Abstract

<B>"SERVOVáLVULA, EM ESPECIAL VáLVULA DE FECHAMENTO AUTOMáTICO OU CIRCULADOR DE PRESSãO"<D>. Numa servoválvula com um elemento de fechamento da válvula principal relativamente móvel em relação ao assento da válvula principal, que com uma extremidade pode ser trazido para uma posição de abertura e fechamento em relação ao assento de válvula principal, com uma câmara de descarga compreendendo a outra extremidade, um canal compensador apresentando um bocal compensador entre a tubuladura de afluência da válvula e a câmara de descarga, e um dispositivo de estrangulamento, de encontro a uma força de tensão, possível de ser movimentado para uma posição redutora do corte transversal de acesso do bocal compensador, dispositivo este que responde à pressão diferencial entre a câmara de descarga e a região situada a montante diante da válvula principal, propõe-se para o aperfeiçoamento, que o dispositivo de estrangulamento esteja gradativamente apoiado com intensidade variada pela força de tensão contra a pressão diferencial, de tal maneira, que na primeira região de estrangulamento sob pequena ou nenhuma pressão diferencial o dispositivo de estrangulamento é mantido por uma mola de carga leve na maior região de abertura, enquanto que sob grande pressão diferencial a mola de carga leve alcança um esbarro, e o estrangulamento restante é determinado pela mola de carga pesada.
