ABSTRACT:
An automatic valve for inflating an inflatable article, includes a pin for piercing an operculum seal of a container for a compressed gas, a spring for urging the pin in a first direction to pierce the operculum seal of a compressed gas container, an arming mechanism for causing movement of the pin against the spring into an armed position and a latching mechanism including a pressurizable compartment for latching the pin in the armed position. The latching mechanism is arranged so as to release the pin on release of pressure of the pressurizable compartment, and a release mechanism for causing the release of pressure from the pressurizable compartment on immersion of the valve in water.
