Abstract
"ROTOR DE MáQUINA HIDRáULICA". A presente invenção refere-se a pás de rotor (1, 1<39>) de um rotor de máquina hidráulica que são formadas de tal maneira que, por um lado, uma alta eficiência possa ser alcançada, e que, por outro lado, a máquina hidráulica possa ser operada sem maiores restrições, mesmo em faixas de carga parcial, um bom comportamento de cavitação da máquina hidráulica sendo também desejável, e este rotor tendo também ainda que ser produzido tão simplesmente quanto possível, sem restrições devido às larguras livres muito pequenas, por meio de ferramentas de máquina. A fim de se atingir estes objetivos, de acordo com a invenção, é proposto um rotor no qual a borda de entrada (4, 4<39>) e/ou a borda de saída (5, 5<39>) de duas pás adjacentes do rotor (1, 1<39>) apresentam perfis variados em diferentes seções.
