Abstract
An improved low volume spray device for an irrigation system comprises upper and lower separately molded plastic members that may be assembled before or after the lower member is installed on a fluid conduit. The lower member, which is secured within the conduit, is molded with a conical deflector portion that receives the main force of the liquid stream from the conduit. An upper head member snaps onto the lower member and has a peripheral series of spaced apart teeth adapted to receive liquid from the conical deflector and separate it to form a uniform spray pattern of radially directed streams. Since the main fluid force is on the conical deflector, fluid pressure cannot act to separate the upper member when in use.
