A centrifugal oil mist separator device integrated into an axially hollow camshaft of an internal combustion engine should permit a good separation effect. To this end, a device is provided whereby the camshaft (101) is provided on a first end with radial oil mist inlet openings (106) for oil mist to be introduced into the axially hollow space (102) in the camshaft (101) and on the second end, for discharge with a radial oil discharge channel (112) for oil separated as liquid phase on the one hand and with an axial gas discharge channel (113) on the other hand for oil mist stream remaining after the liquid component has been separated, a centrifugal oil mist pre-separator is provided upstream from the radial oil mist inlet openings (106) as a pre-separator (107) fixedly connected to the camshaft (101), and within the axially hollow space (102) in the camshaft (101) a spiral flow generating device (108) is provided as the final separator.
