| 摘要 |
The invention concerns a drip-feed valve comprising a seal (1) having a cylindrical nozzle wherein a valve pin (5) can rotate or slide, the seal (1) having locally around the sliding gate (5) a cavity (11), communicating with the nozzle and open in the water reservoir (2), the valve pin (5) having at its lower end a first zone (51) along an axis for adjusting the drip-feed flow by rotation. The invention is characterised in that the valve pin (5) comprises a groove (511) parallel to the axis of the valve pin (5) emerging downwards and the cavity (11) of the seal (1) has a depth and/or a width gradually flaring from a closed angular position of the valve up to a completely opened position. |
