Definitions

the percentage of the total cross section of the openings in the stin side of the outer housing facing away from the terminal box is greater than the percentage of the total cross section of the openings in the jacket of the outer housing.
This configuration gives the outer housing a basket-like design in its lower region, the contours of which, in contrast to known devices equipped with flaps, remain the same regardless of the blow-out direction.
the flow pattern is also more spatially uniform than in the known air outlet with the double valve open.
an embodiment of the invention provides that the jacket of the outer housing, the end face of the outer housing facing away from the connecting piece, the transition piece of the outer housing and the jacket of the inner housing are made from perforated sheets.
the perforated sheets are easy to manufacture components and result in air outlet surfaces with an extremely low-turbulence displacement flow.
the device consists of an outer housing 1, which can have the shape of a hexagonal prism and is defined radially by a jacket 2, over the surface of which openings 3 are provided in a uniform distribution.
An inner housing 4 is arranged concentrically within the outer housing 1 and is likewise defined by a jacket 5, over the surface of which openings 6 are provided in a uniform distribution.
a connecting piece 7 is connected coaxially to the inner housing 4, opens into a core space 8 and projects over an end face 9 of the outer housing 1.
Openings 11 are also provided in a uniform distribution over an end face 10 of the outer housing 1 facing away from the connecting piece 7.
a cone-shaped impact body 14 which is height-adjustable via a rod 13, is pointed, which points with its tip in the direction of the end face 12 of the inner housing 4.
the impact body 14 can be moved up to the stop against a sealing ring 15 projecting radially inwards on the inner housing 4, so that the air jets - as shown in FIG. 1 - only flow horizontally from the device into the room.
