FIELD: machine building.
SUBSTANCE: device consists of straight-line pipe section of constant diametre, which is equipped in addition with in-series located extended pipe section ("coil") with diametre which is larger at least by 2 times than diametre of preceding straight-line pipe section, as well as with bypass tap connecting the above "coil" to the preceding straight-line pipe section; at that, axis of bypass tap and axis of "coil" are provided at acute angle, and axis of inset of bypass tap with axis of straight-line pipe section is provided at straight angle, and distance of the tap from "coil" to inset of straight-line pipe section is equal to the half wave of possible hydraulic impact.
EFFECT: improving reliability and decreasing considerable costs for operation of hydraulic impact damping device.
