A pressure snubber has a primary branch pipe with mouthpiece, secondary branch pipe with perforated tube, primary and secondary chambers and end gap. Working liquid from the mouthpiece goes out in several flows that are mixed in the primary chamber, and than one part of working liquid comes through the end gap to secondary branch pipe and the other one – through perforated partition to secondary chamber, then through radial openings to secondary branch pipe, and the other part – through perforated partition to secondary chamber, then through radial openings to secondary branch pipe in which flow mixing takes place, due to that pressure drop and suppression of flow energy take place. For control of process of suppression of the pressure value of resistance of the end gap is variable. The technical result is in increase of efficiency of suppression of pressure pulses of working liquid in pressure main and simplification of adjustment of suppressor to needed mode of operation. |
