Wagon toilet device operation

In the initial period of time, when the wagon toilet equipment was turned on, there is no signal for electrically controlling the electric distributor from the electronic control unit. At the same time, compressed air enters through the pressure regulator 21 and the electric air distributor 11 to control the unloading 9 and drain 10 valves and closes them, and through the electric air distributor 11 to the upper chamber of the pneumatic actuator 25 and lowers the piston 31 with the rod 24 and the membrane 23 to the lower position. When this information about the lower position of the piston 31 is transmitted to the electronic control unit 6 through the sensor 30.

After using the toilet for its intended purpose, the flush button 7 is pressed, the electric signal from which is fed to the corresponding input of the electronic control unit 6, which issues a command to the electric air distributor 11, which supplies compressed air to the control input of the flush valve 8 and opens it. Water under pressure through the filter 32 is fed to the toilet flush 1. After a time limited by the required volume of flushing water, the electronic control unit 6 removes its signal from the electrodistributor 11 and the toilet flush 1 stops. Further, at the signal of the electronic control unit 6, through the first pressure regulator 21 and the electric air distributor 11, the compressed air of the control branch of the unloading valve 9 is discharged and it opens. By means of an electro-pneumatic distributor 11, compressed air is supplied to the lower chamber 27 of the piston pneumatic actuator 25, which, moving the membrane upward with the piston rod, sucks sewage from the toilet 1 into the drain line 5 and into the cavity of the housing 22. When reaching the upper position of the piston 31 by the signal of the sensor 30 through the electronic control unit 6, using the electrodistributor 11 closes the discharge valve 9, and the drain valve 10 opens. When this compressed air is supplied to the upper chamber 26 of the pneumatic actuator, the piston 31 moves down, the rod 24 puts the membrane 23 in the lower position - there is a discharge of effluents from the cavity of the housing 22 into the drain line 5 and then through the drain pipe 18 to the storage tank 19. In at the same time, through the second pressure regulator 28 and nozzle 29, compressed air from the pneumatic line 13 is supplied to the drain line 5, accelerating the movement of sewage into the storage tank 19.

According to the signal of the sensor 30 of the lowermost position of the piston 31 of the pneumatic actuator 25, through the electronic control unit 6, the electrodistributor 11 shuts off the supply of compressed air to purge the drain line, closes the drain valve 10 and turns on, for the time required for the formation of the water shutter, the water supply through the flush valve 8, after which the equipment of the toilet complex returns to its original state.

The filter 34 provides reliable operation of the water equipment of the toilet, and an adjustable pressure sensor 35 - monitoring the functioning of the pneumatic equipment of the toilet.

From the above it can be seen that the introduction of a set of distinctive features of the utility model can improve the reliability of the toilet carriage compared to the prototype.
