Abstract

Verfahren und Vorrichtung zur Verringerung des Motor­ ölverbrauches von oszillierenden Verbrennungskraftmaschi­ nen, womit aus den Entlüftungsgasen des Kurbelgehäuses dieser Maschinen die Ölbestandteile vor dem Eintritt dieser Gase in den Ansaugkanal dieser Maschinen abgeschieden und in das Kurbelgehäuse zurückgeführt werden. Dabei weist die Vorrichtung einen in die Entlüftungsleitung zwi­ schen Kurbelgehäuse und Ansaugkanal einfügbaren Abscheidebehälter für Öl mit einem Absauggerät zum Rück­ fördern des abgeschiedenen Öles in das Kurbelgehaüse auf. Method and device for reducing the engine oil consumption of oscillating internal combustion engines with what from the ventilation gases of the crankcase of these machines the oil components before the entry of these Gases are deposited in the intake duct of these machines and be returned to the crankcase. Here the device has one in the vent line between the crankcase and intake duct Separation tank for oil with a suction device to the rear convey the separated oil into the crankcase.
