Abstract:

The housing is attachable to a high pressure fluid containing structure. A piston is provided within the housing, with the piston having a closed position and an open position. The closed position blocks an outlet vent of the relief device, with the open position allowing high pressure fluid to escape through the vent. The piston is biased toward the open position by the high pressure fluid, but is held in the closed position by a slide. The slide has a first position and a second position, with the first position holding the piston in the closed position. A spring biases the slide toward a second position, with a eutectic mass resisting movement of the slide to the second position. The eutectic mass is selected to have a melting point matching a maximum design temperature for the high pressure fluid containing structure. Should the eutectic mass melt, the high pressure fluid escapes.
