に移動できる。When the IRJ diversion valve 16 is closed and pressure is removed through the hose fitting, the spring 46 forces the debris plug back into the closed position of FIG. Air pressure within chamber 52 is vented to the main body of chamber 28 through passage 54 and then out through passage 40 of the seal. Closing of the valve is done at such a speed that the air pressure in each chamber (52 and 28) can be released, so that the dust flap can be moved to the closing device.

る。Debris plugs are necessary and immovable to keep impurities in the supply air, such as insects, dirt, and other miscellaneous substances, from entering the valves located downstream of the hose fittings. As such, the air system in the tractor-trailer combination is protected by a garbage plaque that automatically closes when the supply air through the hose fitting is interrupted.

The medium heat passage 92 of the seal 74 is closed. Also, a safety guard l17. ,) 771 part 94 is in close engagement with the seal 74 L-r:) 3. The indicator rod is also placed in the plaque 1.1 (L) in the same manner as the example in FIG. The collar 90 is made of hose silk and the seal 74 in the body 70 of the hand is opened 1) and the collar 8 is inserted in the annular groove 98.
A central passageway 964 and ending at 0 and 7 are located opposite each other. The seal 99 is located at one end of the plug 90 and the collar 8[]. The dense layer between the collar and the 1st target plaque under the sticker 99 is 1. Since there is no supply, the pressurized air from the groove 9B is suspended from between the matching surfaces of the two electric phases, and the dust-preventing flak and collar are used as in the chamber 52 of FIG. 1. [formed between opposing surfaces] tb) 1 reaching the chamber 100, the dust plug has the same seal as shown in the example of Fig. 1 in the collar of the debris plug 1, when activated, 41 .2 In the closed position shown in Figure 2, the debris plug leaves an opening 11 in the seal of the hose fitting. In the valve closing device shown in FIG. 2, no air is supplied to the air inlet 1-1. When air is supplied to the Bose joint, the air inlet L172 acts as the introduction 1-21 and I7, and the air is first supplied to the opposite surface of the dust prevention plug 90.J

This is a small point in Komei. When air pressure is supplied to the hose fitting, the dust guard 111 plug in the normally closed position 111 is automatically pulled 1. A, 77, 'hl free flow of air pressure through the hose fitting. The debris plug automatically closes when air is removed from the hose fitting. In this way, the shroud plug prevents impurities in the supply air from passing over the hose fitting. By closing Inlet II to the hose fitting, the valve server downstream of the hose fitting is protected from impurities in the air system.
