Abstract

" REGULADOR DE PRESSãO DE SUCçãO, E, APARELHO PARA DRENAR FLUIDOS CORPORAIS". Caracterizado é um regulador de controle de pressão incluindo um alojamento, um elemento de vedação disposto dentro do alojamento, um elemento flexível e um mecanismo de solicitação. O alojamento inclui pelo menos uma abertura de entrada e pelo menos uma abertura de saída, cada abertura de entrada sendo acoplada de forma fluida a uma primeira fonte de pressão e cada abertura de saída sendo acoplada de forma fluida a uma segunda fonte de pressão, as primeira e segunda fontes de pressão estando em diferentes pressões. O elemento flexível se estende entre a superfície externa do elemento de vedação e a superfície interna do alojamento de modo a formar um limite de pressão entre as mesmas e para dividir o interior do alojamento nos primeiro e segundo compartimentos. O mecanismo de solicitação, que responde à pressão dentro do segundo compartimento, age no elemento de vedação de forma que o elemento de vedação esteja em uma de uma posição aberta, quando a pressão do segundo compartimento é superior a um valor de pressão predeterminado, ou uma posição fechada, quando a pressão do compartimento é igual ou inferior ao valor de pressão predeterminado. Uma parte do alojamento em comunicação fluida com a segunda fonte de pressão, também inclui um mecanismo para restringir o fluxo de fluido para ou do segundo compartimento de forma que a pressão do segundo compartimento mude quando o fluxo de fluido em qualquer direção ocorre por um período de tempo superior a um período de tempo predeterminado e permanece efetivamente inalterada quando tal período de fluxo de fluido é inferior ao período de tempo predeterminado. Em uma modalidade mais particular, a segunda fonte de pressão e uma fonte de sucção e o regulador é um regulador de pressão de sucção.
