Abstract[German]
Die Erfindung betrifft ein Rückschlagventil (10), insbesondere zur Steuerung der Strömungsrichtung in einer Druckmittelverbindung eines Hydraulikaggregats einer elektronisch schlupfregelbaren Fahrzeugbremsanlage. Bekannte Rückschlagventile (10) haben ein Ventilgehäuse (12) mit einem Zulauf (16), einem Ablauf (18) und einem dazwischen angeordneten Steuerquerschnitt (20), welcher von einem Schließelement (24) gesteuert ist. Vorgeschlagen wird ein Rückschlagventil (10), bei dem Zulauf (16) und Ablauf (18) einander gegenüberliegen und bei dem das Schließelement (24) im Inneren eines Führungskäfigs (30) im Ventilgehäuse (12) angeordnet ist. Der Führungskäfig (30) verbessert u.a. den Durchflusswiderstand des Rückschlagventils (10).[English]
The invention relates to a check valve (10), in particular for controlling the flow direction in a pressure medium connection of a hydraulic unit of an electronically slip-controllable vehicle brake system. Known check valves (10) have a valve housing (12) with an inlet (16), an outlet (18) and an interposed control cross section (20) which is controlled by a closing element (24). What is proposed is a check valve (10) in which the inlet (16) and the outlet (18) are opposite one another and in which the closing element (24) is located inside a guide cage (30) in the valve housing (12). The guide cage (30) improves, inter alia, the flow resistance of the check valve (10).[French]
L'invention se rapporte à un clapet antiretour (10), en particulier destiné à commander le sens d'écoulement dans un raccord de milieu de pression d'une unité hydraulique d'un système de frein de véhicule à commande électronique antipatinage. Des clapets antiretour connus (10) comportent un corps de clapet (12) pourvu d'une entrée (16), d'une sortie (18) et d'une section transversale de commande interposée (20) qui est commandée par un élément de fermeture (24). Dans le clapet antiretour (10) proposé, l'entrée (16) et la sortie (18) sont opposées l'une à l'autre, et l'élément de fermeture (24) se situe à l'intérieur d'une cage de guidage (30) du corps de clapet (12). La cage de guidage (30) améliore, entre autres, la résistance à l'écoulement du clapet antiretour (10).
