When adopted, the Central angle of the circular cutout in the web clipper duration full opening and full closing of the nozzle holes respectively equal to 0.33 and 0.67 sec. This gives the opportunity with some approximation to reproduce the duration of the character pulse jets, obtained using electrohydraulic effect (see the article in the book Vodovatova S.D., Kochetkov, P.P., polanin YA, Titova, A.D. Study the transport capacity of the flow generated by a pulsed jet. // Sat. papers No. 58. V.2. The scientific work of the departments of forest engineering and mechanical departments. - Yoshkar-Ola: PLTI, 1968. - Pp.92-93). Disadvantages are the occurrence of water hammer inside the housing with tube feeding liquid, which affects the reliability of the entire hydraulic system hydrogenerator, as well as insufficient liquid spray due to one-time (single) output pulse jet idcation the exhaust nozzle. Known also hydrogenerator containing the cover with evenly spaced outlet holes nasdaw and disk cutter with circular cutouts arranged offset relative to nasdaw (see author's certificate No. 1389863 from 25.06.86, class MKI VW 1/08). The disadvantage is the lack of the impact energy of each pulse of hydraulic jets when they meet with an obstacle. Technical result - increase the efficiency of the pulsed jet due to the formation of separate twisted around the longitudinal axis of the pulse. The technical result is achieved by the fact that hydrogenerator contains the disk cutter with a circular cut is made in the form of a truncated near the top sector of a circle with a Central angle of 60° and cover with a console mounted rotating nozzles on the inner surface of which is made a longitudinal fins with a cross-section in the form of equal sectors of a circle with truncated vertices.
