Abstract

"DISPOSITIVO DE BOMBEAMENTO DE FLUIDOS". A presente invenção refere-se a um dispositivo de bombeamento de fluidos (50) compreendendo uma carcaça (20) formada por pelo menos uma porção de entrada de fluido (23, 23<39>) e pelo menos uma porção de saída de fluido (24) e pelo menos um atuador (30) disposto no interior da carcaça (20); a carcaça (20) sendo formada por pelo menos uma primeira e segunda porções (21, 22) dispostas paralelamente entre si e que se encaixam definindo um canal interno (10) que recebe pelo menos um atuador (30); o atuador (30) compreendendo uma primeira porção extrema (33) disposta engastada em uma região de engaste (29) da carcaça (20) e uma segunda porção extrema (34) livre voltada para a porção de saída de fluido (24); e o atuador laminar (30) sendo movimentável oscilantemente de modo a bombear o fluido em direção à porção de saída (24).
