(Fig. 1), and it is returned to it by the cylinder unloading mechanism 51.

Pneumogrive installation for filling cylinders with liquefied gas works as follows.

An empty cylinder 9 (Fig. 1) enters the floor conveyor 50 on the chain conveyor 19 of the loading mechanism 1, moves into the loading zone and turns on the end valve 31. The pneumatic signal arrives at the input of the end valve 30 (Fig. 3) to the control valve pneumatic valve 34 and through pneumatic element OR 37 and pneumatic choke 41 to control valve 42 of hydraulic distributor 22. At that, pneumatic valve 34 switches and connects control valve 45 of hydraulic distributor 22 to the atmosphere, and hydraulic valve 22 closes It feeds oil through the flow controller 21 to the hydraulic motor 18. The latter stops the chain conveyor 19 (FIGS. 1 and 2) together with the cylinder 9 in the loading zone.

As soon as the next weighing device 49 is combined with the cylinder loading zone, the stop -47 (FIG. 3) switches on the end valve. The pneumatic signal passes into the control cavity 28 and switches the valve. 15. Compressed air enters the piston cavity of the pneumatic cylinder 8. Rise occurs the cylinder 9 of the guide 10. Compressed air enters Q through the pneumatic line into the control cavity 17 of the pneumatic distributor 7 and switches it. The compressed air passes through the pneumatic line 3 into the piston cavity of the executive pneumatic cylinder 2, which moves along a flat guide 10 points 9 into the weighing device 49. At the same time, the compressed air through the pneumatic line 39 through the pneumatic element OR 37 and the throttle 41 enters the control cavity 42 of hydraulic distributor 22, duplicate pneumatic signal

The hydraulic cavity 45 of the hydraulic distributor 22 switches it and opens the oil supply through the flow regulator 21 to the hydraulic motor 18. The chain conveyor 19 is turned on and supplies the next cylinder to the loading zone. The loading cycle is repeated.

The throttles 5, 6, 13 and 14 regulate the forward and reverse speeds of the pneumatic cylinders 2 and 8, the flow controller 21 regulates the speed of the hydraulic motor 18 in order to obtain the required speed of the chain conveyor 19 of the loading mechanism. The throttle valve 41 regulates the deceleration time of the switching of the hydraulic distributor 22, thereby eliminating the hydraulic shock and a smooth start of the hydraulic motor.
