Abstract

Patente da Invenção: "FLUTUADOR PNEUMáTICO PARAAVIõES LEVES E ULTRALEVES". O flutuador pneumáticoinventivo consiste em um forro exterior (5) que através de umaválvula (21) pode ser solicitado com ar comprimido. Em essênciapor sobre todo o comprimento do flutuador se estendem nervuras(6) que são unidas ao longo das linhas (1) ao forro exterior (5) e, porum lado, repartem o interior do flutuador em câmaras (7)comunicantes entre si e, por outro, conferem ao flutuador ocontorno (14), estabilidade e resistência à flexão desejados. Asnervuras podem consistir em uma ou em várias camadas de tecidopouco dilatável ou em folhas de material plástico. Para a melhorada estabilidade direcional no funcionamento e para a proteçãocontra danificações do forro exterior (5), o flutuador apresenta umarégua de quilha (8) que consiste, por exemplo, em material plásticoe que é colada sobre o forro. Para o impedimento do efeito Coandasão instaladas duas réguas laterais (9) de igual maneira.
