Abstract: A method for filling a compressed-gas container, in particular a compressed gas container in an airbag system, with a gas or gas mixture, or for producing a gas mixture in a compressed gas container. The filling is accomplished by introducing a gas mixture, or at least one gaseous component of the gas mixture, into a cooled compressed-gas container in the form of a gas or liquid-cooled gas.

Abstract: A method for filling a pressure vessel, for example an airbag system, with a gas or gas mixture. The filling is accomplished by cooling a pressure vessel, filling said vessel with at least one type of gas at a temperature which is higher than the boiling point thereof and closing the cold vessel. A pressure is produced in the filled and closed vessel by heating said vessel at an ambient temperature.

Abstract: The invention concerns a process respectively a device for filling a high pressure gas container (1), comprising the following steps: Supplying a liquefied or solidified first gas (2) into a gas container (1) while the gas container (1) is being cooled; stopping the cooling of the gas container (1) after the supplying step of the first gas; then introducing a gaseous second gas (3) into the gas container (1) and closing the gas container (1). The invention allows for a efficient, reproducible, reliable and economical filling of high pressure gas containers (1), in particular for airbag systems or for fuel cells, and allows to use conventional devices for introducing gases respectively closing gas containers that are not particularly adapted for low temperature respectively high pressure applications.

Abstract: In the method for filling a pressure vessel (1), in particular a pressure vessel in airbag systems, with a gas or gas mixture, one or more cryogenically solidified gases and optionally a cryogenically liquefied gas are introduced into a pressure vessel (1).

Abstract: The invention relates to a method for filling a compressed-gas container, in particular a compressed-gas container in an airbag system, with a gas mixture, or for producing a gas mixture in a compressed gas container. According to said method, a gas mixture or at least one gaseous component of the gas mixture is introduced into a cooled compressed-gas container in the form of a gas or liquid-cooled gas.

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.

Abstract: A process, an arrangement and a gas supply station for filling high pressure gas containers include supplying a liquefied or solidified first gas (2) from a gas supply station (13) through a thermally isolated filling tube (14) with a moveable tube head (15) to the high pressure gas container (1); as well as a process of batch filling of high pressure gas containers (1) with gas, wherein multiple gas containers (1) are cooled in parallel, which are filled sequentially using the process. The invention allows for fast, economical, reliable, reproducible and precise filling of high pressure gas containers, wherein a number of the known conventional devices that are not particularly suited for high pressure respectively low temperature appliances may still be used.

Abstract: The invention concerns a process, an arrangement and a device for filling a high pressure gas container (1) with liquefied gas, comprising the following steps connecting the gas container to a metering valve (17) and connecting the metering valve (17) to a first container (21) containing liquefied gas, wherein the first container (21) is positions above the gas container (1) at a geodetic height (H); opening the metering valve (17) and admitting the quantity of liquefied gas is supplied with the first container (21) into the gas container (1) at a hydrostatic pressure that corresponds to the geodetic height (H); closing the metering valve (17). As the hydrostatic pressure may be tightly controlled, the high pressure gas container (1) may be efficiently, reproducible, reliable and economically filled at a particularly high metering precision.

Abstract: The inventive method for filling a pressure vessel, for example an airbag system with a gas or a gas mixture consists in filling said vessel with at least one type of gas at a temperature which is higher than the boiling point thereof, closing the cold vessel and in producing a pressure in the filled and closed vessel by heating at an ambient temperature.
