Abstract
Die Erfindung betrifft ein Elektromagnetventil, mit einem in einem Ventilgehäuse (1) axial beweglich angeordneten Ventilstößel (4), der im Ventilgehäuse (1) einen Ventildurchlass (9) zu öffnen oder zu verschließen vermag, welcher in einem Ventilsitz (8) ausgebildet ist, sowie mit einem zur elektromagnetischen Betätigung des Ventilstößels (4) vorgesehenen Magnetanker (7) und einem Federelement (2), das in einer Durchgangsbohrung (11) des hülsenförmigen Ventilgehäuse (1) derart angeordnet ist, dass der Ventilstößel (4) in der elektromagnetisch nicht betätigten Grundstellung des Magnetankers (7), in einer vom Ventilsitz (8) abgehobenen Stellung verharrt, wobei zur Abbremsung des Magnetankers (7) während des Schließhubs des Ventilstößels (4) in der Durchgangsbohrung (11) des Ventilgehäuses (1) ein elastisches Dämpfungselement (3) eingesetzt ist, das mittelbar über ein vom Magnetanker (7) beaufschlagbares Druckstück (5) komprimierbar ist.The invention relates to an electromagnetic valve with a valve tappet (4) which is arranged axially movably in a valve housing (1) and is able to open or close a valve passage (9) in the valve housing (1) which is formed in a valve seat (8), as well as with a magnet armature (7) provided for electromagnetic actuation of the valve tappet (4) and a spring element (2) which is arranged in a through hole (11) of the sleeve-shaped valve housing (1) in such a way that the valve tappet (4) is not electromagnetically actuated basic position of the magnet armature (7), remains in a position lifted from the valve seat (8), an elastic damping element (1) in the through-hole (11) of the valve housing (1) to brake the magnet armature (7) during the closing stroke of the valve stem (4) 3) is used, which can be compressed indirectly via a pressure piece (5) that can be acted upon by the magnet armature (7).
Description
Die Erfindung betrifft ein Elektromagnetventil, insbesondere für schlupfgeregelte Kraftfahrzeugbremsanlagen, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an electromagnetic valve, in particular for slip-controlled motor vehicle brake systems, according to the preamble of
Aus der
Die Konstruktion hat jedoch den Nachteil, dass mit dem Auftreffen des Ventilstößels auf den Ventilsitz ein unerwünschtes Schaltgeräusch entsteht.However, the construction has the disadvantage that when the valve tappet strikes the valve seat, an undesirable switching noise occurs.
Daher ist es nunmehr die Aufgabe der vorliegenden Erfindung, ein Elektromagnetventil der eingangs genannten Art zu schaffen, dass den vorgenannten Nachteil nicht aufweist.It is therefore now the object of the present invention to create an electromagnetic valve of the type mentioned at the beginning that does not have the aforementioned disadvantage.
Diese Aufgabe wird für ein Elektromagnetventil der angegebenen Art erfindungsgemäß durch die den Patentanspruch 1 kennzeichnenden Merkmale gelöst, indem der Ventilstößel vor dem Auftreffen auf den Ventilsitz mittels eines geeigneten Dämpfungselements abgebremst wird.This object is achieved according to the invention for an electromagnetic valve of the specified type by the features characterizing
Weitere Merkmale und Vorteile der Erfindung werden im Folgenden anhand der Beschreibung eines Ausführungsbeispiels anhand mehrerer Zeichnungen erläutert.Further features and advantages of the invention are explained below with reference to the description of an exemplary embodiment with reference to several drawings.

-
1 das erfindungsgemäße Elektromagnetventil im Längsschnitt in seiner elektromagnetisch nicht betätigten Grundstellung, in welcher der Ventildurchlass vom Ventilstößel freigegeben ist. -
2 das Elektromagnetventil nach1 in der elektromagnetisch erregten Schaltstellung, in welcher der Magnetanker nach Überbrückung eines Leerhubs ein Druckstück kontaktiert, das auf ein komprimierbares elastisches Dämpfungselement einwirkt, -
3 das Elektromagnetventil in seiner elektromagnetisch geschlossenen Schaltstellung, in welcher der Ventilstößel unter Kompression des Dämpfungselements mit vermindertem Impuls auf den Ventilsitz auftrifft und den Ventildurchlass verschließt.

1 the electromagnetic valve according to the invention in longitudinal section in its electromagnetically non-actuated basic position in which the valve passage is released from the valve tappet. -
2 the solenoid valve after1 in the electromagnetically excited switch position in which the armature contacts a pressure piece after bridging an idle stroke, which acts on a compressible elastic damping element, -
3 the solenoid valve in its electromagnetically closed switching position, in which the valve tappet hits the valve seat with compression of the damping element with reduced momentum and closes the valve passage.
