Abstract
Description
Die Erfindung betrifft ein Ventil insbesondere für die Kurbelgehäuseentlüftung eines Kraftfahrzeugs nach dem Oberbegriff von Anspruch 1.The The invention relates to a valve, in particular for crankcase ventilation of a motor vehicle according to the preamble of claim 1.
Ein
Ventil in einem Ölabscheider für die Kurbelgehäuseentlüftung
eines Kraftfahrzeugs nach dem Oberbegriff von Anspruch 1 ist in
der
Die Aufgabe der Erfindung besteht darin, ein kompaktes, aus einer relativ geringen Anzahl von Teilen bestehendes und über einen definierten Arbeitsbereich effizient arbeitendes Ventil bereitzustellen.The The object of the invention is a compact, from a relative small number of parts existing and over a defined one Work area to provide efficient working valve.
Die Erfindung löst diese Aufgabe mit den Mitteln von Anspruch 1. Bei einem magnetisch geschalteten Ventil kann der Ventilkörper vorspannungsfrei gehalten sein, weil aufgrund der digitalen Schaltcharakteristik die Federkennlinie nicht zum Tragen kommt und die Rückstellkraft in die Geschlossenstellung anders erreicht werden kann. Erfindungsgemäß kann daher auf die herkömmliche vorspannungserzeugende Feder verzichtet und die Anzahl der Teile somit reduziert werden. Indem der Ventilkörper in der Gasdurchtrittsöffnung selbst geführt ist, kann auf zusätzliche Durchlassöffnungen verzichtet werden, wodurch der Bauraum erheblich reduziert werden kann.The Invention solves this problem by the means of claim 1. With a magnetically switched valve, the valve body be kept free of bias, because due to the digital switching characteristic the spring characteristic does not come into play and the restoring force can be achieved differently in the closed position. According to the invention therefore, on the conventional bias generating spring dispensed with and the number of parts are thus reduced. By doing the valve body in the gas passage opening Self-guided, can access additional ports be omitted, whereby the space can be significantly reduced can.
Vorzugsweise bildet das permanentmagnetische Element ein erstes Anschlagmittel, das die axiale Verschiebung des Ventilkörpers in einer Geschlossenstellung begrenzt. Ein separates Anschlagmittel ist dann nicht erforderlich. Vorzugsweise ist das permanentmagnetische Element als Dichtelement ausgebildet, insbesondere indem es aus einem permanent magnetisierten Elastomermaterial besteht. Diese Maßnahmen tragen jeweils zur Reduzierung der Teile bei, da auf ein separates Dichtelement verzichtet werden kann.Preferably the permanent magnetic element forms a first stop means, the axial displacement of the valve body in one Closed position limited. A separate stop means is then not mandatory. Preferably, the permanent magnetic element designed as a sealing element, in particular by making it a permanent magnetized elastomeric material. These measures each contribute to the reduction of the parts, since on a separate Sealing element can be dispensed with.
In einer bevorzugten Ölabscheidevorrichtung ist zu einem ersten Ölabscheider mit einem erfindungsgemäßen Ventil mindestens ein weiterer Ölabscheider parallel geschaltet, um den Arbeitsbereich der Ölabscheidevorrichtung zu vergrößern. Vorzugsweise kann daher ein weiterer parallel geschalteter Ölabscheider ein bei einem anderen Gasdruck selbsttätig öffnendes Ventil aufweisen. Vorteilhafterweise kann zu demselben Zweck mindestens ein weiterer Ölabscheider ventilfrei ausgebildet sein.In a preferred oil separator is to a first oil separator at least with a valve according to the invention another oil separator connected in parallel to the work area to increase the oil separation device. Preferably, therefore, another parallel-connected oil separator a self-opening at another gas pressure Have valve. Advantageously, at least for the same purpose be another oil separator valve-free.
