Abstract
Description
Gegenstand der Erfindung ist ein Wegeventil entsprechend dem Oberbegriff des ersten Patentanspruchs.The invention relates to a directional control valve according to the preamble of the first claim.
Wegeventile mir zwei Schaltstellungen und einer Mehrzahl von Anschlüssen sind bekannt und weit verbreitet, ebenso sind durch einen Elektromagneten betätigte Wegeventile bekannt. Solche Wegeventile sind in der Regel mit zylindrischen Schiebern ausgestattet. Sie erlauben, mit recht geringen Kräften auch große Durchflüsse zuverlässig zu schalten. Außerdem sind Kugelhähne bekannt, die mittels eines Hebels verstellt werden und in Abhängigkeit vom Drehwinkel der Kugel im Zusammenwirken mit dem Gehäuse Kanäle in der Kugel freigeben oder verschließen. Als Sitzventile sind linearwirkende Ventile bekannt, die bedingt abdichtende Kugeln enthalten, sie eignen sich für hohe Drücke und für kleine Durchflüsse.Directional control valves with two switching positions and a plurality of terminals are known and widely used, as well as actuated by an electromagnet directional control valves are known. Such directional valves are usually equipped with cylindrical slides. They allow to switch even with very low forces and large flow reliably. In addition, ball valves are known which are adjusted by means of a lever and release or close channels in the ball as a function of the angle of rotation of the ball in cooperation with the housing. As poppet valves, linear-acting valves are known which contain limited sealing balls, they are suitable for high pressures and for small flow rates.
Wenn ein Ventil mit geringem Druck betrieben werden soll, sind Wegeventile mit zylindrischen Schiebern dennoch aufwendig herzustellen, weil sowohl der Schieber als auch die Ventilbohrung hohe Formgenauigkeit aufweisen müssen. Dagegen sind Kugeln mit hoher Genauigkeit preiswert herzustellen und das gilt auch für Bohrungen, die lediglich einen hochgenauen Durchmesser aufweisen müssen, aber keine hohen Anforderungen an die Zylinderform erfüllen müssen.When a valve is to be operated with low pressure, directional valves with cylindrical slides are still expensive to produce, because both the slide and the valve bore must have high dimensional accuracy. In contrast, balls with high accuracy are inexpensive to manufacture and that also applies to holes that only need to have a high-precision diameter, but do not have to meet high demands on the cylindrical shape.
Aufgabe dieser Erfindung ist es, ein Wegeventil zu beschreiben, das wichtige Vorteile eines Schieberventils aufrechterhält, zum Beispiel die einfache Betätigung mit geringen Kräften, aber erheblich kostengünstiger herzustellen ist.The object of this invention is to describe a directional control valve which maintains important advantages of a spool valve, for example the simple operation with low forces, but is considerably less expensive to produce.
Die Aufgabe wird durch die kennzeichnenden Merkmale des ersten Anspruchs gelöst, die Unteransprüche führen die Erfindung weiter, die beiden letzten Unteransprüche beschreiben Verfahren zum Betrieb eines erfindungsgemäßen Ventils.The object is achieved by the characterizing features of the first claim, the subclaims carry on the invention, the last two claims describe methods for operating a valve according to the invention.
Den Aufbau, die Funktionsweise und das Verfahren zum Betrieb des erfindungsgemäßen Wegeventils sind in der Beschreibung der beispielhaften Ausführung sowie den Patentansprüchen geschildert, sie werden hier nicht wiederholt.The structure, the operation and the method for operating the directional control valve according to the invention are described in the description of the exemplary embodiment and the claims, they are not repeated here.
Das erfindungsgemäße Wegeventil zeichnet sich durch einen sicheren Betrieb aus. Es ist kostengünstig herzustellen und lässt sich mit geringen Stellkräften betätigen, solange die Drücke nicht hoch sind. Die günstigen Herstellkosten ergeben sich aus der Verfügbarkeit hochgenauer Kugeln aus der Massenfertigung von Kugellagern und aus den erheblich geringeren Anforderungen an die Zylinderform der Ventilbohrung.The directional control valve according to the invention is characterized by a safe operation. It is inexpensive to manufacture and can be operated with low actuating forces as long as the pressures are not high. The low production costs result from the availability of high-precision balls from the mass production of ball bearings and from the significantly lower demands on the cylinder shape of the valve bore.
Anwendung findet das beschriebene Ventil in Abgasreinigungsanlagen für Verbrennungsmotoren. Dort ist es in einigen Systemen erforderlich, die Wirkrichtung von Dosier- oder Förderpumpen umzuschalten. Solche Pumpen fördern Kraftstoff oder wasserhaltige Zusatzstoffe in den Abgasstrang des Motors und werden vorteilhafterweise als Hubkolbenpumpen ausgeführt.The valve described is used in emission control systems for internal combustion engines. There it is necessary in some systems to switch the effective direction of dosing or feed pumps. Such pumps promote fuel or water-containing additives in the exhaust line of the engine and are advantageously designed as reciprocating pumps.
