Low frequency, high intensity sound is produced using a conduit having a flow of high velocity and low pressure air. A pair of sound ports are provided in the conduit, and a rotary valve connected to a reversible servomotor and audio source is employed to direct the flow of air toward and away from the ports.

Magnetorheological valve in servo applications
Journal of Intelligent Material Systems and Structures, 2011In this article, the servo property of a high-performance magnetorheological valve will be evaluated by closing the pressure feedback loop. The magnetorheological valve developed in this study has two separately controllable fluid flow channels and is especially designed for high-frequency applications.

Development of rotary servo valve
Proceedings of the JFPS International Symposium on Fluid Power, 1993Conventional electro-hydraulic servo valves have sleeves and spools which move axially to control the flow of fluid. However, very high manufacturing technology is required to make them. This paper describes a newly developed rotary servo valve that has a simple structure and is directly operated.

Low noise hydraulic servo valve
The Journal of the Acoustical Society of America, 1979A fluid flow control valve which includes a body formed to define a chamber having inlet, outlet and actuating ports for supplying and receiving fluid to and from external hydraulic machinery to be actuated and including a valve spool formed with several lands and slidably arranged in the chamber for controlling the flow of fluid through the ports, in ...

Research of non-servo valve electro-hydraulic servo system
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011A new non-servo valve electro-hydraulic servo system was researched. To control load, the system uses bidirectional fixed displacement hydraulic pump that is driven by AC PMSM directly drives servo-hydraulic cylinder. The hydraulic actuating unit was designed base on one design parameter and performance target.
