ABSTRACT:
A drinker for chicken has a base, an outer case, a spring casing, a pull rod which is a match for the clearance of the spring casing, and a lever. The pull rod is connected to the combined part of a guideway ringlike valve at an end, and with the spring casing, forms two ringlike clearances within the case. A guide, a washer for the valve and an opening in the base form a clearance, which allows a jet-like spray of water to enter the case. The difference in the sectional areas between the clearances slows the velicity of the water. The time and the volume of water supply can be controlled be adjusting the stroke of the pull rod. By means of a back and forth movement of the guide and the pull rod, creating a jet-like spray, scale (mineral deposits) or any other contamination can be removed from the valve nozzle and the interior of the case. The result is a drinker which has no leakage nor any blockage because of scale build-up, and which is simple in structure and low in cost.
