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.

A flow reducer device attachable to a tube of pressurized fluid for reducing flow of a fluid therefrom, comprising: a body member formed with a fluid inlet, a fluid outlet, and a flow regulating region between said inlet and outlet; said flow regulating region including a cavity extending through opposite faces of the body member closed by a side of a deformable diaphragm at each of said opposite faces; said body member being further formed with an inlet passageway leading from said fluid inlet into the cavity, and an outlet passageway leading from said cavity to the fluid outlet; said body member being formed with a plurality of baffles to define a labyrinth in said inlet passageway for reducing the pressure of the fluid flowing therethrough into said cavity; said device being attachable to the tube of pressurized fluid such that an outer face of each diaphragm side is exposed to fluid pressure at said fluid inlet, and an inner face of each diaphragm side is exposed to fluid pressure within said cavity, whereby the diaphragm sides deform towards or away from each other within said cavity in response to changes in the inlet pressure to regulate the fluid flow via said cavity to said outlet passageway.
