Abstract
In the first report, a sound operated directional control valve was proposed in order to widen the application of pneumatic drives to a multi-degree-of-freedom wearable system. In this paper a main valve is proposed which can be driven by a small pilot pressure change to compose a sound operated directional control valve. First, the working principle of the main valve and the method to decide the parameters of it are explained. Next, the characteristics of the sound operated directional control valve which consists of a pilot valve and a main valve are investigated experimentally. Furthermore, preliminary experiments are conducted which use two sound operated directional control valves to control multi-actuator. Finally, a multi-degree-of-freedom wearable pneumatic system is constructed by using a Dry-Ice Power Cell as the portable gas supply, wearable actuators developed in a previous study, and two sound operated directional control valves developed in this paper. Experimental results show that the sound operated directional control valve is feasible and practical.
