Crankcase vent with centrifuge for oil sepn. - has peripheral centrifugal inlets for blow-by gases

摘要

In i.c. engine crankcase venting, in which blow-by gases are fed through a centrifuge for oil sepn., the novelty is that the blow-by gases enter the centrifuge at the periphery and exit centrally. The centrifuge has one or more channels (5a, b), each of which extends radially to the rotational axis (4) of a rotating element of the engine. The channels are arranged opposite one another in pairs in a gear wheel/sprocket wheel (3) within the crankcase (1), the gear wheel opt. being in the form of a one-piece sintered part with the channels (5a, b). ADVANTAGE - Lubricating oil droplets cannot enter the inlets of the high speed centrifuge so that oil sepn. efficiency is optimised.
