Abstract
Die Erfindung betrifft ein Elektromagnetventil, mit einem in einem Ventilgehäuse (1) axial beweglich angeordneten Ventilschließglied (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 Ventilschließglieds (4) vorgesehenen Magnetanker (7) und einem Federelement (2), das in einer Durchgangsbohrung (11) des hülsenförmigen Ventilgehäuse (1) derart angeordnet ist, dass der Ventilschließglied (4) in der elektromagnetisch nicht betätigten Grundstellung des Magnetankers (7) in einer vom Ventilsitz (8) abgehobenen Stellung verharrt, wobei zur Abbremsung des Ventilschließgliedes (4) ein zwischen dem Ventilsitz (8) und dem Magnetanker (7) die Bewegung des Ventilschließgliedes (4) verzögernder Tauchkolben (3) angeordnet ist, der mit Radialspiel (S) innerhalb einer Fluidkammer (6) des Ventilgehäuses (1) axial beweglich aufgenommen ist.The invention relates to an electromagnetic valve with a valve closing element (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 the electromagnetic actuation of the valve closing member (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 closing member (4) does not electromagnetically actuated basic position of the magnet armature (7) remains in a position raised from the valve seat (8), with a plunger (3) between the valve seat (8) and the magnet armature (7) delaying the movement of the valve closing element (4) to brake the valve closing element (4) ) is arranged, which is axially movably received with radial play (S) within a fluid chamber (6) of the valve housing (1).
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 Ventilschließglieds auf den Ventilsitz ein unerwünschtes Schaltgeräusch entsteht.However, the construction has the disadvantage that an undesirable switching noise is generated when the valve closing element hits the valve seat.
Daher ist es nunmehr die Aufgabe der vorliegenden Erfindung, ein Elektromagnetventil der eingangs genannten Art zu schaffen, dass den vorgenannten Nachteil nicht aufweist. Ferner soll die Minderung des Schaltgeräuschs nicht nur in der elektromagnetisch initiierten Schließrichtung des Elektromagnetventils wirksam sein, sondern auch beim Ausschalten des Erregerstroms ein geräuschloses Zurückschalten des Elektromagnetventils ermöglichen.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. Furthermore, the reduction of the switching noise should not only be effective in the electromagnetically initiated closing direction of the solenoid valve, but also enable the solenoid valve to switch back noiselessly when the excitation current is switched off.
Diese Aufgabe wird für ein Elektromagnetventil der angegebenen Art erfindungsgemäß durch die den Patentanspruch 1 kennzeichnenden Merkmale gelöst.This object is achieved according to the invention for a solenoid valve of the specified type by the features characterizing
Weitere Merkmale und Vorteile der Erfindung werden im Folgenden anhand der Beschreibung mehrerer Ausführungsbeispiele anhand von Zeichnungen erläutert.Further features and advantages of the invention are explained below with reference to the description of several exemplary embodiments with reference to drawings.
