A compressed gas tank for a motor vehicle includes a metallic gas container having opposite container walls which are constructed with a profiling to increase rigidity, and at least one tie element extending across the gas container. The profiling is realized by stamping a plurality of wall portions from the plane of the container walls to assume a convex and/or concave configuration.

Compressed gas tank for a motor vehicle

An apparatus for hydraulic high-pressure forming of a sheet, the apparatus having a top tool and a bottom tool as well as at least one pressure generating unit arranged between the press ram of a mechanical press and the top tool and uses a pressurized medium from the pressure generating unit as a working fluid for hydraulic preforming of the sheet. Contact faces of the tools directly engage with the sheet surface along the clamping area thereof and act to seal off the forming area that are subjected to the working fluid solely by contact sealing.
