Abstract
The system of the present invention reduces hydrostatic imbalances acting on the diaphragm of a diver's open-circuit breathing apparatus' regulator. In general, the system applies a flexing force to the diaphragm based on the position of the diver's head relative to gravity when the mouthpiece is in the diver's mouth. The system can be realized by a simple mechanical pendulum assembly attached to the regulator.
