Abstract

"DISPOSIçãO DE VEDAçãO". A presente invenção refere-se a uma vedação baseada em copo em U de uma haste, o corpo básico do copo em U 3 é reentrado em relação a um formato de seção transversal quadrado na região de uma beira externa radialmente interna 18 no lado de baixa pressão de modo a obter um espaço 17 entre o copo em U 3 e a abertura, isto é, a abertura de passagem 16 de uma lacuna de vedação 15, levando para dentro de uma ranhura retangular 4 guiando o copo em U 3. Este espaço 17 permanece pelo menos parcialmente também quando da pressurização de modo que o copo em U 3 completamente permanecerá na ranhura 4 quando da pressurização e não seja extrusado para dentro da lacuna de vedação 15. Isto de forma considerável reduz o desgaste do copo em U 3.
