Continuous air control using particle excitation valve

In this paper, we report a new prototype of the particle excitation flow control valve to control flow rate continuously. The purpose of this study is the development of the valve that can precisely control pneumatic cylinders. We reported this flow control valve principle in the previous paper and concluded the diameter of orifice is an important parameter for flow rate change. In this report, we have designed a new prototype for the purpose of high controllability. We have measured flow rate characteristics and confirmed the conditions necessary for continuous adjustment of flow quantity by experiment.
