Abstract
A multi-actuation system includes a first electrohydraulic servo valve and a first actuator. A first fluid line fluidically connects the first electrohydraulic servo valve to the first actuator. The multi-actuation system also includes a second electrohydraulic servo valve and a second actuator. A second fluid line fluidically connects the second electrohydraulic servo valve to the second actuator. A ring fluidically connects the first fluid line with the second fluid line.
