Abstract

Die Erfindung betrifft eine Vorrichtung mit einem Festkörper (2;12;22;30), einer in den Festkörper (2;12;22;30) eingebrachten, mit Innendruck beaufschlagten Bohrungsverschneidung (3,4,5,6;13,14,15;23,24,25,26;31,32,33,34,36) und außen am Festkörper (2;12;22;30) derart angeordneten Druckerzeugungsmitteln (1,7;10,11,16,17;20,21;35,37,38), dass diese in den Festkörper (2;12;22;30) eine Spannung einbringen, die der von dem Innendruck in der Bohrungsverschneidung (3,4,5,6;13,14,15;23,24,25,26;31,32,33,34,36) erzeugten Spannung entgegenwirkt, wobei die spannungsmindernde Kraft des Druckerzeugungsmittels (1,7;10,11,16,17;20,21;35,37,38) senkrecht zu derjenigen Ebene, die von den sich schneidenden Bohrungen (4,5,6;13,14;23,24,25;31,32,33) gebildet wird, auf den Festkörper (2;12;22;30) einwirkt.
