimale Durchströmung der freien Flächen möglichst schmal und in radialer Richtung möglichst dick ausgeführt, um die Rückstellfeder in vorteilhafter Weise gegen deren Querkräfte gut und stabil führen zu können.In a further embodiment of the erfindungsge According solenoid valve, the dimensions of the at least two axial centering webs are adapted in the radial direction to the diameter of the return spring, whereby the radial guidance of the return spring can be further improved in an advantageous manner. The centering webs of the centering sleeve are designed to be as narrow as possible and as thick as possible in the radial direction for optimum flow through the free surfaces in order to be able to guide the return spring in an advantageous manner against its transverse forces well and stably.
Die Zentrierhülse umfasst beispielsweise vier axial verlaufende Zentrierstege, welche vorzugsweise einen mittleren Abstand von 90° zu einander aufweisen, wobei der Ventileinsatz drei Axialnuten aufweist, welche vorzugsweise einen mittleren Abstand von 120° zu einander aufweisen. Die unterschiedliche Anzahl von Zentrierstegen und Axialnuten im Ventileinsatz wird gewählt, um in allen rotatorisch möglichen Einbaupositionen der Zentrierhülse, eine möglichst geringe Überdeckung der Axialnuten im Ventileinsatz zu erzeugen.The centering For example, includes four axially extending centering webs, which preferably have a mean distance of 90 ° to each other, wherein the valve core has three axial grooves, which are preferably a mean distance of 120 ° to have each other. The different number of centering webs and axial grooves in the valve core is chosen to be rotatory in all directions potential Installation positions of the centering sleeve, one preferably low coverage to generate the axial grooves in the valve core.
