With respect to the direction of flow of the water in the main pipe 9, an upstream side of the system 1, located on the side of the water inlet port 3, and a downstream side, located on the side of the port of water, are defined. exit 7.
- the system 1 comprises a main chamber 1 1 in which is movable a piston 13 provided with a rod 130.
- the piston 13 divides the chamber 1 1 into two parts.
- a first portion 15, said upstream portion, located on the left side of the piston 13 in Figure 1, is connected to the inlet port 3 by a pipe 17.
- a second part 19, said downstream part, which is on the right side of the piston 13 in Figure 1, is connected firstly to the product inlet port 5 by a pipe 21, and secondly, to the main pipe 9 by a pipe 23.

- the elements common to the first embodiment bear the same references and operate from the same way. Only the differences with respect to the first embodiment are detailed below.
- the system 1 comprises a jack 31 adapted to actuate the rod 130.
- the cylinder 31 comprises a piston 310 and a rod 312.
- the piston 310 is slidably mounted in a chamber 33.
- the rod 312 protrudes out of the chamber 33 on the side of the rod 130.
- the piston 310 is opposite the rod 130.
- the cylinder 31 is pushed by an elastic element, such as a spring 314, to a retracted position , shown in Figure 2, wherein the rod 312 is almost entirely located in the chamber 33.
- the chamber 33 is connected by a pipe 35 to the main pipe 9.
- a valve 37 allows the entry of water to from the main pipe 9 in the chamber 33 via the pipe 35 in order to push the piston 310 towards the piston 13, against the force of the spring 314, towards a position exiting the cylinder 31, shown in Figure 3, wherein the rod 312 protrudes from the chamber 33.
- the chamber 33 can be emptied of the water it contains by a pipe 39 which joins the main pipe 9 downstream of the valve 27.
- a valve 41 makes it possible to open or close the passage of the water of the pipe. 39 to the main pipe 9.
- the valve 37 is closed, which prevents the arrival of water in the chamber 33.
- the spring force 314 therefore pushes the cylinder 31 back into its retracted position.
- the valve 41 is open and the water contained in the chamber 33 is expelled through the pipe 39 to the main pipe 9, as shown in FIG. 4.
- the system 1 may incorporate an auxiliary chamber 43.
- the auxiliary chamber 43 is fluidly connected to the upstream portion 15 of the main chamber 1 January.
- a valve 45 opens or closes the passage of water between the upstream portion 15 and the chamber 43.
- the auxiliary chamber 43 comprises a piston 430 which is movable between a first position, shown in Figure 2, in which it is pushed by an elastic element, such as a spring 432, against the end of the chamber 43 located on the side of the valve 45, and a second position, shown in Figure 3, in which the piston 430 is pushed back, against the force exerted by the spring 432, opposite the valve 45.
- the auxiliary chamber 43 is also connected, via a pipe 47, to the main pipe 9 downstream of the valve 27.
- the pipe 47 joins the pipe 39.
- the pipe 47 can join the main pipe 9 independently of Line 39.
- the system 1 operates as follows.
- the regulation device 60 is configured so as to let a certain quantity of water pass into the upstream portion 15 of the chamber 1 1, so that the piston 13 is pushed towards the downstream portion 19 and expels the chemical in the pipe 23.
- the valve 29 is open in this configuration.
- the valves 45, 37 and 41 are closed in this configuration, so that the mixture of water and chemical passing through the main pipe 9 is ejected through the outlet port 7.
- the system 1 is controlled to implement a second configuration, called filling, as shown in Figure 3.
- the valve 29 is closed and the regulation device 60 is configured to to prevent the passage of water to the upstream portion 15 of the chamber 1 1.
- the valves 45 and 37 are open.
- the water that continues to circulate in the main pipe 9 thus fills the chamber 33 via the pipe 35, according to the arrows F3, and pushes the cylinder 31 against the force of the spring 1 14 in its extended position, so that the rod 312 pushes the piston 13 in the upstream portion 15, according to the arrow F2.
- This movement of the piston 13 has the effect of expelling the water contained in the upstream portion 15 towards the chamber 43, and pushing the piston 430 away from the valve 45.
- the output port 7 of the system 1 can then be cleaned, as shown in Figure 4, using the water accumulated in the chambers 33 and 43.
- the valve 37 is closed and the valve 41 is open.
- This causes the springs 314 and 432 to push the pistons 310 and 430 according to the arrows F4, which drive the water contained in the chambers 33 and 43 in the pipes 35 and 47, according to the arrows F5.
- This makes it possible to clean the part of the main pipe 9 located between the valve 27 and the outlet port 7.
- the system 1 can also be used in another configuration shown in FIG. 5, and in which the valves 29, 37 and 45 are opened simultaneously, so that the water circulating in the main pipe 9 fills the downstream portion 19 of the main chamber 1 1 through the pipe 23.
- This allows to clean the downstream part 19, for example in the case where a different chemical must be used.
- the chemical reservoir 100 is previously disconnected from the input port 5, which is closed by means not shown.
- the filling of the chamber 33 allows the movement of the piston 13 towards the upstream portion 15 along the arrow F2, which causes the suction of water in the downstream portion 19 of the main chamber 1 1, via the pipe 23 along the arrow F6 .
- valve 37 When the filling of the downstream part 19 of water is completed, to empty the upstream part 19, the valve 37 is closed, the valve 41 is open and the regulation device 60 is configured to let the water in the upstream part 15 of the chamber 1 1, as shown in Figure 6.
- the cylinders 31 and 430 are therefore pushed by the springs 314 and 432 to their retracted position.
- the piston 13 is pushed towards the part downstream 19 by the water entering the upstream portion 15, which allows to drive the water contained in the downstream part 19 to the main pipe 9 according to the arrows F7.
- the system 1 can also be controlled in such a way that the chemical remaining in the downstream part 19 can be transferred again to the tank 100.
- the valve 29 is closed and the device 60 controlled so as to let water to the upstream portion 15.
- the piston 13 is pushed to the downstream portion 19, which has the effect of expelling the chemical contained in the downstream portion 19 to the pipe 21, then in the tank 100 according to the arrow F8.
- the device 60 and the valves 29, 37, 41 and 45 can be controlled centrally by the user to switch on the various operating modes of the system 1, for example by an electrical circuit controlled from a control member.
- the system 1 does not include cylinder 31 or auxiliary chamber 43, but includes a cleaning circuit 50 connected to the main line 9 upstream of the pipe 17, and connected to the downstream portion 19 of the chamber 1 1.
- the passage of water to the cleaning circuit 50 is controlled by a valve 52.
- the system 1 also comprises a valve 54 located on the main pipe 9 upstream of the pipe 17, and which makes it possible to block the passage of water towards the downstream part of the main pipe 9.
- the system 1 operates as follows. To clean with water the downstream portion 19 of the main chamber 1 1, the valve 52 is open and the valve 54 is closed. The valve 29 is also closed. The water is thus directed, via the cleaning circuit 50 along the arrow F9, to the downstream portion 19 of the chamber 1 1, which has the effect of pushing the piston 13 to the upstream portion 15 along the arrow F2.
