<p>The animal automatic drinking vessel has a wall bracket and a jet at the edge nearest the latter between two parallel faces. The jet forms a valve seat working with a sealing cap moved by a control blade on a horizontal axis and spring-loaded. A recess is formed between the wall bracket and the two side as far as the rear of the blade, forming a water flow channel from valve to blade free end. The width of the recess is such that with the valve fully open the blade is accommodated inside it, its end protruding with the valve shut.</p> |
