2nd stage Cyclon 5000

This assembly is the second stage (model 1133) of the Poseidon Cyclon 5000 diving regulator. All dimensions are taken quite precisely (+/-0,02mm) from an actual instance, but be aware that they might differ to another one due to manufacturing tolerances. Especially the flexible diaphragms are difficult to measure. The names of the parts are according to a Poseidon Service Manual from 1999. The O-Ring names feature the current (2023) part numbers, their metric sizes and the outdated Poseidon part numbers used in the manual. The valve seat is placed on the recommended position to start the adjustment of the regulator.
