Release valve

A storage container for a fluid under pressure, wherein the storage container comprises a release valve for releasing fluid from the storage container for inflating an inflatable structure, wherein the release valve comprises:

• a housing comprising an inlet coupled to the storage container, and an outlet;
• a flow chamber disposed within the housing and forming part of a flow path from the inlet to the outlet;
• a valve member configured to move to a release position to permit fluid to flow from the inlet to the flow chamber;
• and
• an actuator and a biasing device, wherein the actuator and the biasing device are disposed in the flow chamber, the actuator configured to move through the flow chamber from an unactuated position to an actuated position to move the valve member to the release position,
• wherein the biasing device comprises a spring acting on the actuator, via a projection extending from the actuator, to bias the actuator to the actuated position;
• and
• wherein the projection is in the form of an annular plate and comprises one or more flow holes to permit fluid to flow therethrough to the outlet in at least the actuated position of the actuator.
