Abstract

"VáLVULA PIEZO". A presente invenção refere-se a uma válvula piezo (1), que contém uma unidade de transdutores (8), que dispõe de dois transdutores (12, 13) acionáveis em movimentos de desvio em sentido contrário. Os transdutores (12, 13) estão ligados fixamente entre si em uma região extrema da unidade de transdutores (8) formando um segmento de suporte (14) em comum. A unidade de transdutores (8) está montada pivotável relativamente à caixa de válvula (2). Ao menos um transdutor (12, 13) serve como transdutor de controle uma abertura de válvula (25) a ele associada, sendo que o outro transdutor mediante aplicação de uma tensão de ativação pode ser protendido contra uma área de apoio (44) disposta em sua via de desvio, para produzir por exemplo um aumento de via de ajuste do outro transdutor.
