Equipment used in mining for hydraulically conveying rock or alternatively for cleaning boilers uses a high pressure pulsating hydraulic flow. To increase the effectiveness the pulsation frequency can be increased. - The control arm of the resonator is formed as a short tube connecting the high pressure and discharge chambers. Its length is twice the length of the impact tube. (First major country equivalent to CS8604986) (Dwg.No.1)
