Abstract
Die Erfindung betrifft ein Elektromagnetventil, mit einem in einem Ventilgehäuse axial beweglich angeordneten Ventilstößel (3), der einen Ventildurchlass in einem Ventilsitz (10) zu öffnen oder zu verschließen vermag, der zwischen zwei Druckanschlüssen (A, B) des Ventilgehäuses angeordnet ist, sowie mit einem zur Betätigung des Ventilstößels (3) vorgesehenen Magnetanker (2), mit der Besonderheit, dass der Ventilsitz (10) in einem Plunger (7) angeordnet ist, der zur Ausübung einer Rückschlagventilfunktion axial beweglich im Ventilgehäuse aufgenommen ist.The invention relates to an electromagnetic valve with a valve tappet (3) which is arranged in a valve housing so that it can move axially and which is able to open or close a valve passage in a valve seat (10) which is arranged between two pressure connections (A, B) of the valve housing with a magnet armature (2) provided for actuating the valve tappet (3), with the special feature that the valve seat (10) is arranged in a plunger (7) which is accommodated in the valve housing so that it can move axially in order to exercise a non-return valve function.
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
Der Durchfluss des vorgestellten Elektromagnetventils wird durch den Öffnungsquerschnitt innerhalb des Ventilsitzes bestimmt, sodass sich infolge baulicher Grenzen Drosseleffekte einstellen können, die sich im Einsatz des Elektromagnetventils in einer elektrohydraulischen Bremsanlage nachteilig auswirken können. Insbesondere erfordert die unmittelbare Anordnung eines derartigen Elektromagnetventils zwischen einem als Linearaktuator ausgeführten Druckerzeuger und einer Radbremse zur Realisierung großer Druckaufbaugradienten einen möglichst drosselfreie Durchströmung des Elektromagnetventils.The flow of the presented electromagnetic valve is determined by the opening cross-section within the valve seat, so that throttling effects can occur due to structural limitations, which can have a disadvantageous effect when using the electromagnetic valve in an electrohydraulic brake system. In particular, the direct arrangement of such a solenoid valve between a pressure generator designed as a linear actuator and a wheel brake to realize large pressure build-up gradients requires a flow through the solenoid valve that is as throttle-free as possible.
Daher ist es die Aufgabe der vorliegenden Erfindung, ein Elektromagnetventil der eingangs genannten Art hinsichtlich seiner Funktion zu optimieren und möglichst kompakt zu gestalten.Therefore, it is the object of the present invention to optimize an electromagnetic valve of the type mentioned in terms of its function and to make it as compact as possible.
Diese Aufgabe wird für ein Elektromagnetventil der angegebenen Art erfindungsgemäß durch die den Patentanspruch 1 kennzeichnenden Merkmale gelöst.According to the invention, this object is achieved for an electromagnetic valve of the type specified by the features characterizing
