  • the valve disposed at the outlet of the chamber (2) of liquid comprises elastic means for holding in the closed position, making it possible to close sealing the outlet opening (25) of the chamber (2) of liquid until the pressure in the chamber (2) of liquid is insufficient so that the liquid contained in the chamber (2) of liquid does not push the valve of seal.
  • the sealing valve as represented in FIG. 2, is produced, in a nonlimiting manner, by a ball (412) pushed by a resilient element (413, 415) against a frustoconical wall (411) widening toward the ball (412).
