Annotation The current state of the development and study of vortex jet devices that are used as control valves based on the working medium vortex flow principle is reviewed and analyzed in the article. The scientific and technical literature is reviewed. The article considers vortex valves without mechanically moving parts, as well as a semi-mechanical vortex valve. The principle of operation of a vortex jet device is described. The rationale of the use of a vortex jet device as an actuator in a valve for controlling the flow of a working medium, as well as in a control system of a sleeve-valve cylinder, is given. The classification of vortex jet devices by the feed type of the supply and control flows of the working medium is carried out for the first time.
