| 摘要 |
The present invention discloses a flow reducing device, particularly useful as a drop-wise irrigation emitter including a body member having a region for the regulation of flow, which comprises a cavity extending through the body member and being closed at the opposite sides thereof by a deformable diaphragm, preferably an elastomeric bushing. The device of this invention can be attached to a pressurized fluid tube in such a way so that the exterior surface of each of the diaphragm lateral sides is exposed to fluid pressure on the fluid input, and the interior surface of each of the diaphragm lateral sides is exposed to fluid pressure inside the cavity, so that the diaphragm lateral sides are deformed in the direction of, or spaced apart from each other inside, the cavity in order to regulate the fluid flow.
