A flow reducer device (14) particularly useful as a drip irrigation emitter includes a body member (16) having a flow regulating region (26) formed with a cavity (44) extending through the body member (16) and closed at its opposite sides by a deformable diaphragm, preferably an elastomeric sleeve (18). The device (14) is attachable to a tube (10) of pressurized fluid such that the outer face of each diaphragm side is exposed to the fluid pressure at the fluid inlet, and the inner face of each diaphragm side is exposed to the fluid pressure within the cavity (44), such that the diaphragm sides deform towards or away from each other within the cavity (44) to regulate the fluid flow. <IMAGE> |
