Abstract (en)
An internal-combustion engine (1) provided with a cylinder head (2), a crankcase (4), a plurality of cylinders (3) and breather means (6) for gases which have escaped into the crankcase (4) through the cylinders (3) and containing in suspension particles of lubricating oil; the breather means (6) are provided with a purifying device (8) adapted to separate the particles of oil from the gases and formed by a column-type integrated unit accommodated in a vertical cavity (10) of the crankcase (4) and comprising a hollow outer casing (15) through which the gases to be purified pass, deflector means (16) of generally helical configuration accommodated inside the casing (15) and adapted to divert the gases to be purified along an ascending helical conveying path for separating under centrifugal action the particles of oil from these gases, and a substantially tubular intermediate element (17) accommodated inside the casing (15) downwardly with respect to the deflector means (16), through which the gases to be purified flow internally and upwardly towards the deflector means (16), and which delimits externally with the casing (15) a separate chamber (18) for conveying under gravity the oil particles projected under centrifugal action against an internal surface (19) of the casing (15) adjacent to the deflector means (16). <IMAGE> <IMAGE>
