FIELD: process engineering.
SUBSTANCE: invention relates to generators of fluid jet pulses and can be used at hydraulic cleaning of various materials. Hydraulic pulse generator comprises case with fluid feed pipes, cover with discharge nozzles, drive shaft disc-like clipper with circular cut-outs. Nozzle inner surface is provided with lengthwise ribbing with cross-section shaped to equal sectors of circle with central angle of 60 degrees with truncated vertices.
EFFECT: more efficient effects of pulse jet owing to separate pulses swirled around lengthwise axis.
