摘要

Device for removing oil from blowby gases from combustion engines comprises cyclones (2, 3, 4) equipped with an automatic valve (15) which covers gas outlet openings (10b, 10c, 10d) of an immersion pipe (10). The closing element of the valve is placed under a defined pre-tension and is moved into an opening and closing position depending on the pressure difference between the pressure on its lower side and upper side. The closing element release the gas outlet openings via an opening gap and is connected to each cyclone. Preferred Features: The immersion pipes of all the cyclones are equipped with a valve and at least one cyclone has a closing element. The closing elements of the valves of neighboring cyclones are pre- tensioned.
