Das beschriebene herkömmliche stromlos offene Magnetventil hat die Aufgabe sehr dosiert den Druck in einem Fluidsystem zu modulieren, wobei ein sehr geringer Druckabbaugradient, d. h. ein kleiner Durchfluss gefordert wird. Daher sollten hydraulische Magnetventile auch bei sehr kleinen Hüben des Schließelements durch die Magnetgruppe stetig einstellbar sein. Ein stabiler Arbeitspunkt ist dadurch gekennzeichnet, dass ein Kräftegleichgewicht zwischen öffnenden und schließenden Kräften besteht. Weiter sollte das System bei Störungen wieder in den Arbeitspunkt zurückfinden. Bei dem beschriebenen herkömmlichen stromlos offenen Magnetventil ist eine stetige Einstellbarkeit in Arbeitspunkten mit sehr kleinen Hüben aufgrund ihrer hydraulischen und magnetischen Charakteristik sehr schwierig.The described conventional normally open solenoid valve has the task of very metered pressure in a fluid system, with a very low pressure drop gradient, d. H. a small flow is required. Therefore, should hydraulic solenoid valves even with very small strokes of the closing element be continuously adjustable by the magnet group. A stable operating point is characterized in that an equilibrium of forces between opening and closing forces consists. Further, the system should return to the operating point in the event of faults find back. In the described conventional normally open solenoid valve is a steady adjustability in Working points with very small strokes due to their hydraulic and magnetic characteristics very difficult.
Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Magnetventil mit den Merkmalen des unabhängigen Patentanspruchs 1 hat demgegenüber den Vorteil, dass ein Hauptventil elastische Dichtmittel mit einer bekannten Elastizität aufweist, durch welche eine kontrollierte Leckage und sehr geringe Druckabbaugradienten ermöglicht werden, so dass sehr kleine Fluidflüsse realisiert werden können, ohne von den hydraulischen und magnetischen Charakteristika des Magnetventils abhängig zu sein. Durch eine gezielte Verformung der elastischen Dichtmittel und die dadurch bewirkten sich ändernden Anpressverhältnisse und kleinste Veränderungen des Öffnungsquerschnitts des Hauptventils, kann der Fluidfluss durch das geschlossene Hauptventil als Leckage gezielt beeinflusst werden. So sind selbst kleinste Druckabbaugradienten möglich. Zudem weist das Magnetventil in vorteilhafter Weise einen stabi len Zustand auf, da bei dem geschlossenen Hauptventil immer ein Kontakt zwischen dem Hauptdichtelement und dem Hauptventilsitz besteht. Bei herkömmlichen stromlos offenen Magnetventilen bedeutet eine Leckage des Hauptventils ein unkontrollierter Druckverlust mit einem sehr geringen Gradienten durch ein nicht vollständig schließendes Hauptventil. Die Leckage des Hauptventils tritt in der Regel auf, wenn der Schließstrom durch eine Magnetspule des Magnetventils nicht hoch genug ist. Im erfindungsgemäßen Magnetventil können hingegen durch eine kontrollierte Leckage des Hauptventils sehr geringe Druckabbaugradienten und damit kleine Durchflüsse realisiert werden, ohne von den hydraulischen und magnetischen Charakteristiken des Magnetventils abhängig zu sein.The inventive solenoid valve with the characteristics of the independent Claim 1 has the opposite the advantage that a main valve elastic sealant with a has known elasticity, through which a controlled leakage and very low pressure reduction gradient be made possible so that very small fluid flows can be realized without from the hydraulic and magnetic characteristics of the Solenoid valve dependent to be. By a targeted deformation of the elastic sealant and the resulting changes Anpressverhältnisse and the smallest changes of the opening cross-section of the main valve, the fluid flow through the closed main valve be specifically influenced as leakage. So are even the smallest Pressure reduction gradient possible. In addition, the solenoid valve advantageously has a stabi len Condition on, since with the closed main valve always a contact between the main seal member and the main valve seat. In conventional normally open solenoid valves means a leakage of the main valve an uncontrolled pressure drop with a very low gradient by a not complete closing main valve. The leakage of the main valve usually occurs when the closing current through a solenoid of the solenoid valve is not high enough. In the solenoid valve according to the invention can however, by a controlled leakage of the main valve very realized low pressure reduction and thus small flow rates be without the hydraulic and magnetic characteristics of the solenoid valve dependent to be.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen und Weiterbildungen sind vorteilhafte Verbesserungen des im unabhängigen Patentanspruch 1 angegebenen Magnetventils möglich.By those in the dependent Claims listed measures and further developments are advantageous improvements of the independent claim 1 specified solenoid valve possible.
Besonders vorteilhaft ist, dass die elastischen Dichtmittel des geschlossenen Hauptventils durch den Anpressdruck bzw. die Anpresskraft des Hauptdichtelements im Hauptventilsitz gezielt verformbar sind, wobei der Anpressdruck bzw. die Anpresskraft durch eine entsprechende Bestromung der Magnetbaugruppe über die erzeugte Magnetkraft einstellbar ist und fein dosiert werden kann. Somit verändert sich durch die Variation des Anpressdrucks bzw. der Anpresskraft die Verformung der elastischen Dichtelemente des Hauptventils, so dass in vorteilhafter Weise ein kleiner Fluidfluss als kontrollierte Leckage eingestellt werden kann.It is particularly advantageous that the elasti rule by the contact pressure or the contact pressure of the main sealing element in the main valve seat are selectively deformable rule, the contact pressure or the contact pressure by an appropriate energization of the magnet assembly on the generated magnetic force is adjustable and can be finely dosed. Thus, the deformation of the elastic sealing elements of the main valve is changed by the variation of the contact pressure or the contact pressure, so that advantageously a small fluid flow can be set as a controlled leakage.
In Ausgestaltung des erfindungsgemäßen Magnetventils sind die elastischen Dichtmittel beispielsweise im Bereich der Dichtlinie am Hauptdichtelement des Schließelements angeordnet. Alternativ können die elastischen Dichtmittel im Bereich der Dichtlinie am Hauptventilsitz im Ventilkörper angeordnet werden. Die elastischen Dichtmittel können beispielsweise mehrere Segmente umfassen, die beabstandet zueinander angeordnet sind.In Embodiment of the solenoid valve according to the invention For example, the elastic sealing means are in the region of the sealing line on the main sealing element of the closing element arranged. Alternatively you can the elastic sealant in the region of the sealing line on the main valve seat in the valve body to be ordered. The elastic sealing means may for example several Include segments which are spaced from each other.
In alternativer Ausgestaltung des erfindungsgemäßen Magnetventils ist das Hauptdichtelement als elastisches Dichtmittel ausgeführt und aus einem elastischen Material hergestellt. Bei Verwendung des Hauptdichtelements aus einem elastischen Material, wie beispielsweise Polyehteretherketon (PEEK), kann dessen Verformbarkeit zur Einstellung einer kontrollierten Leckage ausgenutzt werden. Das aus einem elastischen Material herge stellte Hauptdichtelement weist beispielsweise mindestens eine gezielt eingebrachte Unrundheit und/oder Unebenheit auf, die zur Einstellung der kontrollierten Leckage durch den eingestellten Anpressdruck bzw. die eingestellte Anpresskraft ausgeglichen werden können.In Alternative embodiment of the solenoid valve according to the invention is the main sealing element as elastic sealant executed and made of an elastic material. When using the main sealing element of an elastic material, such as polyetheretherketone (PEEK), its ductility for adjusting a controlled Leakage be exploited. The presented from an elastic material Herge Main sealing element has, for example, at least one deliberately introduced Out-of-roundness and / or unevenness on the setting of the controlled Leakage due to the set contact pressure or the set contact pressure can be compensated.
In weiterer Ausgestaltung des erfindungsgemäßen Magnetventils kann die Elastizität der elastischen Dichtmittel in vorteilhafter Weise durch eine gezielte Materialauswahl vorgegeben werden.In Another embodiment of the solenoid valve according to the invention, the elasticity the elastic sealing means in an advantageous manner by a targeted Material selection can be specified.
