Abstract
TURBINA DE GEOMETRIA VARIáVEL A turbina de geometria variável, especialmente uma turbina de gás, compreendendo uma carcaça (2, 22), um rotor da turbina (4), um espiral de entrada de fluido (1) que circundo o referido rotor da turbina, um bocal em formato de aleta interposto entre o referido espiral de entrada e o referido rotor da turbina concebido para acelerar o fluxo de fluido, o referido bocal compreendendo um anel axialmente ajustável (5, 25) concebido para variar a abertura de bocal (3, 23) e tendo uma parede (19) delimitando a referida abertura de bocal, a referida parede tendo furos de contrapeso (6, 26, 26<39>) conectando a abertura de bocal com uma câmara (12) limitada pela referida carcaça e pelo referido anel, caracterizada pelo fato de que as bordas (16), formadas pelos referidos furos com a superfície (18) da referida parede faceiam a referida abertura de bocal, são arredondadas generosamente na porção (17, 17<39> localizada a montante do furo com relação ao fluxo de fluido. Turbocharger e motor sobrealimentado que compreendem a referida turbina.
