Abstract (en)
[origin: EP0284830A2] The device which is particularly suitable for concrete dry injections is provided with a dry concrete mixture inlet and a water supply arranged around the latter. A water nozzle ring (12) on which water passages (28) which extend preferably evenly over the annular circumference and essentially radially and are inclined with respect to the annular longitudinal axis are arranged, serves for constantly changing the overall nozzle cross-section (28) for the water directly before it joins the concrete mixture. In this device, the amount of water is controlled by changing the nozzle cross-section directly before the water outlet itself with an essentially constant nozzle jet speed. For this purpose, a hydraulic, manually actuated adjustment device which is very easy to handle and operates on a displacement basis is used. <IMAGE>
