Abstract
Die Erfindung betrifft eine Ventilanordnung, bestehend aus einem Magnetventil (13) und einem hydraulisch beaufschlagbaren Rückschlagventil (12), das in einer Integralbauweise mit dem Magnetventil (13) angeordnet ist, wobei zur sicheren mechanischen Trennung des Rückschlagventils (12) vom Magnetventil (13) während der elektromagnetischen Aktivierung der Ventilanordnung eine Druckfeder (8) wirksam ist.The invention relates to a valve arrangement, comprising a solenoid valve (13) and a hydraulically loadable check valve (12), which is arranged in an integral construction with the solenoid valve (13), wherein for safe mechanical separation of the check valve (12) from the solenoid valve (13). during the electromagnetic activation of the valve assembly, a compression spring (8) is effective.
Description
Die Erfindung betrifft eine Ventilanordnung, die an einen durch einen Hauptbremszylinder hydraulisch beaufschlagbaren Simulator eines elektrohydraulisches Bremsdruckregelaggregat angeschlossen ist, das in einer Kraftfahrzeugbremsanlage eingesetzt ist, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a valve arrangement which is connected to a hydraulically acted upon by a master cylinder simulator of an electro-hydraulic brake pressure control unit, which is used in a motor vehicle brake system, according to the preamble of
Aus
Nunmehr ist es die Aufgabe der vorliegenden Erfindung, eine Ventilanordnung der angegebenen Art mit möglichst einfachen, kostengünstigen und funktionsgerechten Mittel weiter zu entwickeln. Hierbei soll während einer elektromagnetischen Erregung des Magnetankers darauf geachtet werden, dass auch bei einem hydraulischen Durchfluss unter geringem Druck das Rückschlagventil sicher an seinem großen Ventilsitzquerschnitt verharrt, um ausschließlich über den kleineren Ventilsitzquerschnitt einen gedrosselter Durchfluss innerhalb der Ventilanordnung zuzulassen. Now, it is the object of the present invention to further develop a valve arrangement of the specified type with as simple, inexpensive and functional means. Care should be taken during an electromagnetic excitation of the magnet armature that even with a hydraulic flow at low pressure, the check valve reliably remains at its large valve seat cross-section to allow only on the smaller valve seat cross-section throttled flow within the valve assembly.
Diese Aufgabe wird erfindungsgemäß für eine Ventilanordnung der angegebenen Art mit den Merkmalen des Patentanspruchs 1 gelöst. This object is achieved according to the invention for a valve arrangement of the specified type with the features of
