The disadvantage of this general design is that when there is a drop in temperature or pressure in the flow direction behind the separator, a larger amount of moisture is separated from the air in i'orai by droplets. These droplets can interfere with the proper Arbuiten of Inatrumenten, and they may also have adverse effects on plants, where the humid air is supplied, "The second group, the ohemiaoben drying devices in which the just-strip-mentioned does not occur include ₀ However, a drawback of such ohewisohen Xrooken devices in that they spray a lot of fluff, and that "they are generally expensive"

Can Another known construction of a chemical treatment device comprises a He ilahalt of sohwerer construction with a controlled by a two-way valve to JSinlaüo The container is designed so he DAT two juxtaposed groue ße.tiandlun> _(spatronen simultaneously record, each of which usually so hard Let "you need a mechanical device to lift the cartridge". These cartridges are lowered into the container one at a time, and the container is usually provided with a cover made up of two independent ropes Actuating the two-way valve in a gecigiote way, it is possible to direct the liquid to be treated to one of the putrons, while the other cartridge is removed from the “container and a fresh cartridge is replaced” ₆ ? Valve ₈₀ actuated, datt the

External opening 4 of the two end walls 1. In this way there is a closed flow path which extends from the inlet opening 4 via the cartridge to the external opening. The indicator element is visible through an opening in the housing, and as soon as the cartridge is exhausted or used up, an operator niauut a fresh puttrone, which is in the upper rope of fig. 2 and introduces it through the upper housing opening into the mentioned channel. If this "fresh cartridge is pressed downwards, the used cartridge, ie matt fi ^. 2 the lower of the two cartridges is ejected, and at the same time a new cartridge is brought into alignment with the openings 4 of the two end walls 1 essentially completely the jintweiohen of air during the replacement of the cartridges and afterwards, i.e. when the new cartridge 5 is in its use division

In Fig. 3, Juan sees two cartridges of a modified embodiment. Each of these cartridges, designated 11, has one cylindrical shape »In this case, each cartridge is provided with an annular perforated sealing element 12 at each end, and to avoid a greater loss of compressed air during replacement To prevent the cartridges, is between the two cartridges 11 during the exchange process «in a separate package or Sealing element 15 arranged. The sealing member 13 has a huniform cross-section, i.e. if one looks at this sealing element in the sight in which the device is from the

109842/1388

Compressed air is flowed through, one appoints, if the Diohbungselement has awei concave, circular arc-shaped geicrüiiuute Aueeparungen H, which fit the Ouiriiiform of the two circular cartridges 11} Furthermore, the sealing element has two end faces 15, which according to Fig. 2 with the inner surfaces 3 of the housing facing them In this way, the escape of compressed air during the replacement of the cartridges is essentially prevented, and it should be noted that when the cartridge is in its use position in the housing, the annular sealing element 12 on each end of the cartridge the relevant housing opening 4 is hollowed out, so that the escape of compressed air is prevented.

Fig. 4 shows an arrangement in which the upper part of the cylindrical wall of a housing or a support 17 »the delimiting a channel of circular cross-section, is provided with an inlet nozzle 16 and a second outlet nozzle 16 arranged at a distance therefrom. The associated, in Fig. 4A shown cartridge 18, which has a corresponding circular cross-sectional shape, is with an inlet opening 19 and one Opening 19 provided. The cartridge 16 carries on both Sides of each of the two openings 19 each have a circular sealing element 20, and these sealing elements work with the cylindrical inner surface of the housing 17 in order to Prevent air from escaping from the inlet port the cartridge flows to the discharge port. See the distance the openings 19 of the cartridge is the same as the distance between the Anuchluba benefits 16. It should be noted that given

If necessary, both the housing 17 and the cartridge 18 can form such that these parts have a rectangular cross-sectional shape obtain.

When the cartridge 18 is in the housing 17 in its utility compartment, air flows to the cartridge via one set of openings 16 and 19 to pass the cartridge and then escape via the second set of openings 16 and 19. When a new cartridge is inserted into the housing in the longitudinal direction in such a way that the old cartridge is removed from the housing, the sealing elements first close the flow path for the compressed air until the new cartridge is in its position of use with the sealing elements 20 automatically ensure daii the compressed air to the desired flow path follows "thus it is possible to replace the cartridge, can _o escape without DAT coarser compressed air quantities also, the housing 17 and the cartridge 18 can be made of a duroh" eiohtigen i aterial or provided with transparent windows so that an ohemical indicator provided in each cartridge can be observed to determine when the cartridge in use must be replaced. It should be noted that the housing 17 and the cartridges 1b can also have a circular cross-sectional shape.

In Fig. B a housing 21 is shown, which at diametrically opposed points in the middle between its loading coaxially arranged inlet and outlet openings or nozzles 22 and rarely each of these nozzles on the inside with a filngnut each is provided.

Elastic sealing rings 23 are built into these grooves, and each of the cartridges 24 (Figs. 51 and 5B) has cylindrical end sections 25 ₁ which can work with a tight fit with the sealing rings 25; this Jundabeohnitte 25 is approaching a length which is somewhat greater than the axial distance between the two associated sealing rings 23 in de »Exactly · 21 · The middle cable 26 of the cartridge 24 is provided with openings 27 with the inlet and outlet openings 22 of the housing 21 work together. In addition, a guide member 281a extending in the longitudinal direction is provided inside the cartridge in order to lengthen the flow path along which the compressed air in the cartridge can move.

If a new cartridge 24 is installed in this embodiment the two pairs of sealing rings 23 at the ends of the housing 21 keep a perfect * free seal upright, which also remains "if you see the new cartridge is in its usable compartment.

Jöei the exemplary embodiments described so far exist the danger that the pressure air will remove the used cartridge and the fresh cartridge during replacement «. Assumes, as shown in FIGS. 4 and 4A, the reohte opening 16 forms the air inlet opening, and since "the illustrated cartridge 18 is inserted to the left into the housing 17" Cartridge used up almost instantly with movement on the left the entrance opening 16 ait de «Baua swisoaen de» left Diohtungseleiaent 20 of the new cartridge and the nioht shown right Diohtungseleaent 20 of the used
