Classification of Vortex Jet Devices for Gas Flow Control in Pneumo-Hydraulic Systems

Abstract

This article presents a review and analysis of the literature on the development and study of vortex jet devices that are used as control valves employing the principle of the vortex flow of the working medium. The article discusses vortex valves without mechanically moving parts, as well as semi-mechanical vortex valves. The principle of operation of a vortex jet device is described and, for the first time, a classification of vortex jet devices by a number of structural and functional features is carried out. The analysis of technical solutions identifies the advantages and disadvantages of vortex jet devices. Recommendations are given for selecting a structure diagram of a vortex jet device.
