Abstract
A flexible response secured mechanical balancing device (D) for multiple hydraulic control actuators (-) with a common output member (-). The balancing device (D) provides flexible/continuous fluid-pressure force fight compensation. Balance valves (-) are commanded to balance fluid-pressure from a first fluid-pressure network () of a second actuator (). Each fluid-pressure commanded balance valve (-) is arranged to allow relief of differential pressure, directly into a dedicated first () or second fluid-pressure network (). A fluid-pressure controlled locking device (-) is allowing inhibiting the corresponding pairs of balance valves (-) e.g. in case of loss of fluid-pressure. The invention typically applies to vehicles (A) including: aircrafts, rotorcrafts, drones.
