Abstract

<B>VáLVULA DE CONTROLE COM VEDAçãO AXIAL<D>. Um válvula de controle de duas vias para abrir seletivamente uma primeira passagem para uma segunda ou terceira passagem, em que é previsto um alojamento tendo uma abertura do corpo da válvula com parede lateral circular e uma porção de base que corta a primeira, segunda e terceira passagens; um corpo de válvula fixado dentro da abertura do corpo da válvula, e um pistão com um êmbolo na extremidade do mesmo disposto reciprocamente dentro do cilindro do pistão estendendo-se axialmente através do corpo da válvula, o pistão sendo recíproco para deslocar o corpo de válvula para fechar o cilindro do pistão e conseq³entemente a segunda passagem ou para deslocar a porção de base da abertura do corpo da válvula para fechar a terceira passagem.
