US 5,329,877 A · Watering valve for small animals having variable flow rates

Abstract

The watering valve (10) according to the invention is designed for feeding of water to the chickens according to their need for water in such a way that a flow restriction section (27) which is formed between an upper pin (16) and a part of the housing (12) associated therewith is variable in order to set different water flow rates. For this purpose, the upper pin (16) is provided with portions (25, 26) of different diameters. A variation of the relative position of this upper pin (16) in the housing (12) makes it possible to enlarge or reduce this flow restriction section (27). Accordingly, a smaller or greater quantity of water (per unit of time) can flow out of the watering valve.
