The piston-rod 7 moves outward (in the released position), opening the door of the vehicle. Compressed air from the left cavity 5 of the cylinder 4 is pressed into the channel 3 and through the valve 13 and the channel 8 into the atmosphere.The electrical control signal is absent (see Fig. 2).Under the action of the working pressure, the supply, this working pressure supplied through the valve "open" 13 enters the channel 3 and the left cavity 5 of the cylinder 4, the piston-rod 7 is moved inward (in retracted position), closing the door of the vehicle. Compressed air from the right cavity 6 of the cylinder 4 is pressed into the channel 2 and through the valve 14 and the channel 9 into the atmosphere.The electrical control signal is absent. The drive shaft manual duplication 22 is pressed (see Fig.3).When the pressing rod drive manual duplication 22 (buttons 28) valve "open" 14 is moved to the leftmost position, the locking seal valve moves away from the saddle straddle sleeve, opening the flow of the operating pressure in channel 2 and the cavity 6 of the cylinder 4. In the cavities 5 and 6 of the pneumatic cylinder are set to the same working pressure, but because of differentialmode of the piston-rod 7 the latter is moved to the extreme left (released) position, opening casement doors of the vehicle and squeezing compressed air from the cavity 5 of the cylinder 4 into the channel of the head 10.Down the drive shaft 22 automatically is now a spring-loaded locking ball 20 by entering it in the annular tapered groove 27. When precieux, when this annular tapered groove 27 of the rod 22, in addition to fixing, at the same time provides a preload valve seal valve 14 to the right saddle straddle the sleeve, providing a snug fit and tightness of the valve. Sash doors remain open.The return of the drive rod manual duplication 22 to its original position and its "unfixing" manually using the button 28 or by applying an electrical control signal, wherein the command working pressure of the air entering the channel 11, the effect on the working area of the drive rod 22 and moves it. When moving the annular tapered groove 27 of the rod 22 against the force bogatoi spring 24 correction mechanism 21, squeezes shut-off ball 20 of the fixing device 17 into the guide bore 18 of the housing 16.
