Title
(DE) KURBELGEHÄUSE-ENTLÜFTUNGSVENTIL
(EN) CRANKCASE VENTING VALVE
(FR) SOUPAPE DE VENTILATION DU CARTER
Abstract
(DE)
Es wird ein Kurbelgehäuse-Entlüftungsventil für eine Brennkraftmaschine vorgeschlagen. Dieses weist eine Öffnung für die zugeführten Kurbelgehäusegase auf sowie einen Auslaß für die gereinigten Gase. Außerdem ist ein Ein- und ein Auslaß für Flüssigkeit vorgesehen. Das Kurbelgehäuse-Entlüftungsventil zeichnet sich dadurch aus, daß ein Flüssigkeitsreservoir (16) gebildet ist sowie eine Leitvorrichtung (17, 18) zum Führen der zugeführten Kurbelgehäusegase durch das Flüssigkeitsreservoir (16).
(EN)
The invention concerns a crankcase venting valve for an internal combustion engine, the valve comprising an aperture for the delivered crankcase gases and an outlet for the purified gases. Also provided are an inlet and an outlet for fluid. The crankcase venting valve is characterized in that a fluid reservoir (16) is formed as is a guide device (17, 18) for guiding the delivered crankcase gases through the fluid reservoir (16).
(FR)
L'invention concerne une soupape de ventilation du carter d'un moteur à combustion interne, qui présente une ouverture pour les gaz du carter acheminés, ainsi qu'une sortie pour les gaz épurés. En outre, il est prévu un orifice d'entrée et un orifice de sortie pour liquide. Cette soupape de ventilation du carter se caractérise en ce qu'il est prévu un réservoir de liquide (16), ainsi qu'un dispositif de guidage (17, 18) pour guider à travers le réservoir de liquide (16) les gaz du carter acheminés.
