A Novel Three-Position Three-Way Integrate High Speed On/Off Valve Pair With Opposite Reverse-Drive Three-Level Strategy

Digital hydraulic systems (DHSs) are increasingly adopted in aerospace applications due to their high reliability and robustness. However, the dynamic performance of the high-speed on/off valve (HSV) directly affects system response and control accuracy, while aerospace applications simultaneously impose stringent demands on miniaturization. Existing HSV struggle to resolve the tradeoff between high performance and a compact form factor. To address this challenge, this study proposes a novel integrated HSV pair (IHSVP) combined with an opposite reverse-drive three-level strategy (ORTS). Structurally, the IHSVP utilizes a single mover to cooperatively control two ports, achieving a three-position three-way…
