<p>A pressure relief device having a housing including an inlet, an outlet, a nd an inner wall defining a bore connecting the inlet and the outlet. The inlet is in communication with a fluid under pressure in a pressure vessel. The bore includes an inlet portion extending from the inlet toward the outlet, and an outlet portion extending from the outlet toward the inlet. The bore also includes a tapered portion connecting the inlet portion and the outlet portion. The inl et portion has a diameter which is less than the outlet portion's diameter. A plug is located in the bore and movable from a closed position, in which flow of flu id through the bore is blocked, to an open position, in which flow of the fluid through the bore is permitted in response to a pressure differential between the inl et and the outlet.</p> |
