Abstract
"DISPOSITIVO ROTATIVO POR PRESSãO DE FLUìDO". Um motor gerator (11) do tipo tendo uma válvula carretel (45), disposta em posição oposta ao eixo de acionamento principal (35). O motor também inclui um conjunto de discos de freio (104) acoplados a uma extensão (45e) da válvula carretel (45), e um conjunto de discos de freio (106) engrenados com endentamentos internos (108) definidos por uma tampa de extremidade (41). Um pistão (109) operável para engrenar os discos de freio (104, 106) está disposto em uma câmara definida pela seção de alojamento da válvula (19), disposta adjacente à tampa de extremidade (41). Um eixo de acionamento de válvula (57) tendo endentamentos (53) engrenando ao eixo de acionamento principal (35) em sua extremidade rotativa (33), também têm endentamentos (55) engrenando a válvula de carretel (45) para transmitir rotação pura do eixo de acionamento (35) para a válvula carretel (45). O resultado é um arranjo de acionamento de válvula e de freio muito compactos.
