Abstract: The invention relates to a production device for additively manufacturing three-dimensional components by the layer-by-layer application of a construction material by means of at least one coating unit and spatially selective solidification of a construction material by means of at least one irradiation unit, comprising a process chamber having at least one heat-reflecting apparatus, in particular heat-reflecting layer, which shields at least one portion of a surface within the process chamber.

Abstract: The present invention relates to aluminium alloys in powder form having a content of at least two elements M from the group comprising Cr, Fe, Ni and Co and at least one element N from the group comprising Ti, Y and Ce, the alloy having a total amount of elements M in the range of 1 to 16 wt %, a total amount of elements N in the range of 0.5 to 5 wt % if the aluminium alloy contains Ti or Ce, and 1 to 10 wt %, if the aluminium alloy contains Y. Such aluminium alloys can be used in additive manufacturing processes, such as selective laser melting, to produce high-strength three-dimensional objects which can be used, for example, in engines for automobiles. The present invention further relates to processes and apparatuses for manufacturing three-dimensional objects from such aluminium alloys, processes for manufacturing such aluminium alloys in powder form, three-dimensional objects manufactured from such aluminium alloys in powder form, and specific aluminium alloys.

Abstract: A fuel injection valve for arrangement in a combustion chamber (40) of an internal combustion engine has a nozzle support with a nozzle body (30) disposed thereon in fixed fashion by way of a nozzle clamping nut (20), the nozzle body designed to protrude into the combustion chamber (40) and being provided for holding a nozzle needle, and at least one annular combustion chamber sealing element (50) with an upper support surface (60) facing the nozzle clamping nut (20) and a lower support surface (70) facing the combustion chamber (40), the lower surface surrounding the nozzle body (30) and being provided for sealing the nozzle support off from the combustion chamber (40). At least one additional sealing element (80) is provided for sealing the nozzle body (30) in the area of the nozzle clamping nut (20).
