A fluid flow control device particularly useful as a drip-irrigation emitter is described comprising a two-section housing in which a mounting section is adapted to be passed through the wall of a supply pipe with the housing main section disposed within the tube and the outer end of the mounting section open to the atmosphere. A disc is freely movable within the housing main section and includes a stem fixed to one face thereof and passing into the housing mounting section such as to provide a fluid passageway therebetween. The housing main section is formed with an opening facing the face of the disc to which the stem is fixed, the arrangement being such that when pressurized fluid enters the housing main section through the opening, the disc moves towards and away from the opening to control the flow of the fluid into the housing and thereby through the fluid passageway between the disc stem and the inner face of the housing mounting section.
A fluid flow control device particularly useful as a drip-irrigation emitter, comprising a housing including a control member disposed within but unattached to the housing so as to be freely movable therein, said housing including a wall formed with an inlet opening and an outlet opening both facing the same side of said control member and located so as to be covered and uncovered by said side of the control member as the control member moves towards and away from said wall of the housing.
