- the invention relates to valves for the passage of a fluid.
- the invention also relates to soil irrigation.
- the electric programmer is able to move the electrically controlled valves from a closed position to an open position and vice versa.
- the programmer can therefore direct the flow of fluid into the system.
- the programmer opens a solenoid valve, while keeping the other solenoid valve closed. So, we periodically water plots of agricultural soil.

- the valve comprises means adapted so that the flow-sensitive piston remains in the high flow position when the fluid pressure has dropped below the predetermined threshold as long as the outlet of the valve remains in the fluid passage position.
- the valve comprises a spring for keeping the piston responsive to the flow in low flow position.
- the invention also provides a hysteresis fluidic control valve comprising:
- a fluidic control valve having a main duct and a control output
- a hysteresis fluidic valve as previously described, connected to the control output of the fluidic control valve.
- the opening and closing of the fluidic control valve can be controlled by means of the hysteresis valve.
- a hysteresis fluidic control comprising:

- FIG. 8 is a sectional view of a hysteresis fluidic control according to the invention.
- FIGS. 1 and 2 show a hysteresis fluidic valve 10 according to the invention.
- the hysteresis fluidic valve 10 comprises a body 11, formed of a stack 11a, which is here generally cylindrical, provided at its base with a fluid inlet channel 12 and a fluid outlet channel 14.
- the inlet channel 12 and the fluid outlet channel 14 are in the same axis, perpendicular to that of the stack 11a.
- the hysteresis fluidic valve 10 is therefore a straight body valve.
- the hysteresis fluidic valve 10 comprises a corner body.
- the hysteresis fluidic valve 10 also comprises, housed in the chimney 11a, a first piston 16, a seal member 18, a first spring 20 and a knob 22, screwed on the chimney 11a around the first spring 22 , which extend along the axis of the chimney 11a, that is to say here perpendicular to a direction of fluid flow between the inlet 12 and the fluid outlet 14.
- the body 11 comprises a fluid circulation chamber 24, one end of which forms the seat of the seal 18, as can be seen in particular in FIG. 2, in order to prevent the fluid coming from the fluid inlet 12d. reaching the fluid outlet 14 when said seal 18 rests on its seat.
- the first piston 16, the seal 18, the first spring 20 and the button 22 form, with the fluid circulation chamber 24 of the body 11, a valve 26 adapted to take at least one closed position, visible at 2, and an open position, visible in particular in Figure 3.
- a valve 26 adapted to take at least one closed position, visible at 2, and an open position, visible in particular in Figure 3.
- the first spring 20 bears on the first piston 16 and applies the seal 18 against the end of the fluid circulation chamber 24 of the body 11, so as to maintain the valve 26 in the closed position, as seen in Figure 2.
- the hysteresis fluidic valve 10 comprises means adapted for the valve 26 to move from the closed position to the open position when the fluid pressure exceeds a predetermined threshold.
- these means comprise the first piston 16, the seal 18, the first spring 20 and the button 22.
- the first piston 16 comprises a pin 16a which performs two functions: on the one hand, it holds the seal 18 in an annular groove 16b located at its base, on the other hand, it occupies a volume in the fluid circulation chamber. This latter function will be explained in relation to a second piston 30 of the hysteresis fluidic valve 10.
- the hysteresis fluidic valve 10 comprises a second spring 28 and a second piston 30, housed in the inlet channel 12.
- the inlet channel 12 comprises two sections: an upstream section 12a and a further downstream section 12b small diameter than the upstream section 12a, separated by a shoulder 12c.
- the second piston 30 is a hollow cylindrical body, that is to say a longitudinal inner channel, having a bottom 34 at one of its ends and an outer flange 32 at its opposite end.
- the bottom 34 is placed downstream in the fluid flow direction, while the collar 32, around the open end, is placed upstream.
- the second spring 28 is engaged around the second piston 30 and the outer collar 32 serves as a seat for the second spring 28.
- the second piston 30 comprises a plurality of orifices 36 whose role will be described later.
- the hysteresis fluidic valve 10 comprises a tip 38 which serves two functions: externally, it serves as a connection for a pipe (not shown) connected to the hysteresis fluidic valve, internally it serves as a stop on the outer flange 12 of the second piston to maintain the latter in the body.
- the tip 38 is hollowed out of a longitudinal channel which extends the longitudinal inner channel of the second piston.
- the second piston 30 is movable by axial translation in the body 11, between two end positions, according as its outer flange 12 is supported on the end piece 38 or the second spring 28 compressed against the shoulder 12c.
- the second piston 30 Because the outer diameter of the second piston 30 is slightly less than the inner diameter of the conduit which surrounds it, the second piston 30 leaves around it a clearance which allows the fluid to pass through it whatever its position. The second piston therefore never prevents the passage of the fluid entering the valve through the fluid inlet 12.
- the second piston 30 transmits to the first piston 16 the pressure of the fluid present in the inlet channel 12.
- the second piston 30 is sensitive to the flow rate of the fluid passing through the inlet channel 12.
- the second piston is in a detent position that can be seen in particular in Figures 2 and 3.
- the second piston 30 is driven downstream and compresses the second spring 28, as shown in Figure 4.
- the fluid from the fluid inlet 12 s' flows directly into the fluid circulation chamber 24 through the orifices 36.
- the pressure losses are thus reduced and the passage of the fluid is thus further facilitated, which tends to maintain or increase its flow.
- the second piston 30 is sensitive to the fluid flow and is capable of taking at least one low flow position and one high flow position.
- the hysteresis fluidic valve 10 comprises suitable means, here the second spring 28, for the piston 30 sensitive to the flow is in the high flow position when the fluid flow exceeds the predetermined threshold.
- the hysteresis fluidic valve 10 is intended to receive all types of fluid, namely a gas or a liquid.
- the hysteresis fluidic valve 10 is for receiving a liquid such as water.
- the hysteresis fluidic valve 10 When the fluid pressure is below a predetermined threshold, the hysteresis fluidic valve 10 is in its position shown in FIG. 2. The valve 26 is in the closed position, which has the consequence that the fluid flow rate is zero and that the second piston 30 is in the low flow position.
- the fluid pressure at the inlet of the hysteresis fluidic valve 10 is less than the predetermined threshold, the fluid can not reach the fluid outlet 14 of the hysteresis fluidic valve 10.
- the hysteresis fluidic valve 10 takes the position shown in FIG. Figure 3.
- the valve 26 is in the open position, but the piston 30 is still in the position low flow since the fluid does not circulate.
- the fluid occupies the fluid circulation chamber 24 but can not leave the hysteresis fluidic valve 10.
- the hysteresis fluid valve 10 assumes the position shown in FIG. 4.
- the valve 26 is in the open position and the second piston 30 is in the position high flow rate.
- the hysteresis fluidic valve 10 takes the position shown in FIG. 5.
- the second piston 30 is always in the high flow position because the fluid outlet 14 is open.
- the second piston 30 responsive to the fluid flow occupies part of the fluid circulation chamber 24, it gene the descent of the piston 30, the pin 16a can not enter sufficiently into said chamber 24.
- the second piston comprises a surface which forms a support for one end of the first piston 16, namely here the stud 16a, and the first piston 16 can not apply the seal 18 on the complementary end of the chamber. fluid circulation 24.
- the valve 26 is held in the open position.
- valve 26 and the piston 30 are thus arranged so that the piston
- valve 26 is prevented from occupying the closed position.
- the fluidic valve 10 is open as long as the fluid outlet 14 is not closed. This is why it can be qualified as a hysteresis 10 fluidic valve.
- An advantageous use of the valve according to the invention consists in placing at least two hysteresis fluidic valves on two parallel ducts fed by a main duct. Thanks to the two fluidic hysteresis valves, it is possible to prioritize the supply of one of the ducts. Indeed, by more or less tightening the knob 22, a higher or lower pressure threshold is defined and it is determined which of the two valves will open first.
- the piston 30 sensitive to the flow of the latter moves to the high flow position and thus prevents the valve 26 from occupying the closed position.
- the open hysteresis fluidic valve 10 will keep the pressure in the main duct at a low level. Therefore, the other hysteresis fluidic valve 10 can have its fluid outlet 14 which passes to the open position only when the first hysteresis fluidic valve 10 has closed its fluid outlet 14.
- FIG. 6 shows a hysteresis fluidic valve 100 according to a second embodiment. Only differences with the first mode will be described. Unchanged elements retain the same numeric references.
- the seal 18 has been replaced by a reinforced waterproof membrane 118.
- the piston 116 has a shape slightly different from that of the piston 16 but has the same functional parts. The same applies to the button 122.
- the means adapted for the valve to move from the closed position to the open position when the fluid pressure exceeds a predetermined threshold comprise the membrane 118, the piston 116 , the spring 20 and the button 122.
- the second piston 130 comprises a downstream section 134 whose diameter is greater than that of an upstream portion of the piston body 130.
- the clearance between the downstream portion 134 of the piston and the downstream section 12b of the inlet channel 112 is minimal.
- the clearance between the upstream portion of the piston 130 and the downstream section 12b of the inlet channel 12 is larger, which allows higher fluid flow rates.
- the piston 130 does not include orifices 36 for fluid circulation.
- the screwed button 122 and the chimney 111a comprise complementary stops respectively 122a and 111b so as to define a maximum pressure threshold, for example to preserve the integrity of the hysteresis fluidic valve 100. Indeed, when the complementary abutments 122a and 111b come into contact with each other, it is no longer possible to tighten the screwed knob 122 around the first spring 20.
- a connecting end 114a is arranged in the fluid outlet channel 114 of the body 111 in order, for example, to connect the hysteresis fluidic valve 100 to a suitable fluidic device (not shown).
- FIG. 7 shows a hysteresis fluidic control valve 200.
- the hysteresis fluidic control valve 200 comprises a fluidic control valve 202.
- This fluidic control valve 202 comprises a body 204 which here forms a main fluid conduit .
- the main fluid duct comprises an upstream duct 206 and a downstream duct 208.
- a tight membrane 210 is disposed between the duct upstream 206 and the downstream conduit 208.
- a spring 212 pushes the waterproof membrane resting on its seat.
- the fluidic control valve 202 comprises, disposed in parallel with the upstream duct 206, a duct 214 which leads to a chamber 216 defined by the leaktight membrane 210 and in which the spring 212 is disposed.
- the duct 214 is connected to a control output 218 of the fluidic control valve 202.
- the hysteresis fluidic valve 10 is connected to the control output 218 of the fluidic control valve 202.
- the hysteresis fluidic valve is subjected to the pressure of the fluid present in the upstream conduit 206, at least as long as the output of the hysteresis fluidic valve is closed.
- the adjustment of the cap of the fluidic valve with hysteresis must be such that the pressure of the fluid in the upstream conduit 206 is sufficient to open the valve of the latter.
- the drop in fluid pressure propagates to the chamber 216.
- the fluid coming from the upstream duct 206 can therefore join the downstream duct 208.
- the circulation of fluid in the fluidic control valve 202 depends on the fluid flow in the hysteresis fluidic valve 10.
- FIG. 8 schematically shows a hysteresis fluidic control 300.
- the hysteresis fluidic control 300 comprises the hysteresis fluidic valve 10 as previously described and a fluidic control 302 connected to the fluid outlet 14 of the Hysteresis fluidic valve 10.
- the fluidic control 302 is a valve.
- the fluidic control 302 is an autonomous watering control device that is able to open and close when the device calculates that it is necessary to proceed with a watering.
- a hysteresis fluidic valve 10 is used which is part of both a hysteresis fluidic control 300 as previously described and a hysteresis fluidic control valve 200 also such that previously described.
