  • the piston ( 73 ) is essentially constituted by a full radial wall ( 731 ) (thus, without a passage opening, contrary to the valve of EP 1 099 647 A1), fixed on a cylindrical ring ( 732 ), the spring ( 74 ) penetrating into this cylindrical ring to bear on the lower face of the radial wall, or in the case shown here, on radial ribs ( 733 ) which are shorter than the cylindrical ring ( 732 ) and extend from the radial wall.
  • a shoulder ( 734 ) formed on the outer face of the cylindrical ring ( 732 ) provides sealing between the piston ( 73 ) and the inner face of the cylindrical wall ( 721 ) of the bottom ( 72 ) of the metering chamber. The air contained inside the bottom ( 72 ) below the piston ( 73 ) is compressed when the chamber fills up.
  • valve seal ( 5 a ), of annular shape, is placed in the bottom of the dome, between the latter and the top face of the valve body.
  • the chamber seal ( 5 b ) is placed inside the axial channel ( 95 ) of the valve body and it bears on the upper face of the first set of ribs ( 96 ). It is held in this position by the spacer ( 3 ).
  • the chamber seal ( 5 b ) has an annular shape. Its outer diameter corresponds to the inner diameter of the axial channel ( 95 ) above the first set of ribs ( 96 ). Its inner diameter corresponds to the outer diameter of the stem ( 4 ) at the first radial holes ( 45 ) and second radial holes ( 443 ).
  • the chamber seal ( 5 b ) On its inner face, the chamber seal ( 5 b ) has two parallel radial grooves ( 51 b , 52 b ) located one above the other.
  • the height of the lower groove ( 51 b ) is greater than or equal to the axial distance separating the first radial holes ( 45 ) from the second radial holes ( 443 ) of the stem.
  • the metering chamber ( 7 ) fixed on the lower section of the valve body ( 9 ).
  • the stem ( 4 ) is located within the valve body ( 9 ), pushed back into the upper position by a spring ( 8 ) which is supported on one side on the shoulder ( 441 ) of the stem ( 4 ) and on the other on the upper face of the collar ( 98 ).
  • the chamber seal ( 5 b ) is blocked within the axial channel ( 95 ) between the top of the ribs of the first set ( 96 ) and the spacer ( 3 ) which is itself placed in the top part of the axial channel ( 95 ).
  • the upper ring ( 91 ) of the valve body is secured to the cup ( 2 ), for example, by crimping with interposition of the valve seal ( 5 a ) which surrounds the upper section of the stem ( 4 ). This seal ensure in particular sealing between the area located below it and that located above it.
  • an inlet passage and an outlet passage are provided, inlet closure means and outlet closure means being respectively provided in the input path and the output path for closing these passages when necessary.
  • the inlet passage is constituted by the inlet orifices ( 99 ) made in the valve body, the orifice formed by the funnel-shaped portion ( 981 ) of the collar ( 98 ) of the valve body and the second cylindrical wall ( 714 ), then the orifice ( 712 ) of the cover ( 71 ) of the metering chamber.
  • the inlet passage is clearly visible for example in FIG. 3 b , where it is indicated by an arrow.
  • the closure means of this inlet passage are constituted by the tenon-shaped lower end of the second cylindrical wall ( 44 ) of the stem which, when the stem ( 4 ) is sufficiently lowered, comes to sealingly close the opening of the funnel-shaped portion ( 981 ) of the valve body and the annular ring ( 717 ).
  • the closure of the inlet passage by the closure means input is clearly visible in FIGS. 4 b and 5 b .
  • the outlet passage is constituted by the orifice formed by the orifice ( 712 ) of the cover ( 71 ) of the metering chamber, the second cylindrical wall ( 714 ), the funnel-shaped portion ( 981 ) of the collar ( 98 ) of the valve body, the lower central channel ( 442 ) of the stem, the second set of radial holes ( 443 ), the first annular groove ( 51 b ) of the chamber seal ( 5 b ), the first set of radial holes ( 45 ) and the upper central channel ( 42 ).
  • the outlet passage is clearly visible in FIG. 4 b where it is marked by an arrow.
  • the closure means of the outlet passage are constituted by the inner face of the cylindrical wall of the chamber seal ( 5 b ) which, as soon as the two sets of radial holes ( 45 , 443 ) are no longer aligned with the first annular groove ( 51 b ), constitutes a tight barrier between these two sets of holes, thereby closing the outlet passage.
  • the closure of the outlet passage is clearly visible in FIGS. 3 b and 5 b.
  • the radial holes ( 48 ) of the third cylindrical wall ( 46 ) of the stem are located above the valve seal ( 5 a ), that is to say outside the valve.
  • the radial holes ( 45 ) located at the bottom of the upper central channel ( 42 ) are located facing the upper groove ( 52 b ) of the chamber seal ( 5 b ) (or against the wall of the chamber seal which closes it if there is no second annular groove), while the second radial holes ( 443 ) are located facing the lower groove ( 51 b ).
  • the two sets of radial holes are isolated from each other and there is no communication between the lower central channel ( 442 ) and the upper central channel ( 42 ) of the stem ( 4 ).
  • the tenon ( 44 ) of the stem penetrates into the orifice of the collar ( 98 ) but without coming into contact with the bottom of the funnel-shaped portion ( 981 ) and with the annular ring ( 717 ).
  • the passage between the inside of the pouch ( 11 ) and the metering chamber is thus free.
  • This passage proceeds through the radial holes ( 99 ), called inlet orifices, then the space located between the funnel-shaped portion ( 981 ) of the collar ( 98 ) and the lower end of the tenon ( 44 ), and finally the central orifice ( 712 ) of the cover of the metering chamber.
  • the product goes up the lower axial channel ( 442 ) of the stem and fills the lower section of the valve body. However, it is blocked in the valve body by the chamber seal ( 5 b ) and at the stem inside the bottom groove ( 51 b ) of the chamber seal. The product cannot get out of the valve, but the metering chamber is filled.
  • the valve When the valve is actuated, that is to say a pressure is exerted on the top portion of the stem, the latter moves downwards.
  • the stem To empty the metering chamber, the stem is designed to be lowered into an intermediate position between the high or closure position, and the low or short-circuit position.
  • the stem is lowered so that the radial holes ( 48 ) of the third cylindrical wall of the stem are again located above the valve seal ( 5 a ).
  • the radial holes ( 45 ) located in the lower portion of the upper central channel ( 42 ) of the stem like the radial holes ( 443 ) located in the upper portion of the lower central channel ( 442 ), are situated facing the lower annular groove ( 51 b ): they are thus in communication with each other.
  • the lower end of the tenon ( 44 ) now enters the funnel-shaped portion ( 981 ) of the collar and thus sealingly closes the central orifice of the collar.
  • the product can no longer go from the pouch (or vial) into the metering chamber since the inlet passage between the inlet radial holes ( 99 ) and the metering chamber is closed by the sealed closure of the central hole of the collar by the tenon ( 44 ).
  • the metering chamber being in contact with the outside, the pressure drops and the spring ( 74 ) pushes the piston ( 73 ) back to the upper portion of the metering chamber. The product is thus expelled.
  • the product contained in the pouch can enter the side channels ( 931 ) of the fins ( 93 ) of the valve body and go through their orifices ( 94 ) to penetrate into the space located between the valve seal ( 5 a ) and the chamber seal ( 5 b ). However, this space is sealingly closed and the product contained therein cannot escape.
  • the radial holes ( 48 ) of the third cylindrical wall ( 46 ) of the stem pass below the valve seal ( 5 a ), so they are in contact with the inside of the valve body.
  • the radial holes ( 45 ) are facing the lower groove ( 51 b ) of the chamber seal, while the radial holes ( 443 ) are located in the vicinity of the first and second set of ribs ( 96 , 97 ).
  • the upper central channel ( 42 ) and the lower central channel ( 442 ) are again isolated from each other.
  • the tenon ( 44 ) penetrates even more into the funnel-shaped portion of the collar ( 98 ), maintaining the sealed closure of the central hole of the collar.
  • the inlet and outlet passages are closed and the metering chamber is not only isolated from the pouch ( 11 ), but it is also isolated from the outside: it can neither be filled nor emptied. On the contrary, the product contained in the pouch (or vial) escapes through the valve via the side channels of the fins.
  • the short-circuit position is not necessary, it is possible to dispense with the third cylindrical wall ( 46 ) of the stem and the side channels ( 931 ) of the valve body, even if the fins can be retained to facilitate welding of the pouch ( 11 ).
  • the stem then moves only between the high closure position and the intermediate opening position, which then becomes the second end position.
  • the pouch is not essential either. It is possible to remove the product directly from the vial. As such, the valve can be used upside down (valve placed below the vial).
  • a plunger tube connected to the radial openings ( 99 ) of the lower section of the valve body and the side channels ( 931 ) of the fins must be provided.
  • the radial holes ( 45 , 443 , 48 , 99 ) are provided in pairs. Of course, it would be possible to have only one each time, or on the contrary, more than two.
  • the metering valve of the invention can be used in any position.
  • the presence of the spring ( 74 ) constraining the piston ( 73 ) ensures a fast and full exit of the product out of the metering chamber. Since the metering chamber is filled from the top, via the path that the product uses to exit, it is not at risk of being emptied between uses, even when one dispenses with using a pouch.
