Abstract

"VáLVULA DE TRêS-VIAS ELETRICAMENTE CONTROLADA". Referente a uma válvula de três vias (1) com controle elétrico compreendendo um corpo de válvula (2), dentro do qual são providos uma cavidade central (3) e um respectivo primeiro, segundo e terceiro dutos (4, 5, 6) de conexão, adaptados para colocar a cavidade central (3) em comunicação com a atmosfera, e um membro (7) obturador montado para mover-se dentro da cavidade central (3) entre uma primeira posição de operação, na qual o membro (7) obturador está disposto para fechar a entrada do primeiro duto (4) de modo a obstruir este primeiro duto (4) de maneira estanque e colocar o segundo duto (5) em comunicação exclusiva com o terceiro duto (6), e uma segunda posição de operação na qual o membro obturador (7) está disposto para fechar a entrada do terceiro duto (6) para obstruir este terceiro duto (6) de modo estanque e colocar o segundo duto (5) em comunicação exclusiva com o primeiro duto (4); o membro obturador (7) sendo de formato esférico e independente de qualquer outro membro da válvula (1) de modo que pode mover-se livremente dentro da cavidade central (3); a cavidade central (3) sendo formada de tal modo que o membro obturador (7) é forçado a engastar simultaneamente as entradas (4a, 6a) do primeiro e do terceiro dutos de conexão (4, 6), mas obstrui, entretanto, somente um dos primeiro e terceiro dutos de conexão (4, 6) de um modo estanque.
