发明名称 Two-piece low volume spray device
摘要 A low volume spray device for an irrigation system comprises upper and lower separately molded plastic members that are assembled before being installed on a fluid conduit. The two piece construction allows the upper or head member to be molded with a deflector portion having an exterior shape capable of forming a uniform spray pattern. The upper head member also has a lower tubular portion adapted to extend into the fluid conduit as well as around the lower member so that fluid pressure cannot act to separate the two members when in use.
