Abstract

uma disposição de faseador de temporização de came variável (201) é revelada, compreendendo: um rotor (3) que tem pelo menos uma pá (5); um estator (7) que circunda coaxialmente o rotor (3), que tem pelo menos uma reentrância (9) para receber a pelo menos uma pá (5) do rotor, em que a pelo menos uma pá (5) divide a pelo menos uma reentrância em uma primeira câmara (13) e uma segunda câmara (15); e uma montagem de controle para regular o fluxo de fluido hidráulico a partir da primeira câmara (13) para a segunda câmara (15) ou vice-versa. a montagem de controle compreende uma válvula de controle de atuação de torque de came (17) que compreende um corpo de válvula (22) e um elemento de obturação hidráulico (hse) (25). o hse abre e fecha entre duas posições em resposta à sobrepressão na primeira ou na segunda câmara. cada uma dessas duas posições previne o fluxo entre as câmaras. implantar um dispositivo de bloqueio (37) impede que o hse (25) alcance uma dentre as duas posições, permitindo, assim, o fluxo unidirecional entre as duas câmaras (13, 15). temporizando-se a implantação do dispositivo de bloqueio (37), a direção de fluxo pode ser controlada. um método para controlar a temporização de eixo de came também é revelado, assim como um motor de combustão interna e um veículo que compreende a disposição de faseador de temporização de came variável revelada.
