Abstract
Governors for diesel engines use a torque-spring to control the slope torque-rise curve as the rack actuator moves between the balance point and full load position. At present, it is difficult to adjust the torque spring mechanism to obtain the correct amount of rack movement between these positions. In the present invention, a first adjustment screw (33) is engageable with the torque spring (20), a second adjustment screw (34) is engageable with a fixed stop member (24), and a means (40) concurrently moves the first screw (33) in spring-deflecting engagement with the torque spring (20) and moves the second screw (34) towards engagement with the stop member (24) in response to fuel-increasing movement of the rack actuator (12), with further fuel-increasing movement of the rack actuator (12) being prevented by engagement of the second screw (34) with the stop member (24).
