摘要： The invention relates to a valve device including a built-in expansion valve and a flow selector. The valve function is provided by a blocker mounted so as to be inverted. The expansion valve is arranged laterally and communicates with a high-pressure chamber immediately downstream from the blocker and with a low-pressure chamber via a side passage. A device for mechanically controlling the blocker is provided in a chamber sealingly separated from the high-pressure chamber and from the low-pressure chamber. A flow selector in the form of a disc with a calibrated opening is provided in the low-pressure chamber, the disc engaging with a passage directly linked to the outlet of the device. The mechanical control device engages with a control pin of the disc.

摘要： The thermally activated pressure relief valve (10) has a piston (14) normally retained in a closed position and being movable to an open position in case the valve (10) is exposed to an abnormally high temperature. An elastic slotted spring sleeve (20) is disposed within a sleeve (18) of fusible material. In a non-activated state the fusible sleeve (18) maintains the spring sleeve (20) in a radially compressed condition wherein it has a smaller inner diameter effective to retain the piston (14) in the closed position. When the fusible sleeve (18) melts the spring sleeve (20) radially expands to a larger diameter permitting movement of the piston to the open position wherein it is partly received in the spring sleeve (20).

摘要： An electric generator comprising a rotor with permanent magnets, configured for rotating about a rotation axis; a stator comprising at least one magnetic yoke with arms extending axially inside or outside of the rotor so as to be adjacent to a radial inner or outer side, respectively, of the rotor; wherein the arms of the at least one magnetic yoke are circumferentially distributed so as to form a slot between each pair of adjacent arms, each slot and each arm showing a width. The widths of the arms and/or the widths of the slots have different values distributed along the circumference. The invention is also directed to a valve comprising the electric generator equipped with a turbine wheel for being driven by a flow of gas in the valve.

摘要： 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.
