Abstract

"ORGãO, RODA DE MáQUINA HIDRáULICA, MáQUINA HIDRáULICA, E, PROCESSO DE MONTAGEM DE UMA RODA". Este órgão (10) é provido com uma superfície axialmente simétrica (11a) apta a ser disposta no prolongamento da superfície molhada (31a) da porção superior (3) ou do cubo de uma roda de máquina hidráulica e convergente, ao se afastar desta superfície molhada (31) e em direção do eixo de rotação (X-X<39>) da roda (1) quando o órgão é fixado sobre a roda (1). Este órgão (10) é igualmente provido de uma segunda superfície axialmente simétrica (13a) deslocada axialmente em relação à primeira superfície convergente (11a), esta segunda superfície (13a) sendo divergente ao se afastar da primeira superfície convergente (11a).
