A Fluid Control Valve by Making Use of Viscosity Increase of Dielectric Fluids Caused by Electrodes Planted with Hair-Like Short Fibers. Proposition of a Fiber Planted ER Valve.

Abstract

Recently Otsubo and Edamura reported that dielectric fluids showed striking viscosity increase on the application of electric fields when the electrode surface was planted with hairlike short fibers. By using the phenomenon. ER effect applications are expected without ER fluids. This study aims to develop a fluid control valve with the new ER effect. In this paper, firstly, the fiber planted ER valve, which have fiber planted high voltage electrode and normal surface ground electrode, is proposed. The valve can control fluid power with applied voltage. Secondly, a 2-port fiber planted ER valve is fabricated and the static characteristics and the dynamic characteristics are examined. Finally, as an application of a fiber planted ER valve, a 4-port fiber planted ER valve is proposed and fabricated. And then, it is demonstrated that a 4-port fiber planted ER valve can control a piston-cylinder.
