Abstract

The present invention relates to a deaerating and aerating device (19) for an internal combustion engine (1) for discharging blowby gas out of a crankcase (3), comprising a first line (20) which is connected at one end to the crankcase (3) and at the other end to a fresh gas line (7) downstream of a supercharging device (10) and which contains a deaerating valve (23), and a second line (21) which is connected at one end to the fresh gas line (7) upstream of the supercharging device (10) and at the other end to the crankcase (3) and which contains a throttle device (28) and, parallel thereto, a non-return check valve (29) which provides a blocking action in the direction of the crankcase (3).
