  • connection end of the supply head can be automatically aligned with the filling / emptying end of the valve.
  • the longitudinal axis of the connection end piece of the gas supply head coincides with the longitudinal axis of the end piece filling / emptying the tap.
  • the anvils are located at the lower end of two vertical arms integral with two movable horizontal guide members in the opposite direction in two elongated openings in the carriage, perpendicular to the opposite directions of movement of the latter.
  • the horizontal guide members each carry a flange advancing above the table and are movable under the control of at least one cylinder and at least one tension spring connecting the flanges, the cylinder and the spring being perpendicular to the opposite directions of movement of the carriage.
  • anvils are permanently urged towards each other by the tension spring (s) and that they exert additional pressure on the square base when they are tightened, which eliminates the risks so that the latter may inadvertently escape their grip, in particular during a failure of the jack (s).
  • the gas supply head comprises a body extending vertically and is symmetrical relative to the vertical plane containing the pivot axis of the table and extending parallel to the opposite directions of movement of the carriage.
  • the horizontal base and the carriage each carry a flange advancing above the table, the flanges being connected by at least one jack and at least one tension spring extending parallel to the opposite directions of movement of the carriage .
  • the connecting end piece is permanently biased towards the tap by the tension spring (s) and that it exerts additional pressure on the filling / emptying end piece when it is applied against it, which maintains a tight connection between the two end pieces in the event of failure of the jack (s).
  • the screwing / unscrewing bell is mounted at the lower end of a vertical rod passing through orifices made in the table and the carriage and whose longitudinal axis coincides with the pivot axis of Table.

  • a liquefied gas in particular butane or propane
  • the frame 5 is slidably mounted on two vertical columns (see Figures 3 and 4) secured to a fixed support not shown and is movable along these columns under the control of a jack also not shown, or a member equivalent.
  • the table 6 is suspended from the frame 5 by means of a hollow column 16 extending vertically.
  • the column 16 is fixed to the table 6 in the vicinity of its lower end and is mounted for rotation in a horizontal bearing 17 (see FIG. 3) mounted on the frame 5, in the vicinity of its upper end.
  • the anvils 10 are directed towards each other and intended to come into engagement with the valve 1 of the bottle to be filled, at the level of the square base 2 and of an area of the body of the valve diametrically opposite to the filling nozzle 4.
  • the anvils 10 each comprise a first active surface 18, a second active surface 19a and a third active surface 19b, the second and third active surfaces of each anvil projecting from the first active surface to which they are associated, in the vicinity of the upper corner thereof which is furthest from the gas supply head 12.
  • the first active surfaces 18 are planar, extend vertically and are intended to cooperate with the two sides of the square base 2 of the valve which are parallel to the nozzle 4 thereof.
  • the second active surfaces 19a are planar, extend horizontally and are intended to cooperate with the upper face of the base 2.
  • the third active surfaces 19b consist of sections of vertical cylinders whose radius corresponds to that of the valve body and are intended to cooperate with the zone of the valve which is diametrically opposite to the filling / emptying nozzle 4.
  • the anvils 10 are located at the lower end of two vertical arms 20 integral with two horizontal guide members 21 carried by the carriage 8.
  • the guide members 21 are retained in two elongated openings 22 formed in the carriage and in which they can be moved in the opposite direction in the directions of movement 11 and therefore perpendicular to the directions of movement 9 of the carriage 8.
  • tension spring 25 permanently biases the flanges 23 towards one another. Consequently, if the actuator 24 fails while the jaws 10 are applied against the base 2 of the valve, the spring 25 will keep these jaws tight and prevent the base from escaping from them.
  • the plane of symmetry P1 of the anvils 10 forms an angle a with the vertical plane P2 containing the longitudinal axis of the filling / emptying nozzle 4 of the valve.
  • the gas filling head 12 comprises a vertical body symmetrical with respect to the plane P1 and is integral with a base 26 carried by the table 6.
  • the base 26 is movable on the table 6 in the directions of movement 9 of the carriage 8, and carries a flange 27 advancing above the table 6.
  • the flange 27 is parallel to a flange 28 provided on the carriage 8 and is located on the same side as the flange 28 relative to the pivot axis 7 of the table.
  • the flanges 27 and 28 are connected by a jack 29 arranged parallel to the directions of movement 9 and two tension springs 30 extending parallel to the jack 29, on either side of the latter.
  • the connecting end piece 13 of the latter comes close to the end piece 4 of the valve when the piston rod of the jack 29 retracts into the cylinder thereof and moves away from the end piece 4 when the piston rod of the jack 29 extends.
  • the two springs 30 permanently urge the feed head 2 towards the valve. Consequently, if the cylinder 29 has a failure while the end pieces 13 and 4 are connected, the springs 30 will hold these end pieces against each other and prevent the risk of gas leakage between them.
  • the screwing / unscrewing bell 14 is mounted at the lower end of a vertical rod 31 passing through orifices 32,33 (visible in FIGS. 3 and 4) formed respectively in the table 6 and in the carriage 8, l orifice 32 being circular while orifice 33 is oblong so that the carriage can move in opposite directions 9.
