ABSTRACT:
A mechanical governor for a Diesel construction vehicle engine includes a centrally pivoted torque lever 32 whose lower end is proximate a stop pin 33 on the lower end of a conventional main spring tension lever 9, and whose upper end is cammed against an adjustable torque spring 29 by an extension arm 19a integral with a conventional speed control lever 18 at low or partial load speed settings. This pivots the lower end of the torque lever 32 away from and out of engagement with the pin stop 33, whereby the torque spring 29 is inoperable and no additional engine slowdown is caused thereby. At full throttle or maximum load settings, however, the extension arm 19a releases the torque lever 32 and the torque spring 29 pivots the lower end of the arm into engagement with the pin stop 33. Thus, the added restraining force of the torque spring retards the speed increasing movement of the tension lever, to thereby provide the desired anti-stall delay during which the operator has time to back off or shift to a lower gear ratio.
