An apparatus and method for high pressure gas filling of gas cylinders is disclosed. The apparatus includes an elongated filling tube for a pressurized gas cylinder having a valve regulator/fitting sealed in an opening at one end of the gas cylinder, the elongated filling tube extending within the cylinder and being attached at one end to the valve regulator/fitting. The elongated filling tube is provided with longitudinally spaced transverse openings along the length thereof to facilitate intermixing of gases injected into the cylinder under pressure. The method of high pressure gas mixing within a pressurized cylinder includes the steps of injecting a predetermined volume of a first gas under a predetermined pressure into the cylinder, and injecting a remaining volume of at least one other gas under a greater predetermined pressure into the cylinder, while also intermixing the molecules of the first and the at least one other gas together throughout the cylinder in order to produce a desired gas mixture within the pressurized cylinder. |
