- the dispensing nozzle 2 extending in a vertical direction Z and is terminated by a lower end 2a.
- the dispensing nozzle 2 comprises a central channel 4.
- the central channel 4 extends in the vertical direction Z and is terminated by a dispensing opening 4a at the lower end 2a of the dispensing nozzle 2.
- the dispensing nozzle 2 may have a form of revolution, for example cylindrical, and may be mounted on a frame by shrinking or screwing, for example a frame accommodating a plurality of distribution nozzles 2.
- the device 1 comprises a product inlet duct 5.
- the product inlet duct 5 may be an integral part of the dispensing nozzle 2 or may be formed by an additional part fixed on the dispensing nozzle 2.
- the product inlet duct 5 is in communication with the central duct 4 of the distribution nozzle via an inlet opening 4b of the central duct 4.
- a distribution portion 4c of the central channel 4 is thus defined between the inlet opening 4b and the dispensing opening 4a.
- the shutter rod 3 extends substantially in the vertical direction Z and is terminated by a lower end 3a.
- the shutter rod 3 is at least partially accommodated in the central channel 4 of the dispensing nozzle 2.
- the shutter rod 3 is able to move in the vertical direction Z in the central channel 4, for example by sliding.
- the shutter rod 3 may for example be centered and held in the dispensing nozzle by guide orifices arranged in the central channel 4.
- the shutter rod 3 is able to move in the vertical direction Z between an open position, a closed position and a contact position.
- the shutter rod 3 may also be adapted to move into a release position, said release position may be identical to the closed position, as described below.
- the open, closed, contact and release positions of the sealing rod 3 are successively illustrated for example in FIGS. 1, 3, 5 and 7.
- These positions of the shutter rod 3 may in particular be ordered from top to bottom in the following manner: open position and closed position and release position, then contact position. In this way, in the open position the shutter rod is in its highest position, and in the contact position, the shutter rod is in its lowest position.
- the closed and release positions are therefore intermediate positions between the open position and the contact position, where appropriate identical intermediate positions as indicated below.
- the device 1 further comprises a frame 63 on which are mounted one or more distribution nozzle (s) 2 and one or more rods (s) associated 3 and displacement means 6 of the shutter rod 3 which are illustrated in greater detail in FIGS. 8A, 8B and 9.

- the rods 3 fillings are fixed to the control cams by an upper retaining plate 62 visible in Figure 8B.
- the distribution nozzles 2 are furthermore fixed on the frame 63, for example by means of pylons 64 of the frame 63, illustrated in FIG. 8B in particular. Rotation of the shaft 65 thus makes it possible to move the shutter rods 3 relative to the distribution nozzles 2 in the vertical direction between the open, closed, contact and, where appropriate, release positions.
- the motor 60 and the shaft 65 of the displacement means 6 can be placed below the device while controlling the movement of the shutter rods 3 by their upper part, by means of the control cams 61 and the upper retaining plate 62. In this way also, it is possible to obtain a large amplitude of vertical movement of the closure rods 3 while limiting the size of the device 1.
- the shutter rod 3 may comprise an upper end 3c accommodated in a gripping element of the displacement means 6, for example by means of a groove.
- the shutter rod 3 may in particular be cylindrical except at its lower end 3a and its upper end 3c, in particular cylindrical of revolution.
- the shutter rod 3 is illustrated in FIGS. 1 and 2 in the open position. In the open position, the shutter rod 3 leaves free the distribution portion 4c of the central channel 4. In this way a flow of product is allowed from the inlet channel 5 to the dispensing opening 4a, via the opening intake 4b of the central channel 4.
- the shutter rod 3 is for example accommodated in the central channel 4. More precisely, as illustrated in FIG. 1, the central channel 4 has, for example, a guiding portion 4d located upstream of the portion of FIG. 4c distribution of the central channel 4, visible in particular in Figure 2.
- a guide portion located upstream of the dispensing portion it is particularly meant that the guide portion is located above the dispensing portion, or is further from the dispensing opening of the central channel than the distribution portion.
- the guide portion may in particular be a portion of the central channel not being intended to receive the product, even if its lower end may sometimes be in contact with the product rising from the dispensing portion, particularly when the sealing rod back into the nozzle above the intake opening.
- the lower end 3a of the shutter rod 3 is thus for example accommodated in the guiding portion 4d of the central channel 4 and leaves the delivery portion 4c free of obstacles. of the central canal 4.
- FIGs 3 and 4 illustrate the shutter rod 3 in the closed position.
- the shutter rod 3 closes the dispensing portion 4c of the central channel 4 so as to prevent product flow from the intake channel 5 to the dispensing opening 4a, via the intake opening 4b of the central channel 4.
- the lower end 3a of the shutter rod 3 can for example be accommodated in the dispensing portion 4c of the central channel 4.
- the lower end 3a of the sealing rod 3 can be arranged outside the dispensing nozzle 2, in particular arranged outside the dispensing nozzle 2 and in proximity with the lower end 2a of the dispensing nozzle 2.
- the lower end 3a of the shutter rod 3 may for example be arranged outside the dispensing nozzle 2 and at a distance from the lower end 2a of the dispensing nozzle 2, measured in the vertical direction Z, less than 2 centimeters, preferably less than 15 millimeters.
- the shutter rod 3 may comprise, upstream of the lower end 3a, a cylindrical closing portion 3b adapted to close the dispensing portion 4c of the central channel 4 of the dispensing nozzle 2 when the stem shutter is in the contact position and in the closed position.
- the shutter portion 3b may have a shape adapted to close the inlet opening 4b of the central channel 4 when the shutter rod is in the contact position and in the closed position.
- the closing portion 3b may for example have the shape of a cylinder of revolution.
- the intake opening 4b can then have the shape of a disc.
- a section of the closing portion 3b may be substantially identical to a section of the distribution portion 4c of the central channel 4, in particular substantially identical with a radial clearance sufficiently small to guarantee a correct seal between the distribution nozzle 2 and the sealing rod 3.
- a section of the closure portion may be substantially identical to a section of the dispensing portion
- the section of the closure portion may have dimensions sufficiently close to the dimensions of a section of the distribution portion to prevent the passage of the product when said sections are coaxial and brought into correspondence in the vertical direction Z.
- FIGS 5 and 6 illustrate the shutter rod 3 in the contact position.
- the shutter rod 3 extends out of the dispensing nozzle 2 through the dispensing opening 4a of the central channel 4.
- the shutter rod 3 extends through the dispensing opening 4a out of the dispensing nozzle 2 over a contact distance C greater than or equal to a maximum transverse dimension D of the shutter rod 3.
- the contact distance C is for example measured in the vertical direction Z between the dispensing aperture 4a and a lower end 3a of the shutter rod 3.
- the maximum transverse dimension D of the shutter rod 3 is measured in a plane perpendicular to the vertical direction Z.
- the maximum transverse dimension D of the shutter rod 3 can thus for example correspond to a larger diameter of the shutter rod 3.
