Abstract

A pressure regulator for supplying water to an associated watering system for poultry or the like includes a top works structure and a bottom works structure which are formed of few parts, which are easy to manufacture and assemble together. The top works structure includes a cover seated within a cover and a reference spring assembly which includes a reference spring and a diaphragm membrane. The reference spring assembly can be adjusted to vary the outlet pressure of the regulator. The bottom works structure includes a body having an inlet through which water flows into the regulator from a supply and an outlet through which water flows out from the regulator to the associated watering system. A structure is provided for substantially isolating said diaphragm from water pressure in said regulator during flushing of the regulator and the associated watering system and during conditions of higher-demand for water. An ejector tube arrangement is provided in the housing outlet for boosting the flow of water through the regulator under a higher demand condition.
