Abstract

DISPOSIÇÃO DE VEDAÇÃO E BOMBA COM UMA DISPOSIÇÃO DE VEDAÇÃO. A invenção refere-se a uma disposição de vedação para uma câmara de alta pressão (11), com um elemento de limitação (12) e um elemento terminal (13). O elemento de limitação (12) apresenta uma superfície de vedação externa (14) e o elemento terminal (13), uma superfície de vedação interna (15). A superfície de vedação externa (15) e a superfície de vedação interna (14) estão dispostas de tal modo que através de um contato das duas superfícies de vedação (14, 15) é obtida uma vedação da câmara de alta pressão (11). De acordo com a invenção, o elemento de limitação (12) está realizado de tal modo que devido a uma pressão na câmara de alta pressão (11), uma força na direção da superfície de vedação (interna (15) pode atuar sobre a superfície de vedação externa (14). Desse modo, também é obtida uma função de vedação quando o elemento terminal (13) se deforma, devido à pressão na câmara de alta pressão (11). A disposição de vedação de acordo com a invenção pode ser usada de modo particularmente vantajoso em bombas.
