ABSTRACT:
A drip irrigation emitter which is constructed of a tubular housing within which is located an internal chamber. A pressurized source of water is to be supplied to the internal chamber which is divided into a plurality of valve chambers. Within each valve chamber is mounted a ball. The ball is to be movable due by the water pressure to engage a valve seat. Formed within the valve seat are a plurality of minute flow passages through which the water is to seep or trickle into a closed chamber with therebeing a separate closed chamber for each valve seat. The closed chambers are formed within a cover, a separate distribution conduit is connected to each closed chamber through which the water is conducted to be deposited at an exterior location. Each of the distribution conduits is passed through a separate opening formed within the cover. The cover is fixedly mounted onto the housing. The cover prevents any sharp bend or "kink" occurring in the distribution conduit and minimize the entry of foreign material in contact with the upper end of the housing.
