The ring canal blower has a housing with a lateral canal in front of one or both front sides of a rotor for compressing gases as well as intake and pressure connection stubs which are connected directly to each other via the canal or canals. In order to prevent a heat build-up, the housing has an outlet for hot gas located between the intake and pressure connection stubs as viewed in the direction of rotation of the rotor as well as an inlet for cool gas. The inlet for the cool gas communicates with the hot gas outlet via the rotor compartments that pass by. The outlet and inlet serve to draw off the hot gas disposed within the rotor blade compartments while replenishing these compartments with cool gas. |
