Abstract
Hydraulikaggregat für eine hydraulische Steuer- oder Regelvorrichtung, insbesondere für eine Bremsdruckregelvorrichtung in Antiblockierregelsystemen oder Antriebsschlupfregelsystemen für Kraftfahrzeuge, mit einem mindestens ein elektromagnetisch schaltbares Ventil aufnehmenden Ventilaufnahmekörper, der hydraulische Komponenten, wie Druckspeicher, Rückschlagventil, Drossel usw. umfaßt, dadurch gekennzeichnet, daß der Ventilaufnahmekörper (1) einen gasdurchlässigen, jedoch flüssigkeits- und festkörperpartikelundurchlässigen Wandabschnitt (2) aufweist, der eine druckausgeglichene Kammer (3) des Druckspeichers (4) begrenzt.hydraulic power unit for one hydraulic control or regulating device, in particular for a brake pressure regulating device in antilock braking systems or traction control systems for motor vehicles, with a receiving at least one electromagnetically switchable valve Valve accommodating member, the hydraulic components, such as pressure accumulator, check valve, Throttle, etc., characterized in that the Valve receiving body (1) a gas-permeable, however liquid and solid particle-impermeable wall portion (2) having a pressure balanced chamber (3) of the pressure accumulator (4) limited.
Description
Die Erfindung betrifft ein Hydraulikaggregat für eine hydraulische Steuer- oder Regelvorrichtung nach dem Oberbegriff des Anspruchs 1.The The invention relates to a hydraulic unit for a hydraulic control or regulating device according to the preamble of claim 1.
Aus
der
Daher ist es die Aufgabe der Erfindung, ein Hydraulikaggregat zu schaffen, dessen Druckspeicher korrosionsgeschützt, kosten- und gewichtsreduziert und unabhängig von den Anordnungserfordernissen des Gesamtaggregates in Ventilaufnahmekörper integriert werden kann, ohne daß die dem Druckspeicherraum abgewandte Kammer flüssigkeits- und differenzdruckbeaufschlagt wird.Therefore It is the object of the invention to provide a hydraulic power unit, its pressure accumulator protected against corrosion, cost and weight reduced and independent integrated by the arrangement requirements of the entire aggregate in valve body can be without the the chamber facing away from the pressure accumulator chamber liquid and differential pressure becomes.
Diese Aufgabe wird erfindungsgemäß durch die den Patentanspruch 1 kennzeichnenden Merkmale gelöst. Die Erfindung basiert somit auf dem Gedanken, den Ventilaufnahmekörper mit einem gasdurchlässigen, jedoch flüssigkeits- und festkörperpartikelundurchlässigen Wandabschnitt zu versehen, der von einer druckausgeglichenen Kammer des Druckspeichers begrenzt wird.These The object is achieved by the the patent claim 1 characterizing features solved. The Invention is thus based on the idea, the valve body with a gas permeable, however liquid and solid particle-impermeable wall portion to be provided by a pressure balanced chamber of the pressure accumulator is limited.
Eine weitere Präzisierung des Erfindungsgedankens geht aus den Merkmalen der Ansprüche 2 und 3 hervor, wonach der gasdurchlässige Wandabschnitt eine in einer Seitenfläche des Ventilaufnahmekörpers befindlichen Öffnung flüssigkeitsundurchlässig verschließt und wobei die Öffnung den im Ventilaufnahmekörper eingesetzten Druckspeicher in der waagerechten Montageebene des Hydraulikaggregates aufnimmt.A further clarification of the inventive concept is based on the features of claims 2 and 3, after which the gas-permeable wall section one in a side surface of the valve receiving body located opening impermeable to liquids and closes the opening the in the valve receiving body used pressure accumulator in the horizontal mounting plane of the hydraulic unit receives.
Eine besonders zuverlässige, leichtbauenede und kostengünstige Lösung des bestehenden Problems, wird durch die Merkmale der Ansprüche 4 und 5 beschrieben, wonach der Wandabschnitt aus einer atmungsaktiven Membran gebildet ist, oder aus einem hydrophobierten Material mit geringer Formänderung, vorzugsweise Kunstfasermaterial mit hoher Gewebedichte, besteht.A particularly reliable, lightweight and cost-effective solution the existing problem is solved by the features of claims 4 and 5, after which the wall section is made of a breathable material Membrane is formed, or made of a hydrophobic material with slight change in shape, preferably synthetic fiber material with high fabric density.
Den gasdurchlässigen Wandabschnitt, gemäß Anspruch 6, aus einem semipermeablen Gewebe herzustellen, stellt eine weitere zweckmäßige Ausgestaltung des Erfindungsgedankens dar, der sowohl durch die Verwendung einer Membran oder durch das hydrophobierte Material hoher Steifigkeit zum Tragen kommen.The gas permeable Wall section, according to claim 6, made from a semipermeable tissue, represents another expedient embodiment of the inventive idea, both by the use of a Membrane or by the hydrophobic material of high stiffness for Wear come.
Die Merkmale der Ansprüche 7 bis 9 beschreiben eine zweckmäßige Konstruktionsform und mehrere Befestigungsarten für die gasdurchlässige Wand, wonach der Wandabschnitt entlang seinem Umfang ein mit einem Stützkörper eingefaßtes Gewebematerial aufweist, das mittels Reibschluß oder Formschluß flüssigkeitsdicht in der Öffnung des Druckspeichers gehalten wird.The Features of the claims Figs. 7 to 9 describe a convenient construction and several types of fastening for the gas-permeable wall, after which the wall portion along its periphery a tissue material rimmed with a support body has, the liquid-tight by friction or positive engagement in the opening the accumulator is held.
Die Merkmale und Vorteile der Erfindung werden nachfolgend anhand einer Zeichnung näher dargestellt und erläutert.The Features and advantages of the invention will be described below with reference to a Drawing shown in more detail and explained.
