Abstract
Description
Die Erfindung betrifft ein Elektromagnetventil nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a solenoid valve according to the preamble of claim 1
Aus
der
Die vorgestellte Ventilkonstruktion erlaubt keine Magnetkreisproportionalisierung. Das Ventil ist ausschließlich binär schaltbar und somit in seiner Funktion nur beschränkt einsetzbar.The featured valve design does not allow Magnetkreisproportionalisierung. The valve is exclusive binary switchable and thus in its function only limited use.
Zur Vermeidung eines magnetischen Kurzschlusses ist der Magnetkern unterhalb der Magnetspule geöffnet, so dass bei einer ungenügenden Abdichtung des Ankerraums die Magnetspule dem Arbeitsdruck ausgesetzt ist.to Avoidance of a magnetic short circuit is the magnetic core below the solenoid is opened, so that at an insufficient Seal the armature space the solenoid exposed to the working pressure is.
Daher ist es die Aufgabe der vorliegenden Erfindung, ein Elektromagnetventil der angegebenen Art derart zu verbessern, dass die vorgenannten Nachteile vermieden werden.Therefore It is the object of the present invention, a solenoid valve the type specified to improve such that the aforementioned disadvantages be avoided.
Diese Aufgabe wird erfindungsgemäß für ein Elektromagnetventil der angegebenen Art mit den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst.These Task is according to the invention for a solenoid valve the specified type with the characterizing features of claim 1 solved.
Weitere Merkmale, Vorteile und Anwendungsmöglichkeiten der Erfindung gehen im folgenden aus der Beschreibung eines Ausführungsbeispiels anhand zweier Zeichnungen hervor.Further Features, advantages and applications of the invention go in the following from the description of an embodiment with reference to two Drawings forth.
