Abstract

"MéTODO E DISPOSITIVO PARA MANTER PRESSãO DE FLUIDO EM UM VOLUME DEFINIDO". A invenção refere-se a um método e a uma válvula de regulagem destinados a manter uma pressão de fluido dentro de um volume definido (3), e o registro simultâneo de descarga de fluido a partir do volume como um resultado de vazamento ou consumo. O fluido é fornecido a partir de uma válvula de regulagem de pressão (20) munida de um meio (5-7, 22-26) que se abre para o suprimento de fluido para o volume (3) quando a pressão dentro dele desce abaixo de um primeiro valor (Pl) e que impede o suprimento de fluido quando a pressão no volume (3) alcança um valor de pressão predeterminado (P2) que é substancialmente maior que o primeiro valor (Pl). Assim sendo, após cada abertura da válvula reguladora (20) ocorre um aumento distinto de pressão na saída de válvula. Este aumento de pressão é registrado como um pulso de pressão, e a freq³ência dos pulsos de pressão entregues é monitorada e utilizada como um meio de ocorrer vazamento e/ou consumo de fluido fornecido.
