<p>This application is directed to an apparatus for exact dosing of a fluent additive, especially a medicine, into the drinking-water intended for cattle. The drinking-water is pumped up from a well or a reservoir by means of a pumping device driven by the cattle, when the drinking water is required, and comprises a piping for the additive, which is connected, by means of a tight gasket, to a main suction piping. The piping for the additive is connected at its other end to a dosing member with a built-in nonreturn valve placed in a container with the additive. The dosing member is provided with a cross-sectional opening for passage of the additive, which cross-sectional opening is determined by a replaceable nozzle.</p> |
