Abstract: A fluid injection flow control device for use in oil wells, designed to maintain, the injection rate within a determined layer between two packers, being the puncture zone of an injection well. The device, is axially coupled to a tubing string, consists of a variety of modules formed by an upper coil carrier onto which a primary coil is helically wound which, is connected to the pipe through which the fluid flows, causes a certain load drop in a side-pocket mandrel, which consists of two main parts namely a tubing string that allows for axial tubing continuity and a pocket in which a short or long flow direction vane is installed that determines the outflow towards the unit by way of a transverse opening or its passage to the next module's corresponding coil through transition tubing.
