Title: Eliminating Chatter in the MK 24 Full Face Mask By Adjusting Demand Lever Free Play and Inhalation Cracking Pressure.
Author: Crepeau, LJ
Abstract: The MK 24 full face mask (FFM) is configured to support MK 16 MOD 0 UBA decompression dives and SEAL delivery vehicle (SDV) transits. During certification testing at depths shallower than 15.3 msw (fsw) the FFM produced chatter upon inhalation in the open circuit mode, apparently due to newly-designed second stage regulator poppet valves and demand levers.
