Claims

[Claims for Utility Model Registration] 1. A plunger 3 is fitted into a plunger barrel 2 of a fuel injection pump 1 of a diesel engine via a tappet 4 so that it can be driven vertically by a fuel injection camshaft 20, and the plunger 3 is fitted into a control sleeve 5.
In a fuel injection amount adjustment device for a diesel engine, in which a control rack 7 is interlocked with the plunger barrel 2 so as to be able to rotate relative to the plunger barrel 2 via a rack receiving portion 6, a power transmission portion 8 in which the control rack 7 and the rack receiving portion 6 engage with each other. The part on the control rack side facing the power transmission part 8 is defined as a rack-side transmission section 10, and the side of the rack receiving section 6 and control sleeve 5 facing the power transmission section 8 is defined as a sleeve-side transmitted section 12, and the rack-side transmission section 10 and the sleeve side Transmitted part 12
The output part 15 of the idle rotation absorption spring 14 is interlocked with the output part 15 of the idle rotation absorption spring 14 to be able to transmit the spring force, and the fixing part 16 of the idle rotation absorption spring 14 is fixed to the other side. A fuel injection amount adjusting device for a diesel engine, characterized in that a rack receiving portion 6 is biased to rotate relative to a control rack 7. 2. A plunger 3 is fitted into the plunger barrel 2 of a fuel injection pump 1 of a diesel engine via a tappet 4 so that it can be driven up and down by a fuel injection camshaft 20, and the plunger 3 is fitted into a control sleeve 5.
In a diesel engine fuel injection amount adjustment device in which a control rack 7 is connected to a plunger barrel 2 so as to be able to rotate relative to the plunger barrel 2 via a rack receiving part 6, the tappet 4 is positioned in a non-rotatable manner on the plunger barrel 2, and the plunger 3 is The output part 15 of the idle rotation absorption spring 14 is connected to either one of the and tappet 4 so as to transmit spring force, and the idle rotation absorption spring 14 is connected to the other side.
The fixing portion 16 of the plunger 3 is fixed, and the plunger 3 is moved through the tappet 4 to the control sleeve 5 by the spring force of the rotation absorption spring 14.
1. A fuel injection amount adjustment device for a diesel engine, characterized in that the device is configured to be biased to rotate relative to the fuel injection amount.
