Abstract

Patente de Invenção: <B>"ROTOR DE UM TURBOGERADOR COM REFRIGERAçãO DIRETA A GáS"<D>. Numa máquina elétrica refrigerada a ar com refrigeração reversível em circuito fechado de refrigeração é previsto, entre uma placa de tampa de rotor (22) e uma árvore de rotor (28), uma grade de corrente de dois estágios para um abastecimento ótimo do rotor (4) e do enrolamento de rotor (29) com ar de refrigeração. O primeiro estágio da grade de corrente (30b) em direção da corrente é uma grade de retardo com características geradores de pressão. O estágio da grade de corrente (30a) que segue em direção da corrente é uma grade de retardo com caracteristica de mudança de direção.
