ABSTRACT:
A breather device of an engine comprises a pressure chamber communicating with the crank chamber of the engine, an oil sump chamber communicating via a pressure-responsive valve with said pressure chamber, a breather chamber communicating via an oil holding wall with said oil sump chamber and communicating also with the engine air intake system, and oil return passage means having a downstream end submerged in oil in an oil pan, said oil sump chamber being communicative with the oil return passage means. Positive pressure in the crank chamber causes blow-bye gas wherein to flow via the pressure chamber and the pressure-responsive valve into the oil sump chamber, then to detour over the oil holding wall into the breather chamber, and then to flow into the air intake system, while lubricating oil contained in the blow-bye gas in the crank chamber is separated from the blow-bye gas in the pressure chamber, the pressure-responsive valve, and the oil sump chamber, and oil retained in the oil sump chamber is circulated back through the oil return passage means to the oil pan.
