Abstract

There is provided a high pressure sealing apparatus including: a top adapter including a packing receiving recess having an inverted V-shaped section; a bottom adapter including a packing supporting wall having an inverted V-shaped section; packing members each having an inverted V-shaped section, and interposed between the top adapter and the bottom adapter; and backup rings each having an inverted V-shaped section, and alternately overlapped with the packing members. The packing members are made of hard synthetic resin. A deformation allowing gap is formed on at least two facing walls of a top wall or a bottom wall of the packing member, and a bottom wall of the top adapter, a top wall and a bottom wall of the backup ring, or a top wall of the bottom adapter to be closed owing to compaction force in an axial direction X.
