Rephase Cylinders are used in synchronized linear-actuator applications. Two or more cylinders are plumbed in series, with bore and rod diameters sized. Synchronization eliminates need for a separate flow divider or mechanical torque tube, external circuitry, devices, or plumbing. They provide parasitic power losses, pressure intensification and the ability to transfer power between actuators.
