High pressure gas container with an auxiliary valve and process for filling it

Abstract

A high pressure gas container with a container body for storing gas and at least one first valve for discharging the stored gas, further includes an auxiliary valve for introducing the gas into the container body and for temporarily closing the container body until the container body is sealed permanently, wherein the first valve and the auxiliary valve are in fluid connection with the container body. A process for filling a high pressure gas container having a container body for storing gas, at least one first valve for discharging the stored gas and an auxiliary valve wherein the first valve and the auxiliary valve are in fluid connection with the container body, includes the following steps: The gas is introduced into the container body through the auxiliary valve, the auxiliary valve is at least temporarily closed, the auxiliary valve is sealed permanently.
