Claims

[Claims for Utility Model Registration] A governor spring 5 is linked to a fuel metering device 2 of a fuel injection pump 1 of a diesel engine through a fork lever 3 and a floating lever 4 in order to bias it toward the fuel increase side r; A rotational speed detection actuator 6, which is activated by detecting the rotational speed of the engine, is linked to the fork lever 3 in a state where it is biased toward the fuel reduction side l, and the floating lever 4 is received by the fuel restrictor 7 at the full load position. The starting spring 8 is engaged with the fork lever 3 in a state that urges it toward the fuel increase side r, and a torque spring device 9 is provided between the fork lever 3 and the floating lever 4, and the torque spring device 9 is constructed by fitting a torque pin 9b into a spring case 9a so that it can move forward and backward, and biasing it toward the advancing side with a torque spring 9c, and attaching it to one of the fork levers 3 and the floating lever 4. In a torque spring device for a two-lever governor for a diesel engine, in which a spring case 9a is provided and the tip of a torque pin 9b is brought into contact with the other lever 4, a case support portion 10 is provided on one lever 3; A spring case 9a is fixed to the case support part 10 by screw fitting so that it can be adjusted forward and backward, and a contact part 1 for setting the amount of torque increase is brought into contact with the fork lever 3 and the floating lever 4.
1 and 12, and both contact portions 11 and 12 are arranged so as to contact each other before the other lever 4 comes into contact with the spring case 9a while the torque spring 9c is being compressed. Torque spring device for a two-lever governor for diesel engines.
