Abstract
Description
Die Erfindung betrifft ein Druckregelventil gemäß der Gattung der Patentansprüche. Derartige Ventile finden bevorzugt als Proportionaldruckregelventile in hydraulischen Fahrwerkkomponenten (Federungssysteme, Dämpfungssysteme, Antiwanksysteme) sowie in Ventilen für hydraulische Steuerungen von Fahrzeugverdecken Verwendung.The The invention relates to a pressure control valve according to the preamble of the claims. Such valves find favored as proportional pressure control valves in hydraulic Suspension components (suspension systems, damping systems, anti-roll systems) as well as in valves for hydraulic controls of vehicle concealment use.
Es sind Ventile mit konstanter Dämpfung bekannt, siehe Umdruck zur Vorlesung, Grundlagen der Fluidtechnik, Teil 1: Hydraulik, Univ.-Prof. Dr.-Ing. H. Murrenhoff, 4. neu überarbeitete Auflage 2005, Seiten 240 und 241. Die Dämpfräume befinden sich dabei sowohl auf der Druck- als auch auf der Tankseite. Der Hub des aktiven Ventilelements hat dabei keinen Einfluss auf die Dämpfung.It are valves with constant damping known, see Reprint for the lecture, Fundamentals of fluid technology, Part 1: Hydraulics, Univ.-Prof. Dr.-Ing. H. Murrenhoff, 4th newly revised Edition 2005, pages 240 and 241. The damping chambers are both on the print as also on the tank side. The stroke of the active valve element has no effect on the damping.

Der Erfindung liegt daher die Aufgabe zu Grunde, eine hubvariable Ventildämpfung mit kleinem Bauvolumen, geringem Gewicht und niedrigem Energiebedarf zu schaffen, die betriebspunktabhängige Einflussgrößen weitestgehend ausschließt. Die erfindungsgemäße Ventildämpfung soll darüber hinaus eine hohe Standzeit und eine kostengünstige, prozesssichere Herstellung im jeweiligen Anwendungsfall ermöglichen.Of the Invention is therefore the object of a stroke variable valve damping with small volume, low weight and low energy consumption to create the operating point-dependent influencing variables as far as possible excludes. The valve damping according to the invention is intended about that In addition, a long service life and cost-effective, reliable production enable in each application.
Gemäß der Erfindung wird diese Aufgabe durch die Merkmale des ersten Patentanspruchs gelöst und durch die Merkmale der Unteransprüche vorteilhaft ausgestaltet. Die Nutzung der Druckseite bzw. Hochdruckseite als Dämpfraumperipherie ermöglicht die Trennung der Dämpfung von der nach dem Stand der Technik üblichen, ventilinternen mechanischen Rückführung bei Druckregelventilen. Der Dämpfraum ist also von der Rückführgeometrie (dem Rückführkolben) geometrisch entkoppelt, so dass keinerlei Wechselwirkungen zwischen der Dämpfung und der Rückführung entstehen können. Die Dämpfung ist unabhängig von störenden Einflüssen bei der Druckrückführung, die durch temperaturabhängige, betriebsdruckabhängige und toleranzbedingte Leckagen zustande kommen. Außerdem werden im Dämpfraum Lufteinschlüsse, Kavitationen und Unterdrücke vermieden. Im unteren Betriebsdruckbereich (weniger gedämpft) des Ventils ergibt sich ein schneller Druckaufbau, während im oberen Betriebsdruckbereich eine hohe Druckstabilität (mehr gedämpft) erreicht wird.According to the invention This object is achieved by the features of the first claim solved and advantageously designed by the features of the subclaims. The use of the pressure side or high pressure side as Dämpfraumperipherie allows the separation of the damping from the usual in the art, valve internal mechanical Return at Pressure control valves. The steam room So it's from the feedback geometry (the return piston) geometrically decoupled, so that no interactions between the damping and the return arise can. The damping is independent from disturbing influences in the pressure feedback, the by temperature dependent, operating pressure dependent and Tolerance-related leaks come about. Besides, in the steam room Air pockets, Cavitations and negative pressures avoided. In the lower operating pressure range (less damped) of the Valve results in a rapid pressure build-up, while in the upper operating pressure range a high pressure stability (more subdued) achieved becomes.
