Abstract

"RETENTOR DE VEDAçãO COM ELEMENTOS DE VEDAçãO METáLICOS PARA ACOPLAMENTO HIDRáULICO SUBMARINO" Um retentor de vedação aperfeiçoado para um elemento de acoplamento hidráulico submarino, que utiliza vedações metálicas para manter a integridade do fluido, é descrito. As vedações metálicas da presente invenção são projetadas para criar uma barreira absoluta para o fluxo de fluido, ou utilizar um encaixe por pressão ou interferência para criar uma barreira para o fluxo de fluido para garantir a integridade do fluido entre o acoplamento hidráulico submarino e o ambiente fora do acoplamento hidráulico.
