Dispensing device, in particular for filling machine feeder, and feeder equipped with same

Distribution device for selectively establishing one fluid passage channel from several fluid passage channels and intended in particular for a filling machine measurer including a body or faucet (1) in which a distribution key (3) with a vertical axis (X-X) is rotatably mounted, said body comprising a truncated seat (2) open at its base and top and having a side opening (22), for receiving the distribution key (3) whose truncated portion is open at its base and has a side opening (32) and is also open at its top in a axial extension tail (31) coming downwards out of the faucet (1) and open at its distal extremity, said side openings (22, 32) being fluid passage openings extending one another for a specific rotation position of said distribution key (3) around (X-X), characterised in that an outlet joining piece (4) with a sealing function is mounted on alignment at the end of the extension tail (31) whose operational movements are linked to those of the distribution tail (3), said outlet joining piece (4) with a sealing function being controlled on opening and closing via the rotation of an internal joining piece (40) in a fixed external joining piece (45), said internal joining piece (40) being connected to the extremity of the tail (31) of the distribution key (3) so that it is integral in rotation with the latter, the external joining piece (45) internally having a recess (49) between two upper and lower bores calibrated to the outer diameter of the internal joining piece (40), and means being provided to move in translation along (X-X) the unit formed by the distribution key (3) and the internal joining piece (40) between their functional position and a cleaning position in which the distribution key (3) is slightly spaced from the seat (2),whereas the extremity of the internal joining piece (40) is lifted into the recess (49) of the external joining piece (45).
