Abstract
A deflector has a ring attached at a first end to a pressurized vessel and around the sealed opening in the vessel. Rods project from a second end of the ring and a cover is mounted on the rods with springs holding the cover over the second end of said ring. Either the ring or the cover has an aperture therethrough an exhaust tube has one end located to receive fluid flowing through the aperture. When a small leak occurs at the sealed opening, escaping fluid flows through the exhaust tube and when the flow of escaping fluid is too great for the exhaust tube to handle, the cover slides away from the tube creating a larger passage through which the fluid can flow.
