Abstract:
A liquid dispensing device (100), in particular for watering animals, in particular laboratory animals, such as small rodents or the like, said device (100) comprising a main body (101) which defines a longitudinal cavity (1011) for the passage of watering liquids, said longitudinal cavity (1011) being in communication with the outside through a delivery (1002) and a discharge (1001) for introducing said liquids in said longitudinal cavity (1011) and discharging said liquids from said longitudinal cavity (1011) respectively, a valve body (105) and an annular shape elastic sealing element (120) arranged inside said longitudinal cavity (1011), said valve body (105) comprising a stem with a first portion (106) which extends through said annular sealing element (120) and a flange-shaped head (107), wherein said flange-shaped head (107) is kept pressed against said annular sealing element (120) by means of an elastic thrust element (130), and wherein said stem can switch between a first closing position, in which the flow of said liquid downstream of said annular sealing element (120) is prevented by said annular sealing element (120), and a second opening position, in which the flow of said liquids downstream of said annular sealing element (120) is possible.
