摘要:
A hydrodynamic nozzle for the cleaning of pipes and channels exhibits a distribution chamber (7), joining to the pressurized water-entrance opening (4), wherein the pressurized water-discharge opening (5a, 5b) join into the distribution chamber (7) through channels (6a and 6b). The distribution chamber (7) exhibits a cone-shaped water subdivider (8), to which a defined radius (r1) follows, wherein the curvature of the radius (r1) is opposite to that of the pressurized water-entrance opening (4). The channels (6a and 6b) are merging tangentially at this radius (r1). Furthermore, the nozzle body (1) can be subdivided into an upper part (2) and a lower part (3), and can exhibit a separate form element (14), which forms the water subdivider (8) and the radius (r1), in the lower part (3). The degree of effectiveness is substantially increased with the nozzle according to the invention and thus the axial pressure of the exiting beam of liquid and the cleaning effect is substantially increased.
