<p>The device for compensation for the variations in pressure of the gaseous fluid flowing in a portion of main conduit is characterised in that it comprises a short additional piping 21 linking the said conduit portion 14 to a variable-volume capacity 205 delimited by a flexible membrane 203 and by a rigid shell 201 mounted on the said short additional piping 21 and supporting the flexible membrane 203 and in that it further comprises an elastic means 206, 210 acting on the said flexible membrane 203 in order to establish a predetermined datum pressure on the flexible membrane. Application to the compensation for pressure variations in a portion of conduit situated between a regulator - pressure reducer and a shut-off valve operating in all-or-nothing placed downstream from the regulator. <IMAGE></p> |
