Abstract

é revelada uma unidade de acionamento de válvula (1). a unidade de acionamento de válvula inclui um primeiro fio sma (10a) e um segundo fio sma (10b), em que o primeiro fio sma (10a) e o segundo fio sma (10b) podem ser alternativamente ativados. a unidade de acionamento de válvula inclui ainda um elemento pivotante (12), em que o elemento pivotante (12) é articulável colocado em torno de um eixo do elemento pivotante (a), o elemento pivotante (12) incluindo um acionador de válvula (13), em que o acionador de válvula (13) é colocado a uma distância do eixo do elemento pivotante. o primeiro (10a) e segundo (10b) fio sma são acoplados ao elemento pivotante (12) de tal modo que uma ativação do primeiro fio sma (10a) faz com que o elemento pivotante (12) gire em uma primeira direção e uma ativação do segundo fio sma (10b) faz com que o elemento pivotante (12) gire em uma segunda direção, em que a segunda direção é oposta à primeira direção. o acionador de válvula (13) é projetado para engatar de forma removível um acoplador do acionador de válvula (313) de uma unidade de válvula (31), de tal modo que, no estado engatado, um giro do elemento pivotante (12) é transmitido ao acoplador do acionador de válvula (313) através do acionador de válvula (13).
