Abstract
Druckregelventil für den Einbau in eine Entlüftungsleitung an einer Brennkraftmaschine insbesondere zwischen Kurbelgehäuse und Ansaugrohr bzw. Luftfilter, mit einem Ventilgehäuse (11), das aus einem topfförmigen Gehäuseunterteil und einem Gehäusedeckel (13) zusammengesetzt ist, mit einem in das Gehäuseunterteil einmündenden Zuflussstutzen und einem aus dem Gehäuseunterteil ausmündenden Abflussstutzen, dessen zentral innerhalb des Ventilgehäuses (11) angeordnetes Stutzenende als Ventilsitz (21) ausgebildet ist, sowie mit einem an seinem Rand in einer Nut zwischen dem Gehäusedeckel (13) und dem Gehäuseunterteil abgedichtete eingeklemmten Membranventilkörper, der das Ventilgehäuse (11) in eine Ventilkammer (32) und eine über einen Belüftungskanal (16) mit der Atmosphäre verbundene Belüftungskammer unterteilt, wobei die Membran (14) eine dem Ventilsitz (21) am Stutzenende zugewandte Ventilplatte (22) aufweist und mit einer Druckfeder, welche sich an dem Boden des Gehäuseunterteils abstützt und eine Kraft auf die Membran (14) in Richtung des Gehäusedeckels ausübt, wobei zwischen der Ventilplatte der Membran und dem ersten Ventilsitz (17) am Gehäuseunterteil ein Zwischenventil angeordnet ist, welches einen zweiten Ventilsitz aufweist, der der Membran (14) zugewandt ist und mit der Ventilplatte der Membran zusammenwirkt und eine Ventilplatte aufweist, welche dem Ventilsitz (17) des Gehäuseunterteils zugewandt ist und mit diesem zusammenwirkt, wobei das Zwischenventil an der Membran derart angeordnet ist, dass eine axiale Relativbewegung zwischen der Membran und dem Zwischenventil möglich ist, wobei das Zwischenventil eine Einrichtung zur Strömungsumleitung aufweist, welche lösbar oder unlösbar mit der Ventilplatte verbunden ist. Pressure control valve for installation in a vent line on an internal combustion engine, in particular between the crankcase and intake pipe or air filter, comprising a valve housing (11) composed of a cup-shaped housing lower part and a housing cover (13), with an inlet connection opening into the housing lower part and one out The discharge nozzle opening out from the lower part of the housing, the nozzle end of which is arranged centrally within the valve housing (11) as a valve seat (21), and a clamped membrane valve body which is sealed at its edge in a groove between the housing cover (13) and the housing lower part and which holds the valve housing (11 ) in a valve chamber (32) and a via a ventilation duct (16) connected to the atmosphere ventilation chamber, wherein the membrane (14) has a valve seat (21) at the nozzle end facing valve plate (22) and with a compression spring, which at the floor of the housing and supports a force on the membrane (14) in the direction of the housing cover, wherein between the valve plate of the membrane and the first valve seat (17) on the lower housing part an intermediate valve is arranged, which has a second valve seat facing the membrane (14) is and cooperates with the valve plate of the diaphragm and having a valve plate which faces the valve seat (17) of the housing base and cooperates therewith, wherein the intermediate valve is arranged on the membrane such that an axial relative movement between the diaphragm and the intermediate valve is possible wherein the intermediate valve has a device for flow diversion, which is releasably or non-detachably connected to the valve plate.
