  • Vented safety vessel with acoustic trap for rarefaction waves
    Patent number: 5077018
    Abstract: An acoustical wave trap is combined with the rupture disc or relief valve used in vessels for storing potentially explosive materials. The acoustical wave trap operates to substantially reduce the magnitude of the rarefaction wave produced within the vessel when the rupture disc or relief valve opens, and thereby simplifies the pressure relief requirements.
