Abstract:
A tubular pressure accumulator which is used, in particular, as a fuel distribution rail for a mixture-compressing, spark-ignited internal combustion engine includes a tubularly bent metal wall. In this way, longitudinal sides, which are assigned to one another, of tubularly bent metal wall are connected to one another through a weld. Furthermore, the tubularly bent metal wall has at least one design feature implemented by the machining of the flat metal wall and the bending of metal wall, which take place prior to the welding.
