Abstract:
A lubricating oil filler line of an internal combustion engine (1) with an oil mist separator (5) for crankcase ventilation, out of which the oil separated from the oil mist separator (5) flows as return oil under the effect of gravity, and in whicha return-oil line (8) starting from the oil mist separator (5) and leading into the interior of the lubricating oil filler line (1) is provided for the return oil,that end of the return-oil line (8) which is remote from the oil mist separator (5) leads into the bottom region of an overflow vessel (9) intended for receiving and transferring the return oil,a gas pressure prevails at the overflow orifice of the overflow vessel (9), said gas pressure corresponding to that under which the oil mist arriving at the oil separator (5) is,the lubricating oil filler line (1) is designed as an independent element which has, at one end, a flange (2) for a connection to an internal combustion engine and, at its other end, a closeable filler orifice, defined by the featuresthe oil mist separator (5) is located outside the lubricating oil filler line (1) and is connected to the latter via a separating flange of a flanged connection (4),for crankcase ventilation, a line (6) leads out of the interior of the lubricating oil filler line (1) into the oil mist separator (5),the lines (6) and (8) run through the flanged connection (4) and are separate.
