Abstract: In a reciprocating internal combustion engine in which a camshaft for actuating the gas exchange valves is disposed in a space, which is in communication with the engine crankcase to receive the vent gases therefrom, and the camshaft includes an axial passage and at least one radial bore and the axial passage is in communication with the engine intake duct for drawing vent gases from the crankcase to the engine intake duct through the camshaft, a disc provided with a radial disc bore is mounted onto the camshaft such that the disc bore is in alignment with the radial camshaft bore and the disc has an axial bore extending therethrough so as to intersect the radial disc bore adjacent the circumference of the disc, whereby vent gases entering the axial disc bore are accelerated in the axial bore and, upon entering the radial bore, oil particles are discharged outwardly through the radial disc bore while the gases flow inwardly through the radial disc bore to the camshaft passage and to the engine intake duct.
