The invention relates to a device for mixing an aqueous solution of concentrated, in particular of the water and liquid polymers. & br / this apparatus has a channel 45 of water, of annular cross section, formed between an outer wall 49 of a body 1 and a central core 13, 33 and having a conicity directed towards the downstream. A central channel 27 of the concentrated and the channels 43 of the supply of concentrated pass through the core 13, 33, whose diameter decreases sharply, downstream of the openings 47 of the channels 43. The core 13,33 is adjustable longitudinally in the body 1 and the channel 27 has a valve 37 - 41 of the return flow. & br / field of application: assisted recovery of petroleum. & br / (see appended drawing in bopi) & br / & & br /
