Title: System for limiting rate of pressure rise in pipeline during hydraulic impact

Abstract: The system for limiting the rate of pressure rise in a pipeline during a hydraulic impact comprises a jet valve installed in the pipeline, an additional outlet of said valve being connected with a non-pressure dump tank via an actuator, and a pressuretight pneumatic compensator connected with the jet valve and, via a pressure transmitter, with a rate of pressure rise signal indicator whose outlet is connected with the membrane drive of the actuator.
