Abstract: A controlled valve with automatic opening and an aircraft having a valve of this type. The controlled valve enables the regulation of pressures or flow rates. Furthermore, the 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 may be put in danger. The controlled valve 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, of fluid distribution devices and of chemical reactors.

Abstract: A controlled valve with clack valve and a clack valve including a controlled valve, as well as an aircraft with a controlled valve of this type, are disclosed. The disclosed controlled valve has a clack valve on its surface. The controlled valve is used for the "fine" regulation of pressure or flow rate. The clack valve enables safety balancing of pressure. The incorporation of the clack valve in the controlled valve or of the controlled valve in the clack valve makes it possible to have only one opening in the partition surface and, thus, to reduce the weight and cost while increasing security. 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, of fluid distribution devices and of chemical reactors.

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.
