- the filling plug 100 may comprise a cylindrical body 1, one of the ends of which has a connection 2 allowing the connection of sealing said socket 100 to a flexible 121 of a gas conditioning ramp (see Figure 12).
- the other end of the socket 100 includes a connection interface housing a fluid distribution axis 13.
- the connection interface comprises a mechanical attachment system 4 allowing a tight coupling to the port of the valve 6 of the tank to be filled.
- the attachment system 4 comprises bent grooves 41 formed on the end of the socket 100 intended to cooperate with radial pins 61 formed on one end of the valve 6.
- the assembly forms a bayonet type fastening system.
- this embodiment of the attachment is neither exclusive nor limiting and can be replaced or supplemented by other equivalent connection systems such as screwing, clipping, clamping, etc ....
- the bayonet connection 41-61 can be locked by a movable member.
- the locking / unlocking of the attachment of the axes in the grooves 41 can be provided in particular by a ring 5 of generally tubular shape mounted to move in translation co-axially to the body 1 of the socket.
- the locking / unlocking ring 5 is urged by an internal spring 52 towards an advanced position in which it closes the open ends (outlets) of the grooves 41. This prevents the lugs 61 out of the grooves 41 corresponding (locking the tap on the valve 6).
- the ring 5 can be pushed manually and / or mechanically backwards (against the action of the spring 52) to release the open ends (outlets) of the grooves 41 (unlocking the plug of the valve 6).
- the locking position can be locked via a latch system 51, 83, 8 described in more detail below.
- the filling plug is in the so-called rest position (no gas under pressure in the socket).
- a connector 2 for example female, is provided at the rear end of the socket 100.
- the connector 2 is formed for example in a tubular support axis 12.
- This connection 2 for a hose may comprise a tapping 21 and a female sealing cone 22 allowing a sealing connection of the filling plug 100 with a hose of a high pressure filling rail (not shown).
- the body 1 of the filling socket 100 comprises an external handle 1 1.
- the handle 1 1 is free to rotate about the support axis 12 to prevent transmission of a torsion torque to the hose 121 which is connected to the rear of the socket.
- the handle 1 1 gripping is rotationally secured to a lock ring 51 described in more detail below (the locking ring 51 can however slide relative to the handle 1 1 when it is not blocked as described below).
- the support shaft 12 houses in its center a tubular distribution axis 13 having an internal conduit for conveying the fluid under pressure.
- a sealing plug 3 is mounted on the end in the coupling 42. Specifically, the shutter 3 is slidably mounted on the front end of the distribution axis 13.
- the shutter 3 covers the end of the axis 13 distribution.
- the shutter 3 comprises, for example, two sealing torques 31 each comprising an O-ring and an anti-extrusion ring positioned on either side of the distribution ports 131 of the axis 13. These two sealing torques 31 isolate the circuit 122 of the filling plug 100 vis-à-vis the outside.
- the shutter 3 is for example pushed back by contact with a mating surface of the valve port 6. More precisely, the shutter 3 can slide around the axis 13 distribution and can be pushed backwards in a position clearing the orifices 131.
- a return spring 33 preferably solves by default the shutter forward in the closed position of the orifices 131 (automatic closure in case of disconnection).
- the locking / unlocking mobile ring 5 slides around a coupling 42 mounted on the support shaft 12.

A translation then a rotation of the filling plug 100 causes, once the bayonets 61 in contact with the locking ring 5, the recoil of this movable ring 5. When the pins 61 are at the end of the grooves 41, the ring 5 lock automatically returns to its locked position (spring 52) in which it locks the bayonets 61 in housing 53 (see Figure 7).
- the end of the distribution pin 13 enters the body of the valve 6 via an opening (see FIGS. 8 and 9) by disengaging the shutter 3.

- the two sealing couples 62 and 63 are arranged concentrically at the end of the axis 13 and channel the fluid that radially out of the axis 13 through orifices 64 (see Figure 8).
- the two sealing couples 62 and 63 preferably have the same diameters so that the forces due to the pressure of the gas on the axis are balanced. In this way, the mechanical stresses on the connection between the plug 100 and the valve 6 are weak.
- the support shaft 12 also houses a tubular piston 8 biased forward by a spring 81.
- the piston 8 is for example of the differential type and has two ends of sections S1 and S2 different sized to generate on the piston 8 an opposing effort the action of the spring 81 when pressurized gas arrives through the rear connector 2 (see Figures 9 and 10). In the configuration of Figure 9, the piston 8 is not biased by the gas pressure (unlocked configuration).
- the piston 8 moves backwards (see FIG. 10, blocking configuration) by surpassing the force F of the spring 81.
- the piston 8 comprises an inclined plane 82 or any other appropriate cam surface in contact with one or more pins 83.
- the pins 83 are movably mounted in a slot formed in the axis 12 support.
- the lights housing the pins 83 open into a groove 59 opposite a surface of a lock ring 51.
- the lock ring 51 is mounted around the support shaft 12 and is integral in translation with the locking ring 5.
- the pins 83 have a length dimensioned to allow them to protrude into the groove 59 when the piston 8 has reached its limit position (see Figure 10).
- the length L of a pin 83 can be defined as follows:
- L12 thickness of the wall of the axis 12 support
- L ⁇ (L12 thickness of the wall of the axis 12 support +
- L8 height of the inclined plane).
- the pins 83 protrude into the groove 59 of the locking ring 51, they form stops preventing the translation of the locking ring 51 along the axis 12.
- the pins 83 projecting into the groove 59 form a mechanical key-type connection between the fixed support shaft 12 and the mobile latch ring 51.
- the lock ring 51 thus blocks the translation of the movable ring 5 (the lock ring 51 is integral in translation with the locking ring 5). In this way, the bayonets 61 of the valve 6 can no longer be released from their housings 53.
- the uncoupling of the filling plug 100 with respect to the valve 6 is made impossible.
- the uncoupling of the filling plug 100 with respect to the valve 6 will only be possible again when the pressure in the filling plug 100 is lower than the threshold pressure Ps (the reverse process to that described above) cf. figure 12.
- the unlocking of the socket 100 can be obtained by manually or mechanically pushing the ring 5 rearward to allow to undo the bayonet catch (or equivalent).
- a filling ramp can be equipped with several filling plugs 100.
- the filling pressure arrives in the filling plug 100 which is closed and sealed (shutter 3).
- the locking system 5 is locked in the locking position which prohibits the locking. coupling of said filling plug 100 to a valve 6.
- FIG 3 shows a possible variant of the filling plug 100 of FIGS. 1 and 2 in which the grip body 100 is provided with a fixed grip wheel 11 enabling improve the handling of the socket 100 by the operator.
- the unlocking command of said filling plug is embodied by a movable wheel 51 located coaxially and recessed relative to the fixed steering wheel 11.
- the invention also allows a balancing of the forces resulting from the pressure of the gas, which has the effect of limiting the repulsive forces of the filling plug and thus the mechanical stresses on the connection between the connector 6 and the filling plug 100 .
