Swirl inducing outlet

摘要

The outlet has an outlet disc (1) which contains slots (12) and apertures (13). A funnel-shaped component (3) in the edge strip (2) forms an annular gap (10) with it for the disc. Distance-pieces (1) can be inserted in the gap, these being interchanged so as to vary the gap width. A fixing device (4) for the disc can engage in a bush in a cross-member (5), which fits in components in the walls of the funnel-shaped component. The member can be closed at the sides by end-pieces and the apertures in the disc can be of different shapes and sizes.
