The inventive method for filling a pressure gas container from a gas source pressure with a high pressure for a predetermined filling time selected or calculated prior to filling and at a determined temperature consists in forming a connection in the form of a fluid passage between the source and container, in carrying out a plurality of the passage opening-closing sequences during predetermined sub-intervals of the predetermined filling time, wherein the curve of a current pressure in the container follows, according to a time, a theoretical straight line linking the pressure measured prior to filling and after thereof during the filling time, the predetermined filling time is subdivided into a number of the time sub-intervals ranging from two to several hundreds and having respective determined duration, preferably ranging from 5 and 20 seconds.

Method and device for filling pressure gas containers

The invention concerns a method for filling pressurized gas tanks, characterized in that the filling process is interrupted when the input pressure reaches a maximum filling pressure, the maximum filling pressure in the cylinder being calculated to match the most serious of the two following conditions: nominal filling capacity or design temperature of the cylinders.
