PURPOSE:To surely fully close sub-throttle valves, by rotatably fitting a cylindrical body to a rotary shaft of the sub-throttle valve, pivotally mounting the cylindrical body to a common lever, further winding a coil spring around the cylindrical body and connecting the cylindrical body to the rotary shaft. CONSTITUTION:To open and close each sub-throttle valve 23, if a lever 27 is pulled, a disc 42 is rotated, further a cylindrical body 41 is rotated, and rotary motion is transmitted to a rotary shaft 25 through a disc 45, stopped to a spring 43, then the valve is closed. Then even if another sub-throttle valve initially reaches a full closing position, continuous further movement of the lever 27 causes only the disc 42 and cylindrical dody 41 to slidably rotate by an angle theta against the spring 43, and the cylindrical body 41 of each sub-throttle valve slidably rotates for the rotary shaft 25 till the last sub-throttle valve is fully closed, then position shifting of full closing can be absorbed. |
