Abstract

MéTODO E DISPOSITIVO PARA CONTROLAR PRESSãO DE CONTROLE Trata-se de um método para regular a pressão de controle de um objeto (1") regulado por controle de pressão, pelo que a pressão de controle (p) e, conseqüentemente, a ação do objeto são reguladas por meio de uma unidade de controle (1) e uma disposição de válvula (1<39>). O método distingue-se especificamente pelas etapas de - medir a pressão de controle atual (p), a pressão de controle real, por meio de um sensor de pressão (4); - a unidade de controle (1) comparando a pressão de controle atual com a pressão de controle desejada (p<39>) correspondente à ação desejada do objeto; - regular a pressão de controle real, com base nos resultados da comparação, no sentido da pressão de controle desejada por meio de pelo menos uma válvula de aumento de pressão (5) do tipo liga/desliga e pelo menos uma válvula de diminuição de pressão (6) do tipo liga/desliga. A invenção refere-se também a um dispositivo para regular a pressão de controle de um objeto regulado controlado por pressão.
