  • Dynamic sealing device for high-temperature and high-pressure operation
    Patent number: 4004443
    Abstract: A pressure-tight assembly which can constitute a dummy block for an extension ram is made up of two coaxial components arranged in spaced relation to accommodate at least one peripheral seal. One component has a small flat bearing surface extending at right angles to the axis and the other component has a bearing surface which is inclined to the axis. The resultant of the forces exerted on the seal which is imprisoned between said bearing surfaces causes preferential creep deformation of the seal towards the exterior of the assembly.
