Abstract

turbina de geometria variável - é descrita uma turbina geometria variável que compreende uma roda de turbina montada para rotação em torno de um eixo geométrico da turbina dentro de um alojamento, o alojamento definido uma entrada anular envolvendo a roda de turbina e definida entre primeira e segunda paredes laterais de entrada; e uma camisa cilíndrica axialmente móvel através da entrada anular para variar o tamanho do caminho de fluxo de gás através da entrada axialmente deslocadas por duas ou mais paredes de passagem de entrada dispostas entre a primeira e segunda paredes de entrada.
