ABSTRACT:
The regulator second stage for scuba incorporates a semi-balanced valve mechanism of high flow capacity which operates without significant influence from friction. The compression spring is suspended between two axially opposed pins to avoid friction producing contact with the housing walls. The valve mechanism is suspended between a dynamic seal and a lever assembly to avoid friction producing contact with the housing walls. The valve controlling lever rotates a ball bearing and collar mechanism in which ball bearings cooperate with notches to provide high mechanical advantage with very low friction. The diaphragm and exhaust valve cooperate to provide stable interaction which conserves breathing gas during all orientations of the regulator second stage.
