Abstract

resumo patente de invenção: "controle da variação de amplitude para pressurização". a invenção refere-se à pressurização de um volume (2) que necessita ter uma pressão de ar relativa, em comparação com uma pressão ambiente, em que a pressão do ar ambiente pode mudar rapidamente e com grande amplitude e em que o acesso ao ar pressurizado é limitado. isto é solucionado por um sistema meio aberto compreendendo dois reguladores paralelos (9) e (17) e dois ejetores (15) e (19) funcionando de acordo com um princípio de controle da faixa de ruptura. quando a diferença da pressão relativa do ar está acima do valor desejado do segundo regulador (17), somente o primeiro regulador e o primeiro ejetor funcionam. quando a diferença da pressão relativa do ar está abaixo do valor desejado do segundo regulador (17), ambos os reguladores (9) e (17) e ejetores (15) e (19) funcionam. dessa maneia a pressão dentro do volume (2) pode se adaptar rapidamente às mudanças na pressão do ambiente, sem vazar muito ar durante a condição estática.
