Abstract (en)

[origin: EP1067276A1] An internal-combustion engine (1) provided with a purifying device (7) having an inlet communicating with the interior of the crankcase (4) of the engine (1) so as to receive the breather gases containing oil in suspension, an outlet (9) for the purified breather gases, a filter element (22) interposed between the inlet and the outlet, an oil- collecting chamber (28) communicating with the interior of the crankcase (4) via a drain valve (33) designed to allow the passage of the oil accumulated in the chamber (28) towards the crankcase (4) but to prevent the reflux of gases in the opposite direction; said valve (33) comprises a sealing element (38) sensitive to fluctuations in pressure in the crankcase (4) during operation of the engine (1) and designed to allow a quantity of oil to escape when the pressure in the crankcase (4) falls below a predetermined threshold value. <IMAGE>
