Abstract

resumo patente de invenção: "palheta oca e método de produção associado". uma palheta oca consistindo em uma parte principal (1), da qual a cavidade (4) é fechada por uma cobertura (5), é produzida pela expansão da parte principal (1) com relação à cobertura (5), por exemplo, por meio de expansão térmica diferencial, então pela colocação da cobertura (5) no fundo (11) da abertura (8) da cavidade (4), antes de permitir a parte principal (1) fechar novamente, fechando um encaixe entre uma saliência (6) no fundo da cobertura (5) e um alargamento (10) no fundo da abertura (8). isto evita desvantagens relacionadas ao uso de solda, cola ou até mesmo de peças de montagem.
