Abstract

The device comprises a tube (1) connected to an air supply channel (2) and having a casing provided with holes for the air supplied to it. The tube also contains a perforated choke plate that divides the inside of the tube into two chambers with the same size.

Description

75 20 25 523 947 Uppfinningen förklaras nedan med hänvisning till bifogade ritningar, i vilka figur 1 visar en axonometrisk bild av tilluftsdonet, figur 2 visar tilluftsdonet sett från änden, figur 3 visar utströmningen av inluft i ett i och för sig känt tilluftsdon, figur 4 visar tilluftsdonet enligt uppfinningen i delvis skärning, figur 5 visar en skärning längs linjen V-V i figur 4, och figur 6 visar strypskivan. The invention is explained below with reference to the accompanying drawings, in which Figure 1 shows an axonometric view of the supply air device, Figure 2 shows the supply air device seen from the end, Figure 3 shows the outflow of intake air in a per se known supply air device, Figure 4 shows the supply air device according to the invention in partial section, figure 5 shows a section along the line VV in figure 4, and figure 6 shows the throttling disc.

Tilluftsdonet består av en làngsträckt rörkonstruktion l, anslutits till tilluftskanalen 2. Höljets ena hälft är för- sedd med tilluftshàl, 4 och 5.The supply air device consists of an elongated pipe construction 1, connected to the supply air duct 2. One half of the housing is provided with supply air holes, 4 and 5.

Tilluftens hàlsektor är 180 grader, men den kan vara antingen SOIII så som visas i figurer 1, 2, mindre eller större, exempelvis 360 grader. Rörkonstruktionen l har en perforerad 4 strypskiva 3, som delar rörkonstruktio- nen i två lika stora kamrar. Strypskivan 3 är belägen trans- versalt i rörkonstruktionen. Enligt test har det påvisats att tilluften strömmar ut enligt pilarna i figur 4 väsentligen vinkelrätt från ytan av tilluftsdonets hölje. Detta beror på att strypskivan förorsakar turbulens inne i tilluftsdonet, såsom visas med pilar i figur 4.The hollow sector of the supply air is 180 degrees, but it can be either SOIII as shown in Figures 1, 2, smaller or larger, for example 360 degrees. The pipe structure 1 has a perforated 4 throttle plate 3, which divides the pipe structure into two equal chambers. The throttle plate 3 is located transversely in the pipe construction. According to tests, it has been shown that the supply air flows out according to the arrows in Figure 4 substantially perpendicularly from the surface of the housing of the supply air device. This is because the throttle plate causes turbulence inside the supply air device, as shown by arrows in Figure 4.

Ifall tilluftsdonet har en längd på exempelvis upp till 4500 mm, kan flera strypskivor monteras i rörkonstruktionen så att stora rörkonstruktionen uppdelas i flera väsentligen lika kamrar. p:\patranor\docs\doclemp\slutföreläggande.inLdoc, 2004-02-27If the supply air device has a length of, for example, up to 4500 mm, several throttle plates can be mounted in the pipe construction so that the large pipe construction is divided into several substantially equal chambers. p: \ patranor \ docs \ doclemp \ slutföreläggande.inLdoc, 2004-02-27
