Embodiment Construction

[0054] FIG. 1 schematically shows a two-step method for filling a high-pressure gas container 1 with a first gas 2 and a second gas 3 using a supply unit 7 for supplying the gas container 1 with a first gas 2 and an introduction unit 9 . Gas 2 , the introduction unit 9 is used for introducing a second gas 3 into the gas container 1 . The gas container 1 comprises a container body 26 for receiving the first gas 2 and the second gas 3 and connected to the auxiliary valve 5 . The gas container 1 is connected to a cooling tank 4 containing a third gas 6 which is liquefied in order to pre-cool the gas container 1 to 86°K. The third gas 6 is liquid nitrogen, which is kept at a low pressure in the cooling tank 4 so as to achieve 86°K in the cooling tank 4 . This precooling is carried out using a precooling unit 24 which immerses the gas container 1 at least partially in the cooling tank 4 . The gas container 1 is then conveyed by means of the conveying mechanism 12 to the supply un...

Abstract

The invention concerns a high pressure gas container (1) with a container body (26) for storing gas and at least one first valve (27) for discharging the stored gas, characterized by further comprising an auxiliary valve (5) for introducing the gas into the container body (26) and for temporarily closing the container body (26) until the container body (26) is sealed permanently, wherein the first valve (27) and the auxiliary valve (5) are in fluid connection with the container body (26). The invention also concerns a process for filling a high pressure gas container (1) having a container body (26) for storing gas, at least one first valve (27) for discharging the stored gas and an auxiliary valve (5) wherein the first valve (27) and the auxiliary valve (5) are in fluid connection with the container body (26), comprising the following steps: The gas is introduced into the container body (26) through the auxiliary valve (5), the auxiliary valve (5) is at least temporarily closed, the auxiliary valve (5) is sealed permanently. The invention allows for reliable, economical, reproducible and precise filling of high pressure gas containers using a conventional sealing apparatus without the need of its adaptation to either high pressure or low temperature appliance.

Description

technical field [0001] The invention relates to a high-pressure gas container having a container body for storing gas and a method for filling high-pressure gas having a container body for storing gas and at least one first valve for discharging the stored gas method of the container. Background technique [0002] For cold-filled pressure vessels, according to DE 10107895, the filling gas is cooled before it is introduced into the pressure vessel, wherein the pressure vessel is sealed in a pressure-tight manner upon completion of the filling process. The pressure inside the pressure vessel rises rapidly as the gas heats up. [0003] According to DE 19817324, a lightweight tank made of chrome-nickel steel liner inside a fibre-reinforced shell is filled with fuel gas, wherein the fuel is introduced in the form of a cryogenic liquid and stored at a pressure above 300 bar. [0004] According to WO 2005 / 043033, a pressure vessel such as an airbag system is filled with a gas or ...
