Description

Elektromagnetisch betätigtes Ventil Elektromagnetisch betätigte Ventile, -welche nach dem Solenoidprinzip arbeiten, sind seit langem bekannt. Bei der Verwendung diesec Ventile für größere lichte Durchgänge und höhere Drücke kann zwar die Ventilspule beliebig groß gemacht werden, praktisch zeigt sieh jedoch, daß die aufgenommenen Leistungen sowie die äußeren Abmessungen bei oben erwähnten - Betriebsverhältnissen, außergewöhnlich groß werden.Electromagnetically Operated Valve Electromagnetically Operated Valves, -which work according to the solenoid principle have long been known. When using Diesec valves for larger clear passages and higher pressures can be made by the valve spool can be made arbitrarily large, but practically shows that the recorded Performances as well as the external dimensions under the above-mentioned operating conditions, become exceptionally large.

Um an sich schon größere Querschnitte bewältigen zu können, ist es bekannt, den, Ventilkegel, welcher elektromagnetisch betätigt wird, in einen großen und einen kleinen Ventilkegel zu unterteilen mit dem Zweck, durch öffnen des kleinen Ventilseine Druckentlastung hinter dem großen Ventilkegel: hervorzurufen und so dessen Betätigung zu erleichtern.In order to be able to cope with larger cross-sections, it is known, the valve cone, which is actuated electromagnetically, in a large and to subdivide a small valve cone with the purpose of opening the small one Valve's pressure relief behind the large valve cone: to evoke and so on to facilitate its operation.

Die vorliegende Erfindung befaßt sich mit einem Ventil der zuletzt erwähnten Bauart, also einem Ventil; welches L elektromagnetisch; betätigt -wird und' zwecks leichterer Betätigung einen Haupt- und einen Hilfsventilkegel besitzt. Um auch bei derartigen Venölen mit gleichbleibender Leistung größere Ventilquerschnitte und Arbeitsdrücke bewältigen zu können, wurde ein Ventil gebaut, bei dem der Magnetpol N einen axial beweglichen Hilfspol A enthält, der gegenüber dem als Ventilkegel K und H ausgebildeten Anker durch eine Feder F abgesützt ist und der bei Stromschluß gegen den durch den Innendruck auf dem Sitz festgehaltenen Ventilkegel K bewegt wird, worauf der Ventilkegel H, nachdem der Hilfspol A mit dem Ventilkegel K in Anlage oder annähernd in Anlage gekommen ist; angehoben -wird, der Innendruck durch eine Bohrung O sieh ausgleicht, um dann gemeinsam mit dem Ventilkegel K nach. oben in den Pol N eingezogen zu werden.The present invention is concerned with a valve of the last-mentioned type, that is to say a valve; which L electromagnetic; is actuated and 'has a main and an auxiliary valve cone for easier actuation. In order to be able to cope with larger valve cross-sections and working pressures even with such venous oils with constant power, a valve was built in which the magnetic pole N contains an axially movable auxiliary pole A, which is supported by a spring F against the armature designed as valve cones K and H and which is moved against the valve cone K held by the internal pressure on the seat when the current is closed, whereupon the valve cone H after the auxiliary pole A has come into contact with or approximately in contact with the valve cone K; is raised, the internal pressure is equalized through a bore O, and then together with the valve cone K afterwards. to be drawn into the pole N at the top.

Durch diese Bauart wird erreicht, daß trotz eines dem Ventilquerschnitt entsprechenden großen Hubes des Ventils nur ein kleiner Luftspalt zwischen Pol. und Anker vorhanden ist und so die größtmögliche Anzugskraft ausgeübt werden kann. In der Zeichnung bezeichnen: A einen Hilfspol., F die den Hilfspol abstützende Feder, H den kleineren Ventilkegel, K den größeren Ventilkegel, L den zwischen dem später erwähnten Spulengehäuse !11 und dem größeren Ventilkegel K Luft- spalt, !f1 das Spulengehäuse, N den 1 gnetpol, O eine Durchflußöffnung in kleineren Ventilkegel H, S die Betätig' s spule. Die Wirkungsweise ist folgende: Sog bei Kontaktgabe durch die Spule S Strom fließt und sich das magnetische Feld über das Spulengehäuse l11, Luftspalt L, Ventilkegel H und K, über Luft zum Magnetpol N bnv. Hilfspol _1 gebildet hat, bewegt sich der Hilfspol A auf die Ventilkegel I( und H zu; um den kleinsten Widerstand im Magnetkreis zu erzielen. Dieselbe Bewegung wäre von den Ventilkegeln H und IST zu erwarten. Diese sind jedoch durch den. sich hinter ihnen befindlichen Druck des; Durchflußmediums festgehalten. Sobald sich der Hilfspol.4 ganz oder angenähert im Anschlag mit dem größeren Ventilkegel I( befindet. ist der Luftspalt zwischen dem Hilfspol A und dem kleineren Ventilkegel H so klein geworden, daß die ausgeübte Kraft auf den Ventilkegel K genügend groß ist, diesen anzulieben. Über die f')ffnung O kann sich nurt,-mehr der sich hinter den Ventilkegeln H und h' befindliche Druck in die Ausflußöffnung des Ventils ausgleichen, so daß der Ventilkegel K einseitig druckbelastet ist, da der Druck von der Zuflußseite des Ventils auf den Ventilkegel K wirkt und sich über das Spiel I_ nicht rasch genug ausgleichen kann. Durch diesen einseitigen Druck und zusätzlich durch die wirkende magnetische Kraft werden alsdann Ventilkegel H und K gemeinsam finit dein Hilfspol A in den Ma- netpol N eingezogen. Wird der Strom rch die Spule S unterbrochen, drückt die f er F die Ventilkegel H und K gemein- in ihre Schlußstellung zurück. This design ensures that, despite a large valve stroke corresponding to the valve cross-section, only a small air gap between the pole. and anchor is available so that the greatest possible tightening force can be exerted. In the drawing: A denotes an auxiliary pole, F the spring supporting the auxiliary pole, H the smaller valve cone, K the larger valve cone, L the air between the later mentioned coil housing 11 and the larger valve cone K gap,! f1 the bobbin case, N den 1 gnetpol, O a flow opening in smaller valve cone H, S the actuators kitchen sink. The mode of action is as follows: suction When contact is made through the coil S, current flows and the magnetic field spreads via the coil housing l11, air gap L, valve cone H and K, via air to the magnetic pole N bnv. Auxiliary pole _1 has formed, auxiliary pole A moves towards valve cones I (and H; in order to achieve the lowest resistance in the magnetic circuit. The same movement would be expected from valve cones H and IST. However, these are due to the one behind them As soon as the auxiliary pole 4 is completely or approximately in the stop with the larger valve cone I (. The air gap between the auxiliary pole A and the smaller valve cone H has become so small that the force exerted on the valve cone K is sufficient The pressure behind the valve cones H and h 'can only be equalized into the outflow opening of the valve via the f') opening O, so that the valve cone K is pressure-loaded on one side, since the pressure from the inflow side of the valve acts on the valve cone K and cannot compensate itself quickly enough via the clearance I. Due to this one-sided pressure and additionally due to the acting magnet Then the valve cone H and K jointly become finite your auxiliary pole A in the dimensions netpol N pulled in. Will the current When the coil S is interrupted, the presses for F the valve cones H and K in common back to their final position.
