The protruding peripheral edge swirl vanes have become known, which is connected to the mantle of a 50 of the frame with the mouth of the passage 1 tubular, coaxially to the air duct an- by an inclined plane, which are attached to the ordered body. During the opening, a funnel-shaped surface is formed with a changing inclination flowing through the tubular body. It should be emphasized that the core jet flows out without a swirl, a swirl is impressed on the air flowing through the inclination of the surfaces that connect the edge of the frame swirl vanes with the mouth of the air passage. The regulation of the diameter in relation to the central axis, the smallest in the upper sentence, is only possible for the core beam, whereby the part is at the point at which the angle α has the insert parts reducing the small cross-section in the pipe, while they are of medium size introduced at the bottom of the shaped body. The throughput is the point at which the angle β is approximately 45 °, and can therefore only be reduced except for the point at which the air flow rate is greatest on the sides at the points where the amount of air carried is reduced; otherwise the angle γ has values of about 60 °.
throughput control is complicated. In addition, this is the special formation of the framework of the
