Claims (1)

[Scope of Claim for Utility Model Registration] The governor lever 1 of the governor G of the diesel engine E is connected to the speed regulating lever 3 via the governor spring 2.
In the speed governor of a diesel engine, the fulcrum 4 of the speed governor lever 3 is located on the opposite side of the fulcrum 5 of the governor lever 1 with the governor spring 2 inside, and the governor spring 2 pulls the governor lever 1. Set the tightening pull angle θ to an acute angle, and adjust the speed regulating lever 3.
The pull angle θ is configured such that the value of the pull angle θ increases as the speed controller approaches from the low-speed operating position B to the high-speed operating position C, and when the governor lever 1 is in the no-load position A, the fulcrum 4 of the governor lever 3 is aligned with the governor lever 1. The separation distance away from the driven side engagement point 6 with the governor spring 2 is set close to the arm length r from the fulcrum 4 of the speed regulating lever 3 to the driving side engagement point 7 between the governor spring 2 and the speed regulating lever 3. , perpendicular to the imaginary straight line P connecting the driven side engagement point 6 and the regulating lever fulcrum 4, and at the regulating lever fulcrum 4.
Assuming an imaginary reference line S passing through the imaginary reference line S, position the regulating swing region T between the low-speed operating position B and the high-speed operating position C of the regulating lever 3 across this imaginary reference line S, and The speed lever 3 is composed of a proximal arm 10 and a distal arm 12, the proximal arm 10 is rotatably supported on the fulcrum 4, a governor spring 2 is attached to the distal arm 12, and the proximal arm 10 is rotatably supported on the fulcrum 4. side arm 10
By fixing the distal arm 12 so that the angle can be adjusted via the angle adjusting operation member 14, and adjusting the angle α between the distal arm 12 and the proximal arm 10 using the angle adjusting operation member 14, the above-mentioned A mechanical speed governor for a diesel engine, characterized in that an arm length r is configured to be adjustable.
