Abstract

"DISPOSITIVO DE VáLVULA DE GARGANTA". A presente invenção refere-se a um corpo principal de válvula (10) que possui uma parte de tambor ampliada (13) formada em uma extremidade de uma parte de eixo (12), a parte de tambor (13) transmitindo uma força de operação de ajuste de regulagem a partir de um exterior para a parte de eixo. Uma mola de torção (27) é colocada entre uma tampa (28) que cobre o corpo principal de válvula (10) e um corpo de garganta (8) a partir do lado da parte de tambor (13) e a parte de tambor (13). A mola de torção (27) é de um tipo de mola em espiral de compressão que força a parte de tambor (13) em uma direção de fechamento de válvula. A mola de torção (27) está disposta concentricamente ao corpo principal de válvula (10). A mola de torção (27) possui duas extremidades (272), (271) dobradas diametralmente para dentro de uma parte em espiral da mola de torção (27). As duas extremidades (272), (271) são engatadas em fendas (284), (131) formadas na tampa (28) e na parte de tambor (13), respectivamente. A mola de torção é deste modo travada em posição, sendo impedida de girar.
