Abstract : A diving helmet exhaust regulator valve maintains helmet pressure substantially constant in a push-pull system wherein breathing gas is supplied under pressure (push) at a constant rate and respired gas is exhausted to a low pressure (pull) conduit for return a regenerator. The regulator valve is characterized by a throttling valve member operated by a piston that is acted upon by ambient sea pressure and helmet pressure independently of pressures in the upstream exhaust passages, or of exhaust flow rate.
