ABSTRACT:
A controlled valve with the possibility of autonomous opening and an aircraft having a valve of this type are disclosed. The controlled valve enables the regulation of presures or flow rates. Furthermore, the disclosed control valve can open autonomously under the effect of a pressure difference exceeding a pre-determined threshold. Thus, it enables fast balancing of pressures if the pressure difference should exceed a threshold beyond which, for example, an installation could be in danger. The disclosed device can be applied to any device for the regulation of pressure and/or flow rate between a chamber and the exterior or between two chambers having a safety balancing device. The disclosure can be applied notably in aeronautical construction, the construction of petroleum refineries, fluid distribution devices and chemical reactors.
