Abstract
A pressure regulator and safety valve assembly comprises pressure regulating means and safety valve means. The pressure regulating means is so coupled to the safety valve means that the pressure at which the safety valve means opens varies independence upon the setting of the pressure regulating means. The safety valve means includes a safety valve member mounted for movement relative to a static surface between a closed position in which the safety valve member seals against the static surface and an open position in which the safety valve member is spaced from the static surface.
