Abstract
Die Erfindung betrifft ein Elektromagnetventil, mit einem in einem Ventilgehäuse (10) axial beweglich angeordneten Ventilschließglied (2), das einen Ventildurchlass (4) in einem Ventilsitzkörper (1) elektromagnetisch zu öffnen vermag, wobei der Ventilsitzkörper (1) an seiner dem Ventilschließglied (2) zugewandten Stirnfläche die Kontur eines Kegelstumpfs aufweist, der mit mehreren Nuten (3) versehen ist, die sich in Radialrichtung abschnittsweise vom Außendurchmesser (DA) zu dem den Ventildurchlass (4) begrenzenden Innendurchmesser (DI) des Ventilsitzkörper (1) erstrecken. The invention relates to a solenoid valve having a valve closure member (2) arranged axially movably in a valve housing (10) and capable of electromagnetically opening a valve passage (4) in a valve seat body (1), the valve seat body (1) being provided with the valve closure member (1). 2) facing the contour of a truncated cone, which is provided with a plurality of grooves (3) extending in the radial direction in sections from the outer diameter (D A ) to the valve passage (4) limiting the inner diameter (D I ) of the valve seat body (1) ,
Description
Die Erfindung betrifft ein Elektromagnetventil, insbesondere für ein Kraftfahrzeug-Luftfedersystem, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a solenoid valve, in particular for a motor vehicle air spring system, according to the preamble of
Aus der nicht vorveröffentlichten Patentanmeldung
Das Elektromagnetventil hat jedoch den Nachteil, dass bei einer radialen Verformung des Ventilschließgliedes eine unerwünschte Vergrößerung des Dichtdurchmessers am Ventilsitzkörper hervorgerufen werden kann, womit sich durch einen veränderten Differenzdruck des vorzugsweise pneumatisch beaufschlagten Ventilsitzkörpers sich die Schaltcharakteristik des Elektromagnetventils verändern kann.However, the solenoid valve has the disadvantage that in a radial deformation of the valve closing member, an undesirable increase in the sealing diameter can be caused on the valve seat body, which can change the switching characteristic of the solenoid valve by changing the differential pressure of the preferably pneumatically actuated valve seat body.
Daher ist es nunmehr die Aufgabe der vorliegenden Erfindung, ein Elektromagnetventil der angegebenen Art mit möglichst einfachen, funktionsgerechten Mitteln kostengünstig auszuführen und derart baulich zu verbessern, dass ohne signifikante Veränderung des Differenzdrucks das Elektromagnetventil mit einer möglichst geringen Magnetkraft geöffnet werden kann.Therefore, it is now the object of the present invention to inexpensively perform a solenoid valve of the specified type with the simplest possible, functionally appropriate means and to improve structurally such that without significant change in the differential pressure, the solenoid valve can be opened with the lowest possible magnetic force.
Diese Aufgabe wird erfindungsgemäß für das Elektromagnetventil der angegebenen Art durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved according to the invention for the solenoid valve of the type indicated by the features of
