It is proposed a device for venting a crankcase of a supercharged internal combustion engine of a motor vehicle, the one with the crankcase of the internal combustion engine (10) in communication and in an intake passage (20) of the internal combustion engine opens vent line (38) and in the ventilation line (38) arranged pumping means (42, 42 '), the blow-by gases from the crankcase of the internal combustion engine (10) sucks and pressure of the blow-by gases in the vent line (38) to the charging air pressure in the intake passage (20) of the internal combustion engine increased, said vent line (38) downstream of an exhaust gas turbocharger (12) and a charge air cooler (26) into the intake line (20) of the engine opens and the pump means (42, 42 '), a piston pump is relatively at a low mass flow rate can achieve high output pressures.
