  • the notches 5 and 6 are in alignment with the spigots 3 and 4 respectively.
  • Axial passages 7 and 8 extend through the spigots 3 and 4 through the wall of the cup 1 so as to connect the spigots to the notches 5 and 6.
  • At the top of the cup 1 is an external shoulder 9.
  • the bottom of the cup is axially pierced by a hole 1a.
  • a slidable sealing member 40 Inside the central chamber 2 is a slidable sealing member 40.
  • This sealing member 40 is cylindrical in shape and comprises a cylindrical sidewall 40a and a bottom 40b. In the middle of the bottom is a bore 41 the peripheral walls of which are provided with grooves 42 parallel to the axis of the slidable sealing member 40.
  • the slidable sealing member 40 has an internal substantially cylindrical recess 43. Near its top is an external shoulder 44 on which the sealing member 40 slides. The outer diameter of the shoulder 44 is equal to the inner diameter of the central chamber 2 in the cylindrical cup 1.
  • the spout 45 extends along the longitudinal axis of the sliding sealing member 40.
  • the spout 45 is provided with a central passageway 450 closed at its lower end by a bottom 45b.
  • An intermediate portion of this spout carries an external circular shoulder 15.
  • the external diameter of the shoulder 15 is slightly less than the diameter of the recess 43.
  • the diameter of the lower part of the spout between the bottom 45 and the shoulder 15 is equal to the inner diameter in the bore 41 taken between the grooves.
  • At the base of the spout 45 is a cup 46 in which the lower part of the spout 45 is seated.
  • the cup 46 has an upper lip 47.
  • the surface of the lip 47 that is to say the surface facing the sliding sealing member 40, is provided with ridges 47a separated from each other by radial grooves which extend from the edge of the lip 47 to the central part of the cup 46, in which the lower end of the spout is seated.
  • a spring 12 is positioned between the bottom of the central chamber 2 and the lip 47 of the cup 46. Above the circular shoulder 15 the spout 45 is pierced by a hole 16 which passes through the wall of the spout.
  • An annular sealing member 36 is positioned at the top of the valve.
  • This sealing member has an external diameter equal to the external diameter of the shoulder 9 and an internal diameter equal to the external diameter of the upper part of the spout 45. In the closed position shown on FIG. 1, this sealing member bears on the upper surfaces of the outer cup 1 and the sliding sealing member 40.
  • the annular sealing member 36 is positioned on the cup 1, the notches 5 and 6 at the top of this cup are converted into holes.
  • the annular sealing member 36 and cup 1 are held together by a metallic cap 19 which grips the circular sealing member 36 and the shoulder 9 of the cup 1. It is obvious that the cap 19 has an opening 20 in its central part which permits the free passage of the spout 45.
  • the central part of the circular sealing member 36 forms a cup 360 which is positioned inside the hole 20 in the cap 19.
  • the cap 19 is adapted to be fastened to the top of an outer container which container may hold flexible inner containers in which the two products to be dispensed are stored, as well as the pressurizing fluid which places the products in these flexible containers under pressure.
  • Suitable pressurizing fluids include the conventional freons.
  • the upper parts of the flexible containers holding the products to be dispensed comprise tubes 21 and 22, which tubes are adapted to be respectively mounted on the spigots 3 and 4.
  • this container holds, connected to the dispensing valve, the flexible containers filled with the products to be dispensed.
  • the freon is then introduced into the outer container by any suitable means, and in particular through a special valve, or directly through the valve according to the invention when placed in the position shown in FIG. 2.
  • the freon introduced through the axial passageway 45a in the spout 45 passes through the hole 16 which is then located between the circular sealing member 36 and the sliding sealing member 40.
  • the freon which passes through the recess 43 along the axis of the sliding sealing member 40 enters the grooves between the ridges 42 and then the grooves between the ridges 47a. It thus enters the central chamber 2, passes through the orifice la, and reaches the interior of the outer container, which is to be placed under pressure.
  • valve according to the invention When the user desires to employ the valve according to the invention, he presses the spout 45 down along the axis thereof. The spring 12 is compressed and permits the spout 45 to be forced down into the outer cylindrical cup 1 of the valve.
  • the first step in this depression is shown in FIG. 2. It will be seen that the hole 16 has passed to the inside of the recess 43. It follows that there is communication between the exterior and the interior of the outer container which results in a jet of pressurizing gas through the seat 43, the hole 16 and the central passageway 45a. This jet of pressurizing gas cleans the recess 43, in which particles of products to be dispensed may have remained from a previous dispensing operation. It will thus be appreciated that the valve according to the invention is of the self-cleaning type.
  • valve for dispensing at least one fluid which is stored under pressure, said valve comprising:
  • a cup defining a central chamber having an opening in its bottom and at least one passageway leading to the exterior of said cup from a port opening into the upper part of said chamber,
