Abstract
"SISTEMA DE VáLVULA DE CONTROLE E MéTODO DE FORNECER MEMóRIA DE ESTADO DE VáLVULA NORMAL E ESTADO DE VáLVULA COM DEFEITO". Uma válvula dupla para controlar uma ferramenta de máquina tem uma memória de tal modo que quando a válvula está em seu estado não acionado normal e o fornecimento de ar de entrada é ciclado (por exemplo, girado de ligar para desligar ou de desligar para ligar), então a válvula permanece no estado não acionado (isto é, pronto para funcionar) . Quando a válvula está em um estado com defeito (por exemplo, posição intermediária) e o fornecimento de ar de entrada é ciclado, então a válvula permanece no estado com defeito. A memória é obtida por uma condição equilibrada dos elementos móveis de válvula quando na posição não acionada normal e uma condição não equilibrada ou travada quando na posição intermediária ou com defeito.
