AUTOMATICALLY FLUSHING WATER REGULATOR FOR ANIMAL WATERING SYSTEMS

摘要

A water pressure regulator (9) is provided with a water inlet member (51) comprising a watering path (73, 121) and a flush path (75, 123). The watering path (5) is operably engaged by a regulating valve. The inlet member (51) is manually movable relative to the housing (21), to position the watering path outlet relative to the regulating valve to prevent the regulating valve from engaging the inlet member, thereby placing the regulator a flush mode. The flush path (75, 123) has a water exit into the regulator 10 spaced from the watering path po and hence is not engagable by the regulating valve. A flush valve (85) is provided in the flush path, and is moveable between a closed position in which the regulator will operate in a drinking mode and an open positio in which the regulator will be in a flush mode.
