Patent application Note; Company H. Krantz GmbH & Co., Krantzstrasse, 5100 Aachen Designation: "swirl outlet"

ORIGINAL INSPECTED

The invention relates to a swirl outlet made of an outer tube and a core tube arranged concentrically in it with one another Ring cross-section between the outer diameter of the core tube and the inner diameter of the outer tube, radially extending swirl blades and a valve disk which is mounted outside the core tube and can be introduced into the core tube on the inflow side, the outside diameter of which corresponds to the inner diameter of the core tube, the core tube having a tube cross-section at the tube end on the inflow side Rounding that reduces the size in the direction of flow and at the end of the pipe on the outflow side an orifice that extends into the free ring cross-section has, while the outer tube has a diameter to the outlet side Has end of the pipe enlarging rounding.

Such swirl outlets are known and allow a part of the air volume flow horizontally and another part vertically. The ratio of the two partial volume flows can be vary by changing the position of the valve disk.

Finally, swirl outlets are also known in which by displacement a baffle plate, the total volume flow is continuously variable between a horizontal and a vertical discharge direction can be changed.

The invention has for its object to provide a swirl outlet of the initially To improve the type described so that it is possible, if necessary, the horizontally blown air jets of the to induce vertically blown injector jet and thereby deflect it.

To solve the problem, it is proposed that the diameter of the outer tube be enlarged towards the end of the tube on the outflow side Rounding merges into a concentric collar, .der of a cylindrical section connected to the rounding, a frustoconical section connected to the cylindrical section that widens in the direction of flow and one on the frustoconical section connected annular disc consists.

The inventive design of the outlet is achieved that the horizontally blown air jets are induced and thus deflected by the vertically blown injector jet can, the air volume flow of the injector jet in a known manner by changing the position of the valve disk can be changed. With this change, the induction effect of the vertically blown injector jet and also changes thus the direction of the entire air volume flow. With the core tube closed by the valve disk (volume flow of the injector jet = »0) the air jet emerging from the ring cross-section occurs more or less normal from the outlet axis away into the room. By increasing the air volume flow through the Core tube enters the room as an injector jet, the total air jet is more concentrated and enters the room more steeply. away a certain air volume flow of the injector jet becomes the total volume flow blown almost concentrically to the beam axis vertically downwards into the room.

It is advisable to design the adjustability of the valve disk in such a way that that the injector jet can be regulated either in small steps or, however, preferably continuously, the regulation can be done with suitable control means. If necessary, a one-time setting of the valve disk to the desired Drive success. A regulation without external energy, z. B. with the help of a thermostat is also possible.

According to a preferred embodiment of the twist outlet according to the invention, the opening angle et <j _{e8 of the} frustoconical section is 20 - 60, the ratio of the height h of the cylindrical section to its diameter D 0 - 0.4, the ratio of the diameter d of the core tube to the diameter D 0, 1 - 0.5, the ratio of the outer diameter d. of the diaphragm to the inner diameter d of the core tube 1.5-3 and the ratio of the height h. of the washer 13 to the diameter D - 0.01.

With certain values of OC and h ι D it can be achieved that the radially blown air jets without an injector jet do not spread horizontally, but at an angle / 0. The larger * and the ratio h: D, the larger is ⁰ ^ .. This means that in high rooms the supply air is not blown out horizontally, but more or less steeply straight down into the room.

With the twist outlet according to the invention, the air volume flow can be adjusted continuously from the horizontal to the vertical direction.

Air can be flushed through.

In the drawing, a swirl outlet according to the invention is shown as an exemplary embodiment shown. Show it:

The swirl outlet consists essentially of an outer tube 1, which is penetrated by a perforated plate 2 in the upper region of its free cross section. The outer pipe 1 has the pipe end on the outflow side a rounding 3 increasing the diameter.

A core tube 4 is arranged concentrically in the outer tube 1 whose outer circumference twisted blades 5 radially over the between the outer tube 1 and the core tube 4 extending annular space remaining.

As Figure 2 shows, the over the ring cross-section are blown in Air jets deflected by about 90 to the center axis of the swirl outlet when the valve disk 8 blocks the cross section of the core tube 4 and thus there is no need for an injector jet.
