Abstract
Patente de Invenção: <B>AMORTECEDOR DE PRESSãO DE TUBO PLANO PARA AMORTECIMENTO DE VIBRAçõES DE PRESSãO DE LìQUIDO EM CONDUTOS DE LìQUIDO"<D>. A invenção refere-se a um amortecedor de pressão de tubo plano (1) para amortecimento de vibrações de pressão de líquido em condutos de líquido, especialmente de vibrações de pressão de combustível em condutos de suprimento de combustível de veículos automotores, com ao menos uma câmara (24) longitudinal, cuja seção transversal é pequena relativamente a sua extensão longitudinal e da qual ao menos uma parede da parede de câmara (26), que encontra-se em comunicação operacional com o líquido, é elasticamente deformável por vibrações de pressão de líquido. A invenção prevê que, vista ao longo da extensão longitudinal da câmara (24), sua seção transversal altera-se continuamente ou escalonadamente.
