Abstract

A device for recovering the oil contained in the combustion gas leaving the engine, includes at least one orifice (6) for collecting incoming gas, a flow channel (10) for the incoming gas, at least one gas outlet orifice, a wall (12) closing the flow channel (10), a recovery channel (14) for recovering the oil that deposits on the wall (12), and a separator partition separating the recovery channel (14) from the incoming gas flow channel (10), the flow channel (10) being defined by a first cylinder (16), the oil recovery channel (14) being defined by the first cylinder (16) and by a second cylinder (18) surrounding the first cylinder (16), the separator partition being formed by the first cylinder (16), the wall (12) forming an end wall of the second cylinder (18).
