Abstract
TURBOCOMPRESSOR DE GASES DE ESCAPE COM GEOMETRIA DE TURBINA AJUSTÁVEL. A invenção refere-se a um turbocompressor de gases de escape (1) para um motor de combustão interna (2) que tem um conduto de admissão (3) de ar e tendo um conduto de gases de escape (5) e que tem uma turbina (6) disposta no conduto de admissão e tendo um rotor do compressor (4) disposto no conduto de admissão, cuja turbina e rotor do compressor estão ambos dispostos sobre um eixo comum (24), em que o conduto de admissão tem um invólucro em espiral (7) que envolve coaxialmente a turbina (6), e em que, entre o invólucro em espiral e a turbina, é proporcionada uma fenda em forma de anel (8) através da qual o fluxo de gases de escape flui circunferencialmente para a turbina e em que, na fenda em forma de anel, estão dispostas as palhetas de guia (9, 9', 9'', 9''', 10, 11) que podem ser rotativas em torno de um eixo de ajuste (12) por meio de um mecanismo de ajuste (12, 17) com o objetivo de controlar a resistência do fluxo. Para poder compensar expansões térmicas e encolhimentos das palhetas de guia em diferentes condições operacionais, é fornecido de acordo com a invenção que o mecanismo de ajuste das palhetas de guia (9, 9 ', 9' ', 9' '', 10, 11), ainda, tem um mecanismo de deslocamento (18, 18a, 18b, 20, 21, 22) para o deslocamento das palhetas de guia (9, 9', 9'', 9''', 10, 11) na fenda em forma de anel (8). O mecanismo de deslocamento pode ser acoplado diretamente ao mecanismo de ajuste.
