Is there a swingable leno? -5 is inserted. Leno-5 is made by overlapping tension Leno-6 and control Leno-7, both Leno-6,
The lower end of 7 is pivotally connected to 70-tindareper 9 by a common pin 8 so as to be swingable. Ganosu 10 is placed on the upper side of Reno-7, and Panasu 10 is placed on Renno-7.
The flyweight 12 is housed in a casing 11 that is rotationally driven by an engine output shaft (power saving shown), and when the rotational speed of the casing 11 increases, the flyweight 12 moves toward the outside of the casing 11. oscillate. A governor sleeve 13 is supported within the casing 11 so as to be slidable in the axial direction along its center of rotation. -7 is projected toward the top. When the governor sleeve 13 is protruded, it comes into contact with the upper side of the control lever 7, and the control lever 7? -7 te/shi I

The upper part of the control spring 16 is connected to an adjusting lever 17 via a control spring 16, and the adjusting lever 17 is interlocked with an accelerator pedal (not shown) K. When the accelerator pedal is depressed, the tension of the control spring 16 becomes high, and a moment is given to the tensile system 6 that causes it to swing in the control 4-7 direction. The lever 5 swings to an angle at which the moment caused by the control spring 16 and the moment caused by the pressing force of the gaff 9/liner 13 are engaged.

安定した噴射量調整を行い得ることになる。The spill ring 3 is moved in the axial direction of the plunger 10 by the swinging of the lever 5 and, by extension, the swinging of the control lever 7, and the fuel injection amount is adjusted. Especially during rapid acceleration and deceleration when the tension of the control spring 16 changes rapidly,
The moment applied to the lever 5 also changes rapidly. Therefore, a damper 21 is connected to the upper end of the tension lever 6 to prevent the lever 5 from swinging rapidly due to sudden changes in moment. This allows for sufficiently stable injection amount adjustment during rapid acceleration and deceleration.
