• Figure 1 illustrates a gas cylinder valve, according to the invention.
• the valve 2 comprises a body 4, preferably generally solid.
• the body 4 comprises a connection connection 6 to a gas cylinder (not shown). This fitting is in the form of conical thread and corresponds to an inlet 7 of the valve.
• the body 4 also includes a gas outlet 9.
• the valve is provided with a steering wheel 8 disposed laterally on the body 4. This flywheel 8 is a control wheel of a residual pressure holding device and a valve valve.
• FIG. 2 which is a sectional view along the axis 2-2 of Figure 1, illustrates the interior of the upper part of the valve.
• the body encloses a valve 14 for closing the passage 10 connecting the gas inlet (FIG. 7) with the outlet 9.
• the body comprises a chamber 22 connected to the inlet 7 (FIG. figurel) via a residual pressure maintaining device (FIG. 3, reference 38).
• the chamber contains a shutter 16 held in pressure against a seat 18 by a spring 20.
• the spring 20 bears on the bottom of the chamber 22.
• the seat 18 consists of a pellet with a central hole, made of material suitable for ensure sealing with the shutter 16.
• the latter may be of metal material and the seat may be of plastic material such as for example nylon.
• the seat 18 is sandwiched between a shoulder formed in the body 4 of the valve and a seat support 26 held in pressure against the shoulder by a clamping piece 30 screwed into a cavity of the body 4.
• a seal 28 as well as optionally an anti-extrusion ring are provided between the seat support 26 and its housing in the body 4. This is a static seal since the seat support 26 is stationary.
• the seat support 26 includes a central bore extending along its main axis. This bore accommodates a control rod 12 of the shutter 16 of the valve 14.
• the control rod 12 comprises a groove with a seal 24 and optionally an anti-extrusion ring so as to seal with the bore of the seat support 26 in which she is lodged.
• the seal is dynamic because the control rod is able to move in translation along its main axis. It also comprises a shoulder intended to bear against a corresponding shoulder of the clamping piece 30. A first end (left according to FIG. 2) is in front of the shutter 16 and a second end (on the right according to FIG. 2) leaves the body 4 of the valve and cooperates with a profiled surface of the steering wheel 8.
• the valve 14 is configured so that the shutter 16 is disposed on the upstream side of the seat 18 and the spring 20 maintains it normally in pressure against the seat 18. In this way, the valve closes naturally and the pressure of the bottle also exerts pressure on the shutter 16 facing the seat 18. As will be explained in more detail in connection with the 3 and 4, the rotation of the wheel 8 to open the valve 14 will move the control rod 12 to the shutter 16 so as to move it away from its seat 18 and allow the passage of gas from the chamber 22 to the output 9.
• the control rod 12 In the closed position of the valve, corresponding to that illustrated in Figure 2, the control rod 12 is not pressurized between the contoured surface of the wheel 8 and the front face of the shutter 16 , so as to ensure a satisfactory seal and to allow a matting or tamping of the seat according to the pressure exerted and according to the number of cycles and / or the age of the valve.
• the control rod 12 in the closed position of the valve 14, has at least one of its ends at a distance from its respective contact surface according to a suitable mechanical clearance.
• FIG 3 which is a longitudinal sectional view of the valve of Figure 1, illustrates the interior of the valve.
• the passage 10 made in the body 4 connects the input 7 to the output (not visible in this figure but in Figure 2, reference 9).
• the passage opening towards the top of the valve body is in direct communication with the chamber containing the valve 14. It may be intended to be connected to a manometer. It should be noted that the tap illustrated in Figures 1 to 3 is incomplete at its upper part.
• the body 4 encloses a residual pressure holding device 38 in the bottle.
• the latter is disposed at the passage 10 connecting the inlet 7 to the valve outlet, upstream of the valve 14.
• It essentially comprises a shutter 43 cooperating with a seat 41, similarly to the valve 14, but with the important difference that the shutter defines a first variable volume chamber 39 upstream of the seat 41.
• the shutter 43 in fact comprises a first portion 44 cooperating with the seat 41 of the body 4 of the valve, and a second portion 42 sealingly sliding with a wall of the body 4. This wall may be formed by a part 40 attached in a body bore, as shown in FIG. 3.
• the second portion 43 has a section greater than that of the first portion 44, which makes it possible, when applying the pressure coming from the bottle, to generate a resultant force on the shutter 43 directed to the second portion.
• This force is opposed to the force of the spring or springs 46 arranged between the screwed piece 40 and the face of the shutter 43 corresponding to the second portion.
• the elastic force of the springs 46 and the sectional difference between the second and first portions are dimensioned so as to allow movement of the shutter and hence the opening of the gas passage from a given pressure.
• This minimum pressure for the opening of the residual pressure maintaining device may be of the order of a few bars, such as 3 bars. This pressure corresponds to the residual pressure that will be in the bottle when the contents of the latter have been consumed and that it will no longer deliver gas.
• a channel 45 formed in the shutter 43 connects a second chamber 39 with the gas passage 10 directly downstream of the shutter 43.
• the second chamber 39 is defined by the housing of the shutter 43 and its rear face corresponding to its second portion 42. If one tries to fill the bottle without first opening the residual pressure maintaining device, the filling pressure will be established in the chamber 39 which has an effective section corresponding to the second portion of the shutter, this section being greater than that of the first portion. This then results in a force on the shutter directed in the closing direction of the latter.
• a control rod 36 is partially disposed in the gas passage 10 directly downstream of the seat 41 and the shutter 43 of the residual pressure holding device 38.
• This control rod is similar to the control rod 12 of the valve 14. It is slidably mounted in a bore of the body 4, parallel to the control rod 12. It also has a shoulder intended to cooperate with a corresponding shoulder of the body 4, so as to limit its displacement in the direction of closure of the residual pressure maintaining device 38.
• a spring is further provided to assist the movement of the rod 36 towards the flywheel 8.
• Means such as a seal possibly accompanied by an anti-extrusion ring, are provided in a groove of the control rod 36, so as to ensure a seal with the bore of the body 4.
• a first end of the rod of control is vis-à-vis the first portion 44 of the shutter 43 and a second end is in contact with a profile surface of the flywheel 8. Similar to the valve 14, the control rod is sized to be able to work correctly the residual pressure maintenance device, despite any matting of the contact surfaces between the seat 41 and the shutter 43. To do this, a mechanical play is provided between the first end (the left one according to Figure 3 ) of the control rod 36 and the shutter 43 when the steering wheel is in a position not acting on the residual pressure maintenance device.
• the mechanical clearance may be between 0.1 mm and 2 mm, preferably between 0.1 and 1 mm, more preferably between 0.1 and 0.5 mm.
• the flywheel 8 comprises a main disk-shaped part and a skirt formed by a series of sections 32 and 48, some of which are provided with a portion of hook shape intended to cooperate with a groove 34 (FIG. 3) formed on the body 2.
• a first track 50 is intended to cooperate with the control rod 36 of the residual pressure maintenance device. It comprises a sliding surface for the corresponding end of the control rod, this sliding surface having a profile inclined so as to move the control rod during the rotation of the flywheel 8.
• the first track 50 comprises two recesses or points rest for the corresponding end of the control rod.
• a first recess 52 corresponds to a first position of the control rod where it does not control the residual pressure maintenance device.
• This first hollow corresponds to a portion of the track where its profile is the lowest or remote from the body of the valve.
• a second hollow 54 corresponds to a second position of the control rod where it forces the opening of the residual pressure maintenance device.
• the second hollow corresponds to a portion of the track where its profile is the highest or closest to the body of the valve.
• the first track also comprises a clearance zone 56 extending the track from the first recess 52. This clearance zone is designed not to move the corresponding control rod.
• a second track 58 is intended to cooperate with the control rod 12 of the valve 14.
• the second track comprises a sliding surface for the corresponding end of the control rod, this surface of sliding having an inclined profile so as to move the control rod during the rotation of the wheel 8. It comprises three recesses or rest points for the corresponding end of the control rod.
• a first hollow 64 disposed at a central portion of the track forming a lower portion of the track. The first depression corresponds to a position of the steering wheel where the valve is not controlled, that is to say is normally closed.
• a second recess 60 and a third recess 62 are arranged, respectively, at the ends of the track 58. These ends correspond to high or near portions of the valve body.
• the second and third hollows correspond to positions of the steering wheel where the valve is actuated, that is to say is put in the open state.
• the first recess 52 of the first track 50 and the first recess 64 of the second track correspond to a closed position of the valve, that is to say a position where the valve and the residual pressure maintaining device are normally closed.
• the control rods 12 and 36 are diametrically opposed relative to the center of rotation of the wheel 8, so that the first recesses 52 and 64 of the first and second tracks are also diametrically opposed. .
• the second recess 54 of the first track 50 and the third recess 62 of the second track 58 correspond to a filling position of the bottle.
• the second recess 54 of the first track 50 makes it possible to force the opening of the residual pressure-maintaining device and the third recess 62 of the second track 58 ensures the opening of the valve 14.
• the opening of the valve 14 is in principle not necessary given its construction in the form of a valve which can open naturally under the filling pressure.
• the closing spring 20 of the shutter 16 of the valve 14 is quite powerful, in particular to ensure a satisfactory level of safety and sealing for the valve.
• the pressure and, consequently, the flow rate resulting from the gas at the outlet of the valve during filling could be greatly reduced when the valve 14 passes in the absence of forced opening thereof. This is the reason why an opening of the valve 14 is provided during the filling of the bottle.
• the second recess 60 of the second track 58 and the clearance zone 56 of the first track 50 correspond to a service position of the valve. Indeed, the second recess 60 provides a displacement of the control rod of the valve forcing its opening while the clearance zone 56 of the first track 50 ensures undisturbed operation of the residual pressure maintenance device.
