Abstract
A fluid flow control device particularly useful as a multiple-emitter for drip irrigation comprises a housing defining an internal chamber and a freely-movable control member disposed within the chamber and unattached to the housing. The housing includes a waLl defining one side of the chamber and formed with an inlet opening and a plurality of outlet openings. All of these openings face the same side of the freely-movable control member and are located so as to be covered and uncovered by the same side of the control member as the control member moves towards and away from the wall of the housing. The device further includes an inlet tube for connecting the inlet opening to a source of pressurized fluid, and a plurality of outlet tubes, one connected to each of the outlet openings, for conducting the fluid exiting from the respective opening to the point of use of the fluid.
