Abstract
This cyclone device performs diphasic gas-oil separation to remove oil from the recirculated crank cases of an internal combustion engine. Mounted such that it can move vertically inside the cyclone is a body (7) exhibiting symmetry of revolution, particularly one of cylindro-conical overall shape. The body (7) delimits, with the walls of the cylindrical collecting zone (2) and/or of the conical zone (3) for recuperating the liquid oil, an annular gap (13) such that the passage cross section can vary according to the self-adjusting heightwise position of the body (7), as a function of the gas flow rate. The speed of the gases thus remains constant for variable gas flow rates.
