Abstract: The pressure regulator is threadable onto the neck of a tank of gas under pressure that has a plug mounted in the neck and a rupturable disk blocking fluid flow through a plug bore. The main body includes a central reduced diameter portion extendable into the plug bore without rupturing the disk when the regulator is threaded to the neck, but when further threaded, ruptures the disk. The combination of the main body and a cap have a bore extending therethrough which opens to the tank interior when the disk is ruptured and to the regulator outlet. A piston is mounted in the body and cap bore that blocks fluid flow through the last mentioned bore when the pressure at the outlet is at or above a preselected level but permits flow therethrough when the outlet pressure is below the preselected level.

Abstract translation: 压力调节器能够在压力下的气体罐的颈部上螺纹连接，该罐具有安装在颈部中的塞子，并且可破裂的盘阻挡流体流过塞孔。 主体包括一个中心缩小的直径部分，当中的调节器被拧到颈部时可延伸到插塞孔中，而不破坏磁盘，但是当进一步螺纹化时，会破坏磁盘。 主体和盖的组合具有延伸穿过其中的孔，当盘破裂并且到调节器出口时，该孔通向罐内部。 当出口处的压力处于或高于预选水平时，活塞被安装在主体和盖孔中，以阻止流过最后提到的孔的流体，但是当出口压力低于预选水平时允许流过其中。
