Abstract

ESTRUTURA DE MONTAGEM PARA MECANISMO DE BICO INJETOR VARIáVEL EM TURBOCOMPRESSOR DE EXAUSTãO DE ABERTURA VARIáVEL. é fornecido um turbocompressor de exaustão de abertura variável em que uma montagem de bico injetor incluindo um engaste de bico injetor e palhetas de bico injetor tem uma estrutura de suporte firme sem distúrbio provocado por uma deformação térmica de uma carcaça de turbina e por uma força externa exercida na carcaça de turbina, e uma parte de caracol é formada em uma configuração substancialmente aberta de maneira que a montagem de bico injetor pode ser formada de modo simples a fim de reduzir a quantidade de núcleos de molde para um caracol durante a fundição da carcaça de turbina, e assim é possível aprimorar a produtividade da carcaça de turbina.ASSEMBLY STRUCTURE FOR VARIABLE INJECTOR NOZZLE MECHANISM IN VARIABLE OPENING EXHAUST TURBO. A variable aperture exhaust turbocharger is provided wherein a nozzle assembly including a nozzle bezel and nozzle vanes has a firm undisturbed support structure caused by thermal deformation of a turbine housing and an external force exerted on the turbine casing, and a snail portion is formed in a substantially open configuration such that the nozzle assembly can be formed simply to reduce the amount of mold cores for a snail during casting of the casing. turbine casing, and thus it is possible to improve the productivity of the turbine casing.
