Mechanical Hydraulic Actuator

  •  the conventional linear actuator powered by a dual hydraulic power supply system (viz. blue channel and green channel).
  •  In this type of actuator, the mechanical signal and the electrical signal can act on the summing link of the actuator.
  •  in which the servo valve (SV) converts the electrical command to the movement of the ram with the high-pressure hydraulic fluid supply.
  •  As the ram moves, the feedback the link will rotate the summing link about the upper pivot, returning the servo valve input to the null position as the command position is achieved.
  • The performance of the hydraulic actuator is to satisfy the demand with the hydraulic power-assisted mechanical response.
