DESCRIPTION:
BRIEF SUMMARY
BACKGROUND AND SUMMARY OF THE INVENTION
The invention relates to a drying cartridge in general and more specifically, to an Air Drying Cartridge for Vehicles' Compressed-Air Brake Systems.
In the case of drying cartridges of the concerned type, which, according to their use, are called "disposable cartridges", a face cover is fastened to the underside of a pot, for example, by a flanged connection. The face cover having a thread in the center for fixing the cartridge on a dryer casing. Devices are provided which prevent escape of the granulates or drying agent through the center to the outside. Thus, the drying cartridge can be handled without special measures. That is, after being unscrewed from the dryer casing, it can be stored intermediately or be used as a disposable part. The face covers used for such drying cartridges or their flanged connections with the pot of the drying cartridge are considered to result in high expenditures with respect to the material and with respect to the thickness of the material. Because of the unreleasable flanged connection, a separate disposal of the filter material and the material of the granulates and the reuse of the other piece parts situated in the drying cartridge is possible only at disproportionately high expenditures. The drying cartridge can therefore only be used as a disposable part.
During the manufacturing of drying cartridges of the concerned type, the demands for an environmental compatibility which is as extensive as possible become increasingly important. Thus, because of the long-term effect of rust, it is undesirable to store contaminated drying cartridges, that is, drying cartridges enhanced with oil particles, in increased numbers as disposable parts and to take them to a waste dump.
Thus, it is an object of the invention to develop a drying cartridge of the concerned type with heightened environmental protection. In particular, it should be possible to carry out a low-cost disposal of the filter and granulate material situated in the drying cartridge without the requirement of carrying out time-consuming dismantling of the pot of the cartridge. On the other hand, it must be ensured that, after having been detached from the dryer casing, the drying cartridge can be handled as a structural unit without any escaping of filter material or granulate material from the interior of the cartridge.
These objects are achieved by a face cover releasably fastened to a central screw of the cartridge and displacable relative to the outside of the pot to allow releasing of the fastener assembly.
Despite the use of the face cover which can be displaced relative to the outside pot and is therefore releasably connected with the latter, it is possible to handle the drying cartridge as a structural unit separately from the dryer casing. On the other hand, as a result of the displaceability of the face cover, it is possible to release the connection consisting of the clamping or frictional fit with respect to the central screw of the cartridge so that, if required, it will be possible to remove all piece parts of the cartridge at low cost and therefore dispose of the filter material and of the granulates.
Advantageous developments and further developments are indicated in additional claims.
In the following, the invention is explained by means of an embodiment with reference to the single FIGURE.
BRIEF DESCRIPTION OF THE DRAWING
The FIGURE is a sectional view of the drying cartridge according to the principles of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A drying or filter cartridge according to the invention which is illustrated in the FIGURE, has an outer pot 1 in which an inner pot 5 is situated which contains a drying agent 3. A central screw 7 extends centrally through the drying cartridge and includes a threadable end 9 at its lower end for the screwed connection of the drying cartridge with the dryer casing 11 partially illustrated in the FIGURE. A cover 15, having openings 13, is at the top of the inside pot 5 and displace
