Abstract: An irrigating device and a deflector for even spraying of liquid across non-circular areas are presented. The irrigating device includes a base comprising at least a groove; a cap; and a deflector including at least a butterfly ridge, a groove, and a plurality of hydrodynamic ribs, wherein the butterfly ridge is structured with a continuous series of angles to allow equal quantity of liquid per distance on the radius and diagonal, wherein the groove is structured to allow full liquid coverage at a zero point, and wherein the plurality of hydrodynamic ribs are structured to control at least the irrigated distance.
