Abstract
Description
Die Erfindung betrifft ein Hydraulikaggregat für eine Kraftfahrzeugbremsanlage nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a hydraulic unit for a motor vehicle brake system according to the preamble of patent claim 1.
Ein Hydraulikaggregat für eine Kraftfahrzeugbremsanlage der angegebenen Art ist aus
In einen für die Bevorratung des Druckmittels im Niederdruckspeicher vorgesehenen Speicherraum ist ein translatorisch bewegter Speicherkolben flüssigkeitsdicht aufgenommen, der in der Regel einen Dichtring aufweist, der einem gewissen Verschleiß unterworfen ist, sodass Verschleißpartikel in den Pumpensaugpfad eingespült werden können, die nicht nur zur Pumpe gelangen, sondern auch zu einer Kontamination des elektrischen Umschaltventils führen und die im Falle einer Rückströmung des Druckmittels auch die Auslassventile verunreinigen.In a space provided for the storage of the pressure medium in the low-pressure accumulator storage space, a translationally moving accumulator piston is liquid-tight, which usually has a sealing ring which is subjected to a certain wear, so that wear particles can be flushed into the Pumpensaugpfad not only reach the pump but also lead to contamination of the electrical switching valve and contaminate in the case of a backflow of the pressure medium and the exhaust valves.
Die Aufgabe der Erfindung ist es nunmehr, ein Hydraulikaggregat der angegebenen Art dahingehend zu verbessern, dass mit möglichst geringem konstruktiven als auch funktionellen Aufwand eine Kontamination des Pumpensaugpfades sowohl in Richtung des elektrischen Umschaltventils als auch in Richtung der Auslassventile sicher verhindert wird falls Druckmittel aus dem Niederdruckspeicher zu den Auslassventilen rückströmen sollte.The object of the invention is therefore to improve a hydraulic unit of the specified type to the effect that with the least possible constructive and functional effort contamination of the pump suction both in the direction of the electric switching valve and in the direction of the exhaust valves is reliably prevented if pressure medium from the low-pressure accumulator should flow back to the exhaust valves.
Diese Aufgabe wird erfindungsgemäß für ein Hydraulikaggregat der genannten Art durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved for a hydraulic unit of the type mentioned by the features of claim 1.
Weitere Merkmale der Erfindung sind den einzelnen Patentansprüchen als auch aus der Beschreibung zweier Ausführungsbeispiele zu entnehmen.Further features of the invention can be taken from the individual claims as well as from the description of two embodiments.
