Electrical control for inflating valve for containers for compressed liquefied or dissolved gas

Abstract

An electrical control device for an inflating valve for containers for compressed, liquefied or dissolved gas with a cylindrical plug of fusible non-conductive material in which is embedded a helically wound electrical resistor formed as a cylinder having an axis substantially parallel to the plug axis and adapted to be connected to an electrical source. The plug is maintained in the inflating valve by a sleeve provided with a cavity and radial openings. Upon closing of the electrical circuit, the resistor heats and melts the plug, the central portion of which escapes towards the upper portion of the cavity opening to open a passage between the port connected to the container and the discharge port of a rotatable fitting surrounding the inflating head. The present invention can be used advantageously to control the discharge of a gas contained in a container in a pneumatic capacity and especially an inflatable lifeboat.
