Abstract

"FREIO HIDRODINâMICO". A presente invenção refere-se a um freio hidrodinâmico compreendendo um estator (1), um rotor (2), cujos rotor (2) e estator (1) são dispostos de modo que formam um espaço toroidal (7), um meio que é pretendido ser fornecido ao espaço toroidal (7) a fim de efetuar uma ação de frenagem, um primeiro circuito de tubo (35) que fornece transferência do meio de uma saída do espaço toroidal (7) para uma entrada para o espaço toroidal (7), e um segundo circuito de tubo (37) que fornece transferência do meio de um espaço de armazenamento (34) para o espaço toroidal (7) . O segundo circuito de tubo (37) fornece transferência do meio para o espaço toroidal (7) por meio de uma segunda entrada (44) que é separadamente disposta com relação à primeira entrada (42) para o primeiro circuito de tubo (35).
