Abstract
"COMPRESSOR DE VOLUTA". Um compressor de voluta tem uma estrutura nas extremidades de pelo menos um de seus envoltórios, que reduz a força que separa os envoltórios de voluta. Em uma concretização, a estrutura inclui rebaixos formados na extremidade, de forma de fluido a baixa pressão é sangrado através da superfície entre a extremidade e a oposta da voluta. O fluido a baixa pressão reduz a força de separação entre o envoltório de voluta. Paredes de separação podem ser formadas para definir rebaixos separados. Em uma segunda concretização, um fluido à pressão intermediária é sangrado para um sulco. Novamente, a baixa pressão reduz o componente da força de separação contra o envoltório de voluta. Esta invenção é particularmente valiosa para os tipos de envoltórios de voluta que têm envoltórios estreitos.
