ABSTRACT:
A valve of a type for use particularly in animal waterers. A valve body having a passageway extending therethrough has a valve stem disposed in the passageway. The valve stem has an enlarged portion on one end thereof having longitudinal slots therein and a valve head on the other end thereof for cooperation with a valve seat located at one end of the passageway of the valve body. A screen having perforate sides and an imperforate end is connected to the valve body and encompasses the valve head. A cylindrically shaped member is positioned inside of the screen and is sealed at one end thereof to the valve body and at the other end to the imperforate end of the screen. A single small hole passes through the cylindrical member at a place on the cylinder whereby the valve head must move past it during opening and closing thereof to thereby keep the opening from being closed due to the build-up of foreign particles or mineral deposits thereon.
