Abstract

"COMPRESSOR ROTATIVO". Em um compressor rotativo, uma superfície periférica exterior (40) de um elemento de divisória (23) que é preso com firmeza a um invólucro (10) para dividir o interior da caixa (10) em um espaço de pressão de nível elevado e um espaço de pressão de nível baixo é dotada de um sulco periférico (42) para permitir a contração da caixa (10) em uma área de solda onde uma parte de tronco (11) e uma placa de extremidade (12) da caixa (10) são soldadas uma à outra. Em conseq³ência de tal arranjo, o elemento de divisória (23) é apertado com intensidade mediante a utilização de tal contração, desse modo incrementando não somente a capacidade de vedação entre o espaço de pressão de nível elevado e o espaço de pressão de nível baixo no interior da caixa (10) mas também impedindo uma queda na capacidade operacional durante a montagem e um aumento no custo.
