The regulator housing comprises two spherical halves (1,2) with a circular outwardly folded edge (3,4). The halves are joined by vacuum soldering with a circular, folded steel membrane (5) inserted between the outwardly folded edges. The one spherical half (1) is provided with partly a centrally fitted nipple component (6) in which the high pressure adjuster is inserted to be activated by the membrane, and partly a second nipple component (8) to which the output line is connected. The other spherical half (2) is provided with a closed pipe component (9) through which, prior to closure, gas is introduced at such a pressure that the requisite membrane pressureis obtained. The second nipple component contains a nozzle the commencing opening of which is such that over-critical flow is obtained in the output line. |
