A cylindrical part threaded at both ends is provided with two oblique internal channels having different diameters. The channels are in an axial plane and open to the outside at one end and at the median, non-threaded zone. The part is inserted between upstream and downstream portions of the supply pipe of the drinking bowl at a union It is screwed in a threaded hole of the union from the bottom of which issues the downstream portion so that the communication between the two portions is established through one of the channels. |
