Abstract
turbina de geometria variável - é descrita uma turbina de geometria variável compreendendo: uma roda de turbina montada para rotação em torno de um eixo geométrico da turbina dentro de um alojamento. o alojamento define uma entrada anular envolvendo a roda de turbina e definida entre primeira e segunda paredes laterais de entrada. uma camisa cilíndrica é axialmente móvel através da entrada anular para variar o tamanho do caminho de fluxo de gás através da entrada. a entrada anular é dividida em porções axialmente adjacentes por pelo menos um defletor anular é axialmente espaçado da primeira e segunda paredes laterais de entrada. paletas de entrada estendem-se axialmente através de pelo menos duas das ditas porções anulares definidas por todo ou qualquer defletor, de maneira a dividir a dita entrada anular em pelo menos duas passagens de entrada axialmente deslocados. a configuração das paletas de entrada que estendem-se até uma das porções de entrada difere da confuguração das paletas de entrada que estendem-se até uma outra das porções de entrada e o diâmetro interno da camisa é maior que o diâmetro externo das passagens de entrada.Variable geometry turbine - A variable geometry turbine is described comprising: a turbine wheel mounted for rotation about a turbine geometry within a housing. the housing defines an annular inlet surrounding the turbine wheel and is defined between first and second inlet sidewalls. A cylindrical liner is axially movable through the annular inlet to vary the size of the gas flow path through the inlet. the annular inlet is divided into axially adjacent portions by at least one annular deflector is axially spaced from the first and second inlet side walls. inlet palettes extend axially through at least two of said annular portions defined by any or all of the deflector so as to divide said annular inlet into at least two axially displaced inlet passages. The configuration of the inlet palettes extending to one of the inlet portions differs from the confuguration of the inlet palettes extending to one of the inlet portions and the inner diameter of the jacket is greater than the outer diameter of the inlet passages. .
