Abstract

"CONJUNTO DE VáLVULA TENDO ANéIS RETENTORES FLUTUANTES". Conjunto de válvula (300) incluindo um alojamento de válvula (301) que tem uma passagem de fluido (302) se estendendo através dele. Um elemento de válvula (325) está localizado na porção de câmara interna (307) e é móvel entre uma posição fechada, na qual a passagem de fluido está bloqueada, e uma posição aberta, na qual a passagem de fluido não está bloqueada. Um primeiro e um segundo conjuntos de anel retentor substancialmente anular (440, 441) também estão localizados na porção de câmara interna (307) e posicionam, de forma rotativa, o elemento de válvula (325) dentro da porção de câmara interna (308). O primeiro e o segundo conjuntos de anel retentor (440, 441) provêem um primeiro e um segundo selos de fluido (370, 375) entre o elemento de válvula (325) e a superfície de câmara interna (308) na primeira e na segunda extremidades da porção de câmara interna (307), respectivamente. Cada um dentre o primeiro e o segundo conjuntos de anel retentor (440, 441) inclui um anel retentor flutuante e uma pluralidade de elementos de vedação (370 a 376). Os anéis retentores flutuantes (440, 441) são móveis em relação ao elemento de válvula (325), à superfície de câmara interna (308) e às paredes de entrada e de saída.
