Abstract
"DISPOSITIVO DE CONTROLE DE PRESSãO VARIáVEL". Trata-se de um sistema de válvula de controle que possui um alojamento que define uma entrada, uma saída e uma exaustão. Uma primeira passagem se estende entre a entrada e a saída e uma segunda passagem se estende entre a saída e a exaustão. O sistema de válvula de controle inclui uma primeira válvula disposta dentro da primeira passagem. A primeira válvula é móvel entre uma posição fechada e uma posição aberta. Similarmente, o sistema de válvula de controle inclui uma segunda válvula disposta dentro da segunda passagem. A segunda válvula é móvel entre uma posição fechada e uma posição aberta. Ademais, o sistema de válvula de controle inclui um circuito operador acoplado operavelmente ao alojamento, que produz uma pressão piloto em resposta a uma pressão de entrada. Um membro atuador é disposto deslizavelmente dentro do alojamento e móvel em resposta a um diferencial de pressão existente entre a saída e a pressão piloto. O membro atuador atua independentemente da primeira válvula e da segunda válvula, para proporcionar uma pressão rápida e o recurso da exaustão.
