A side-channel compressor includes a rotor having transport blades, and an injection nozzle for introducing a cooling liquid into a transport section of the compressor. Damage to the transport blades by droplets of liquid can be avoided by the providing the injection nozzle at the part of the compressor housing forming the side channel. The injection nozzle directs the coolant into a side channel space which is free of the transport blades.
