Abstract
turbina de geometria variável - é descrita 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 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; em que a entrada anular é dividida em uma primeira porção de entrada anular e uma segunda porção de entrada anular axialmente deslocada da primeira porção de entrada, paletas de entrada que estendem-se axialmente até cada qual da primeira e segunda porções de entrada, as paletas de entrada definindo passagens de entrada axialmente adjacentes; em que a configuração das paletas de entrada que estendem-se até a primeira porção de entrada difere da configuração das paletas de entrada que estendem-se até a segunda porção de entrada, em que as plaetas que estendem-se até a primeira porção de entrada são circunferencialmente deslocadas das paletas que estendem-se até a segunda porção de entrada.variable geometry turbine - is described as variable geometry comprising a turbine wheel mounted for rotation about a turbine geometry within a housing, the housing defined as an annular inlet surrounding the turbine wheel and defined between first and second side walls input; and an axially movable cylindrical liner through the annular inlet to vary the size of the gas flow path through the inlet; wherein the annular inlet is divided into a first annular inlet portion and a second axially displaced annular inlet portion of the first inlet portion, inlet palettes extending axially to each of the first and second inlet portions, the pallets input defining axially adjacent input passages; wherein the configuration of the input palettes extending to the first input portion differs from the configuration of the input palettes extending to the second input portion, wherein the platelets extending to the first input portion are circumferentially offset from the palettes extending to the second inlet portion.
