A liquid-jet nozzle device contains a cylindrical tube with conically tapered output part and a straightener in the form of installed with a clearance along axis of the tube groups of longitudinal walls placed in it. The straightener is made in the form of two groups of longitudinal walls, the first of which is installed with formation of at least four channels, and the second - at least nine channels. The length of the first group of partitions is equal from 1.0 to 1.2, the length of the second group of partitions - from 1.3 to 1.6, and clearance between the groups is selected as being equal to 0.2 of inside diameters of the tube.
