New Valve Design for Switch-Mode Hydraulic CircuitsA high-speed three-way crank-slider valve can be used in switch-mode hydraulic circuits. Its unique drive mechanism features two valve spools axially driven by crank-slider mechanisms. By phase shifting the two crank links, which are on a common cra.....
