Abstract
MÉTODO PARA EQUILIBRAR TRAÇÃO EM UMA TURBINA DOTADA DE UM ROTOR GIRATÓRIO, TURBINA E MOTOR DE TURBINA. A presente invençãorefere-se em geral a métodos par a equilibrar a tração, assim como a turbinas e a motores de turbinas que implantam esses métodos. Método para equilibrar tração em uma turbina (3) dotada de um rotor giratório, que compreende as etapas de: proporcionar uma primeira fonte de pressão fora da dita turbina (3), proporcionar uma câmara de pressão (30) dentro da dita turbina (3), em que uma parede (33) da dita câmara de pressão (30) atua no dito rotor, de modo a equilibrar a tração exercida pelo dito rotor, quando o mesmo gira; conectar a dita primeira fonte de pressão à dita câmara de pressão (30) por meio de um primeiro conduto; associar uma primeira válvula ao dito primeiro conduto (C1), sendo que a dita primeira válvula (V1) é disposta para abrir e fechar o dito primeiro conduto (C1); em que a dita primeira válvula (V1) é disposta para abrir automaticamente, quando a pressão a montante da dita primeira válvula (V1) exceder um primeiro valor de limiar predeterminado.
