Pressure vessel or rocket motor has annular casing segments inside which annular rubber seals are mounted, one of which has slit dilated by pressurized gas to form pressure seal
Pressure vessel or rocket motor has annular casing segments inside which annular rubber seals are mounted, one of which has slit dilated by pressurized gas to form pressure seal
The pressure vessel comprises annular casing segments (144, 146). Annular rubber seals (190, 200) are mounted on the inside of each segment. One seal (190) has a slit (192) which separates a flexible section, which fits against the second seal, from the remainder of the ring. The pressurized gas in the vessel dilates the slit and forms a pressure seal between the two rings. Reinforcing pockets (220) are embedded in the rubber of the two rings. An Independent claim is included for a rocket motor constructed as described above.
