Abstract
Description
Die Erfindung betrifft ein Druckregelventil für Kurbelgehäuseentlüftung eines Verbrennungsmotors nach dem Oberbegriff von Anspruch 1.The The invention relates to a pressure control valve for crankcase ventilation an internal combustion engine according to the preamble of claim 1.
Ein übliches
Druckregelventil für Kurbelgehäuseentlüftung
beispielsweise gemäß
Ein sehr aufwendiger Versuch, bei einem Druckregelventil einen konstanten Unterdruck auf der druckgeregelten Seite unabhängig von dem Unterdruck auf der Saugseite zu erreichen, ist beispielsweise eine elektronische Regelung des Ventils in Abhängigkeit des gemessenen Kurbelgehäusedrucks.One very elaborate attempt at a pressure control valve a constant Vacuum on the pressure-controlled side regardless of to reach the negative pressure on the suction side, for example an electronic control of the valve in dependence the measured crankcase pressure.
Es
sind verschiedene Versuche unternommen worden, um zumindest bei
sehr hohem Unterdruck auf der Saugseite ein zuverlässiges Öffnen
des Ventils sicherzustellen.
Gleiches
gilt für das Druckregelventil gemäß
Die Aufgabe der Erfindung besteht darin, ein Druckregelventil bereitzustellen, das mit vergleichsweise einfachen Mitteln im Regelbereich einen vom Saugdruck im Wesentlichen unabhängigen Unterdruck auf der unterdruckgeregelten Seite einstellt.The The object of the invention is to provide a pressure regulating valve, that with comparatively simple means in the control area from the suction pressure substantially independent negative pressure the vacuum-regulated side sets.
Die Erfindung löst diese Aufgabe mit den Mitteln von Anspruch 1. Aufgrund der von der Strömungskammer entkoppelten Steuerdruckkammer, die nur mit dem Druck auf der unterdruckgeregelten Seite beaufschlagt ist, kann das Ventilglied gezielt unabhängig vom Druck im Ansaugtrakt angesteuert werden. Die im Wesentlichen druckkompensierte Ausführung des Ventilglieds in Bezug auf den Druck in der Strömungskammer stellt sicher, dass Schwankungen des saugseitigen Drucks das Ventilglied im Wesentlichen unbeeinflusst lassen. Aufgrund der Unabhängigkeit vom Saugdruck ist das Druckregelventil universell einsetzbar und kann an einer beliebigen Position in der Kurbelgehäuseentlüftung, insbesondere vor oder hinter etwaigen Ölabscheidern, angeordnet werden.The invention solves this problem by the means of claim 1. Due to the decoupled from the flow chamber control pressure chamber, which is acted upon only by the pressure on the vacuum-controlled side, the valve member can be selectively controlled independently of the pressure in the intake. The substantially pressure-compensated design of the valve member with respect to the pressure in the flow chamber ensures that fluctuations in the suction-side pressure, the valve member in Leave essentially unaffected. Due to the independence of the suction pressure control valve is universally applicable and can be arranged at any position in the crankcase ventilation, especially in front of or behind any oil separators.
Bevorzugt ist eine im Wesentlichen vollständige Druckkompensation. Umfasst ist aber auch eine unvollständige Druckkompensation, sofern der Einfluss von Schwankungen des saugseitigen Drucks auf das Ventilglied tolerierbar klein ist.Prefers is a substantially complete pressure compensation. But includes also an incomplete pressure compensation, provided that the influence of variations in the suction pressure on the valve member is tolerably small.
Druckkompensation kann insbesondere dadurch erreicht werden, dass die dem Strömungskammerdruck ausgesetzten entgegengesetzten Wirkflächen des Ventilglieds im Wesentlichen gleich groß ausgebildet sind.pressure compensation can be achieved in particular by the flow chamber pressure exposed opposite active surfaces of the valve member are formed substantially the same size.
Vorzugsweise ist eine gehäusefeste Trennwand zwischen der Strömungskammer von der Steuerdruckkammer vorgesehen, um eine Beeinflussung des Drucks in der Steuerdruckkammer von dem Strömungskammerdruck und damit dem Saugdruck zu unterbinden.Preferably is a housing-fixed partition wall between the flow chamber provided by the control pressure chamber, in order to influence the Pressure in the control pressure chamber of the flow chamber pressure and thus to prevent the suction pressure.
