| Outline of Final Research Achievements |
In this study, we are developing a compact flow control valve capable of continuously adjusting micro flow rates for pneumatic actuator control.The control valve we are developing is a control valve in which particles are sealed inside an air duct as a valve plug, and a piezoelectric element controls the microscopic motion of the particles on the orifice, enabling control of fine flow rates with high response.During the research period, a system that enables observation of the inside of the control valve was created to clarify the effects of particle motion and fluid behavior on the vibration of the orifice plate, and to confirm the optimum vibration conditions of the orifice plate for driving.

空気圧機器の特徴として小型軽量であるが，制御性が低いという問題点がある．この問題の解決のために新たな制御弁の開発が行われている．申請者は以前より，制御性の高い機器として微粒子励振型流量制御弁を開発している．本研究では，開発している制御弁の応答性の改善と制御流量の微細化が可能な駆動原理を提案し，その有効性を評価した．この結果より，今までの駆動原理では実現できなかった微小流量の連続制御が可能となり，空気圧機器の応用分野の拡大の可能性を示した．
