Patent ID: 10808719

Abstract:
A blower arrangement comprising an impeller, which has an axial intake opening formed by a cover plate covering impeller blades at least in sections, by an intake nozzle connected upstream of the impeller, which extends at least in sections into an overlap section in the intake opening of the impeller, wherein a circumferential nozzle gap is formed between the intake nozzle and the cover plate of the impeller, an outer nozzle, which is arranged spaced apart in the radial direction in relation to the impeller and the intake nozzle and enclosing them in the circumferential direction. A first circumferential radial gap is provided between the outer nozzle and the intake nozzle, which forms an inlet nozzle duct extending in the flow direction. A second circumferential radial gap is provided between the outer nozzle and the cover plate of the impeller, which forms a gap duct extending in the flow direction.
