Abstract
Watering valves (10) allow animals to cover their water requirements on their own accord. Accordingly, the animals actuate an actuating section (33) of a valve pin (13), which projects from a housing (12) of the watering valve (10), by either tilting or pushing up on the valve pin (13). Smaller and weaker animals, in particular chicks, are often incapable of tilting the valve pin (13) far enough to open the watering valve (10). On the other hand, the watering valve (10) must close reliably when the respective animal no longer actuates it. Conventional watering valves (10) achieve this only through such means which make it more difficult to actuate the watering valve (10). The watering valve according (10) to the invention has two valve seats (34, 35) in the interior of the housing (12). One valve seat each (34, 35) is assigned to the valve pin (13) as well as to an upper pin (14) arranged above the valve pin (13). In this manner, and in particular with the use of a raised head (31) of the valve pin (13), the requirements outlined above can be met by ensuring an easy actuation of the watering valve (10) and a reliable closing of the same.
