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.

Abstract: A device for regulating the pressure and/or flow of pressurized gas, comprising a body with a gas inlet, a gas outlet and a gas passage connecting the outlet with the inlet, a pressure reducer and a flow selector arranged downstream of the pressure reducer, a hand-wheel rotatably mounted on the body and cooperating with the flow selector for adjusting the flow, and a pressure indicator located at the center of the hand-wheel. The device comprises also a shaft rigidly fixed to the body and rotatably bearing the hand-wheel, the shaft supporting the pressure reducer and comprising a gas channel fluidly connected to the gas passage in the body.

Inventor： Privat Roderes ,  Jean-Claude Schmitz

IPC: G01F23/26

Abstract: The invention is directed to a gauge body for a container for pressurized gas, comprising a mounting surface for mounting the body to the container; an inner side in contact with the pressurized gas when mounted on the container; an outer side opposite to the inner side with regard to the mounting surface, the outer side being outside of the container when the body is mounted on the container; an electrical lead extending in a gas tight manner through the body from the inner side to the outer side. The electrical lead comprises a metallic rod and a bushing around the rod, the bushing being mounted a gas tight manner on the body.

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: The invention is directed to a valve for gas under pressure, for example at temperatures below −100° C., comprising a body with a gas inlet, a gas outlet and a passage connecting the inlet with the outlet; a shut-off device for closing the gas passage; a spindle designed for operating the shut-off device; and at least one gasket between the spindle and the body. The valve further comprises at least one cavity around the spindle for accumulating particles separated from the at least one gasket while operating the spindle and the shut-off device, for example at temperatures below −100° C.
