Abstract
A control valve control apparatus includes a pivotally mounted accelerator lever linked to an accelerator operation and having a first engagement member, a drive lever linked to an actuator and having a second engagement member, a pivotally mounted control valve shaft lever assembled integral with a control valve and having a third engagement member, and a link lever for linking together the beforementioned levers. When the actuator 41 is not operated, the link lever 51 turns the control valve shaft 3 by means of the third engagement member 7 and the first engagement member 27 linked to accelerator operation. When the accelerator operation is fixed with the actuator operated, the link lever turns the control valve shaft 3 by means of the third engagement member 7 and the second engagement member 47 linked to the actuator 41. This arrangement provides a control valve control apparatus having few components and low cost.
