ABSTRACT:
An air flow regulator is provided which may be utilized in diving or scuba equipment. A diaphragm urges a pivoted leg assembly into pivoted motion and the latter, being coupled to a valving means, provides controlled passage of air to the user. A sloped, rolling contact is provided between the pivoted leg portion and a stationary mounting means therefor so that a variably positioned pivot point is provided along the longitudinal length of the leg portion as it experiences various degrees of pivoted movement whereby the leg portion provides correspondingly various degrees of mechanical advantage for moving the valve means of the assembly. The various mechanical advantages correspond to the various degrees of effort required for different selected valve openings so that the same amount of user effort is necessitated for all positions of valve opening.
