The method of generation of pulsations of liquid jet consisting in that acoustic pulsations generated by acoustic actuator act directly or indirectly on the pressure liquid in acoustic chamber; generated pressure pulsations are amplified by mechanical amplifier of pulsations and transferred by liquid waveguide fitted with pressure liquid feed to the nozzle and/or nozzle system. An apparatus is used for implementation of this method comprising the acoustic system, consisting of acoustic actuator, an acoustic chamber which internal volume being filled with stationary pressure liquid, a mechanical amplifier of pulsations, and liquid waveguide; said acoustic chamber is fitted with mechanical amplifier of pulsations that is connected with the nozzle and/or nozzle system by means of liquid waveguide that is fitted with pressure liquid feed.
