Description

In this paper, a flow rate servo system composed of an isothermal pressure vessel and a solenoid valve controlled an on-off method is proposed. In this method, the pressure fluctuation caused by switching action of valve cannot be avoided. However, this pressure fluctuation enables to examine the output flow rate by calculation. Therefore, it can be realized the dynamic flow rate servo system by yielding a desired flow rate directly.<br>The accuracy and responsibility of the dynamic flow rate servo system employing the solenoid valve and the isothermal pressure vessel are shown. And for the evaluation of this system, floating position control of the sphere ball is a “spout” toy for child and the control needs very delicate control of flow rate is tried. The method for suppressing the pressure fluctuation, which arises by the switching of solenoid valve, is proposed.
