<p>An apparatus (60) for dispensing gas stored in a highly pressurized container (61) and then refilling the container (61) with more gas. The apparatus includes a regulator (30) that in turn includes a first valve assembly (5, 6, 7, 8) on a first gas flow path to permit the flow of gas from the container (61) into the regulator (30) and to maintain a substantially constant output gas pressure or speed, regardless of the internal pressure of the highly pressurized gas container (61). The regulator (30) also includes a second valve assembly (2, 13, 17, 18, 19) on a second gas flow path to refill the container (61) with highly pressurized gas and to seal the second gas flow path at times when the container (61) needs not be refilled. The over-pressure relief mechanism (9, 10, 11, 12) of the regulator (30) releases gas from the highly pressurized container (61) in response to a condition where the internal pressure of the container (61) exceeds one and two thirds of the maximum internal pressure of the container (61).</p> |
