ABSTRACT:
A safety valve for attachment to a gas cylinder. It has a body rigidly attachable to the port of a gas cylinder, with an inlet and an outlet. A valve between the inlet and outlet is held open by a fragile stem that is maintained in tension. When sufficient bending forces are exerted on the safety valve the stem breaks, its parts move apart from one another, and the safety valve closes.
