ABSTRACT:
A flow reducer device particularly useful as a drip irrigation emitter, includes a body member having a flow regulating region formed with a cavity extending through the body member and closed at its opposite sides by a deformable diaphragm, preferably an elastomeric sleeve. The device is attachable to a tube 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, such that the diaphragm sides deform towards or away from each other within the cavity to regulate the fluid flow.
