9 Regulating Linkage
9.1 Length of Lever Arm
The length of the lever arm is determined in such a way that approx. 90 % of the governor
output shaft adjustment angle can be used. Based on this, the rack length L of governors
with 36° adjustment angle is calculated as L = 1.8 a, "a" being the travel distance of the
injection pump or the carburettor.
9.2 Order Specification for Lever Arm
Please order RH 16 - 01 (EDV- No.: 504 170 02 00)
9.3 Connecting Linkage
The connecting linkage from the governor to the injection pump or the carburettor should
be length-adjustable and have a (pressure or tension) elastic link. If possible, joint rod
heads in accordance with DIN 648 should be used as connecting links. The linkage must
operate easily and without clearance.
In case of friction or backlash in the linkage connecting actuator and injection pump resp.
throttle valve no optimal control is possible.
