Abstract: The invention is directed to a method for improving the mechanical behavior of a metallic body (4) comprising an internal volume for a fluid and at least one threaded connecting port (6, 8) to said internal volume, the method comprising a step of treatment by autofrettage of the internal volume by applying a pressure to a liquid inside said volume. The autofrettage step comprises closing the internal volume by screwing a plug (28) to each the at least one threaded connecting port (8), so that the thread(s) of said port(s) is/are also subject to the autofrettage treatment. The invention is also directed to a body (4) resulting from such a treatment, with compressive stresses at the root of one of the most carrying turns of the thread of each of the connecting ports. The compressive stresses improve the fatigue behavior of the body.

Abstract: The invention is directed to a valve actuating device comprising a body with a bore and a bottom, an actuating element sealingly housed in the bore of the body and forming a first chamber with the body, a piston sealingly extending through a bore in the actuating element, the piston and bore delimiting a second actuating chamber, a passage for an auxiliary fluid between the first and second chambers so that a movement of the piston in the bore of the actuating member can increase the pressure in the first chamber and move the actuating element. The fluid passage comprises a restriction and a check-valve, both arranged in parallel, so as to limit the flow of the auxiliary fluid from the second chamber to the first chamber.

Abstract: The invention relates to a device for regulating the flow rate and/or pressure of a fluid, such as valve for a pressure gas cylinder, comprising a reducing valve including a first plug designed to be moved in the normal flow direction of the fluid during closure. The reducing valve also comprises a plunger to which the plug is coupled. The face of the plunger that is oriented towards the first plug defines a regulation chamber together with the body. The aforementioned face also comprises a seal that engages with a corresponding surface of the body such as to form a second plug for maintaining residual pressure. The regulation device also comprises a means for preloading and releasing a spring acting on the opposite face of the plunger.

Abstract: A method for calculating the remaining usage time of a gas cylinder equipped with a pressure reducer, the method comprising the following steps: (a) measuring the pressure of the gas in the cylin-der; (b) calculating the variation of pressure of the gas in the cylinder over time while gas is out-putted; (c) calculating a remaining usage time Tr based on the measured pressure in the cylinder and the calculated variation of pressure. Step (c) takes into account characteristics of the pressure reducer relative to variations of its nominal flow rate along the decrease of its inlet pressure while emptying the cylinder.
