Abstract: The invention relates to a fluid film bearing, and more particularly the improvement of the load capacity and stability of such a bearing.The fluid film bearing comprises a housing 7 and several bearing sub-assemblies each comprising a flexible leaf 2, a leaf reinforcing element and a support bar (5), the sub-assemblies of the bearing being fixed to the housing by insertion of each bar 5 into a groove provided in the housing. The reinforcing element comprises an upper stiffener 3 secured to the bar of a sub-assembly, and a lower stiffener 4 secued to the bar of an adjacent sub-assembly, the two stiffeners 3 and 4 overlapping on at least one part of one of their faces. The bearing is advantageously provided with a preloading spring 6.The bearing is particularly useful in turbo engines, especially whey they form part of aircraft, more particularly military aircraft.

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: An air-conditioning installation for aircraft, especially for passenger aircraft is disclosed. The energy resulting from the expansion of the air that leaves the cabin is used to actuate at least one element of the installation such as an expansion turbine or a compressor. The temperature of the air leaving the expansion turbine is lower than the temperature of the external air.

Abstract: A conditioning method and an air-conditioner for carrying out such method which comprises, in a compression, cooling and expansion cycle, a drying operation performed prior to the expansion. According to the invention, a dryer is alternately operated in an adsorption phase and a regeneration phase, depending on whether it communicates with the outlet or the inlet of a heat exchanger. The present method and device can be advantageously applied to environment control in the field of aircraft and automotive vehicle air conditioning.

Abstract: A method and apparatus for conditioning air in an enclosure wherein the air is passed through a heat exchanger where the air is heated or cooled by a primary gas in the heat exchanger; the primary gas flows through a conditioning power circuit wherein the primary gas is compressed thereby heating the same; the compressed primary gas is then either passed through the heat exchanger to heat the air or is further compressed, cooled and allowed to expand to cool the primary gas which then passes through the heat exchanger to cool the air.
