Abstract

bomba a seco para gases e conjunto de uma pluralidade de bombas a seco para gases. a presente invenção refere-se a bomba a seco para gases compreendendo primeiro rotor (1) compreendendo primeira porção de ressalto (1a) e primeiro parafuso (1b), bem como segundo rotor (2) compreendendo segunda porção de ressalto (2a) e segundo parafuso (2b). um invólucro delimita um volume interno em que estão localizados juntos o primeiro e o segundo parafuso (1b, 2b) e a primeira e a segunda porção de ressalto (1a, 2a). cada um dentre o primeiro e segundo parafuso (1b, 2b) compreende uma roscagem invariável ao longo de seu comprimento. o primeiro e o segundo rotor (1, 2) giram em direções opostas e estão localizados em configurações sucessivas. em uma primeira configuração dos rotores, a primeira e a segunda porção de lóbulo (1a, 2a), uma porção do primeiro parafuso (1b), uma porção do segundo parafuso (2b) e o invólucro juntos delimitam uma câmara (30) que é fechada. em uma segunda configuração dos rotores, a câmara (30) tem uma capacidade menor do que na primeira configuração. em uma terceira configuração dos rotores, a câmara (30) é deslocada completamente no primeiro e no segundo parafuso (1b, 2b) e isolada das porções de ressalto.
