Abstract
A breathing regulator especially suited for use in scuba diving comprises an externally adjustable flow vane or deflector to redirect a portion of inlet high velocity air towards the diaphragm of a venturi initiated vacuum assist-type regulator configuration. The flow vane interrupts and redirects a selected portion of the air stream thereby balancing the low pressure area adjacent the diaphragm at a constant level throughout the breathing cycle. As a result, the diver can adjust his inhalation effort requirements to be constant throughout the breathing cycle.
