Abstract
A breather device for an engine comprises a gas-liquid separation chamber communicating with the crankcase chamber through the one-way valve, a breather passage opening the gas-liquid separation chamber into an air cleaner, first and second oil suction holes arranged below and above an inner end of the breather passage opening to the gas-liquid separation chamber, and an oil passage communicating the first and second oil suction holes to an oil reservoir chamber having a pressure lower than that of the gas-liquid separation chamber. This construction enables the oil separated from the blow-by gas and liquefied in the gas-liquid separation chamber to be returned quickly to the oil reservoir chamber through the first or second oil suction holes, irrespective of whether the engine is in an normal upright position or an inverted position.
