Abstract

trata-se de um atuador eletromagnético giratório (2) que inclui uma montagem de inclinação (30) para aplicar um torque a seu rotor (4). tal atuador pode ser usado para operar uma válvula tubular de um motor de combustão interna. o rotor define uma superfície de came (14), e a montagem de inclinação inclui um seguidor de came (16) em engate com a superfície de came, e a grandeza do torque exercida no rotor pela montagem de inclinação é dependente da grandeza do deslocamento do seguidor de came pela superfície de came. a superfície de came define pelo menos um detentor (50) para receber o seguidor de came.
