Abstract
A valve includes a valve case secured to a container that stores a pressurized fluid, and a valve pin moveable relative to the valve case and defining a fluid path in cooperation with the valve case. A seal separates the fluid path into an upstream portion communicating with inside of the container and a downstream portion communicating with outside of the container. The valve pin has a main passage always communicating with outside of the container, and a bypass passage. A valve pin adjuster, responsive to change in pressure acting on the valve pin within the container, shifts the valve pin between a first position where fluid communication between the main passage and the upstream portion of the fluid path is blocked to prevent the pressurized fluid from being discharged from the container, and a second position where fluid communication between the upstream and downstream portions of the fluid path is established through the bypass passage to allow the flow of the pressurized fluid from the container.
