A device in a drinking fountain, or waterer, for cattle comprises a valve head (1), and openable shut-off valve and a diffuser (2). The valve head (1) is connected to a water conduit and has an outlet aperture (15) which discharges interiorly in the diffuser (2). The diffuser (2) is connected to the shut-off valve for its operation and has an inlet (21) for the suction intake of air in the water. Further, the diffuser (2) extends into a circumferential groove (20) in the valve head (1) with a certain clearance. A circumferential wall (19) surrounds the groove (20) and is substantially formed as a casing surface of a cylinder. |
