device for adjustment of fflodesmengden at a drickho

摘要

The device adapts the rate of flow of an automatic drinking bowl as a function of the pressure prevailing in the installation to which it is connected, and is constituted by a cylindrical part threaded at its two ends and provided with two oblique internal channels having different diameters, each being located in a radial plane of the part and opening to the outside of said latter on the other hand at one of its ends and on the other hand in its median, non-threaded zone; the part is inserted between an upstream portion and a downstream portion of the supply pipe of the drinking bowl at a union, by being screwed in a threaded hole made in the male element of the union and from the bottom of which issues the downstream portion so that the communication between the two portions is established through one of said channels. The invention finds advantageous application in equipment used in stock raising.
