Rephasing cylinders

Rephasing cylinders save costs for synchronized linear-actuator applications. Two or more cylinders are plumbed in series, with bore and rod diameters sized so all rods extend or retract equally when flow routes to the first, or last, cylinder in the series. Synchronization eliminates need for a separate flow divider or mechanical torque tube, external circuitry, devices, or plumbing. Advantages include lower parasitic power losses, pressure intensification, and the ability to transfer power between actuators. Energy Mfg. Co., (319) 465-3537, www.energymfg.com
