Flow switching element; has Coanda tulip, at least two outlets and displacement body with even flow surface joined to casing, with separating edge defining area between casing and flow surface

摘要

The switching element has a feed channel (1), a Coanda tulip (5), at least two outlets (11,12) and a displacement body (6). The displacement body is arranged in the area of the Coanda tulip and is provided with an essentially even flow surface (7). A casing (8) is joined to the flow surface in the direction of the flow. The transitional area between the flow surface and the casing is defined by a separating edge (15).
