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 primeira válvula de registro (17), uma segunda válvula de registro (23) e um dispositivo de desativação seletiva (35). as válvulas de registro são dispostas em série em uma passagem de fluido entre a primeira câmara (13) e a segunda câmara (15). o dispositivo de desativação seletiva (35) é implantável e é configurado para desativar seletivamente a primeira válvula de registro (17) ou a segunda válvula de registro (23) mediante implantação. através da temporização da implantação do dispositivo de desativação, a direção de fluxo entre a primeira (13) e a segunda câmaras (15) 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.
