摘要

To tap nozzle revolving curve and plastic injection process of bica curve. The invention relates to a spinning nozzle curve, tap, which is injected in single piece and composed of two segments together curved, each with a specific radius and constant, and the process of the injection nozzle curve.The nozzle (1) is formed by two curved portions (14 and 15) of constant curvature that are interconnected and integrated, forming a single piece. This design permits rectilinear edges from the state of the art.The curve of the lower portion (14) of the nozzle is formed by a radius longer (R), which defines a substantially vertical passage, while the curve of the upper portion (15) of the nozzle is formed by a radius shorter (R), necessary to enable the direction of the water jet down. The meeting of the two curved portions (14 and 15) results in an inflection point (16) in the curvature of the nozzle (1).Internally, the meeting of the two curved portions of the channel (17) form a lateral deviation (18) which compensates for the differences in the radii (R and R). The ends of the nozzle (1) with the channel (17) constantly curved, while the external surfaces (11 and 13), rectilinear, for fitting in the duct out of the faucet and the thread (13) of the conductorof the water jet, respectively.The injection process employs a mold and two males (5 and 6) which move in opposite directions for obtaining the internal channel of the nozzle. The males (5 and 6) are curved and have a radius of curvature is constant, which allows it to retreat without damaging the molded nozzle (1).The meeting of the males (5 and 6), due to the differences of the length of radii (R and R) and the shape of the nozzle (1) occurs with defasamento resulting in a discontinuity (18) of the internal channel of the nozzle (1).
