ABSTRACT:
A ring channel blower for combustion air conveyance in heaters, preferably motor vehicle heaters. With this ring channel blower, there is a gradual transition from the pressure area to the discharge opening of a ring channel that is covered at a side of the ring channel proximate an impeller by an upstream extending section of a cross piece-shaped interrupter. Suitably, a sickle-shaped or sail-shaped section covering the ring channel is provided which, starting from the inner edge of the ring channel, approximately at the height of the projection of the discharge opening on the ring channel, uniformly tapers in a direction opposite the compression direction in the ring channel of the ring channel blower and ends in a type of rounded tip on the outer edge of the ring channel of the ring channel blower. Further, a section of the interrupter is provided at the inlet area that partially covers the inlet opening and which, starting from the outer edge of the ring channel, extends approximately tangentially to the inner edge of the ring channel. This section is simultaneously inclined slightly toward the base of the ring channel. A bypass between the discharge opening and the inlet opening can be provided in the form of an elongated slot in a partition portion of the interrupter, the free opening cross section of which is adjustable via a setscrew.
