<p>The governor includes a force transmission lever subject to the prestressing force of a main governor spring, which lever the governor sleeve comes into operative contact after traversing an idling sleeve path a, and a leaf spring acting as the idling spring. The leaf spring is supported between its two ends on a curved rolloff path, determining its effective spring length, of a support bearing, the operative position of which is adjustable toward the leaf spring in accordance with the pivot angle ( beta ) of an adjusting member by means of an adjusting cam actuable by the adjusting member such as to increase the prestressing force of the leaf spring. The adjusting cam is supported on the force transmission lever in order to prevent influencing the maximum engine speed. With the adjusting member shifted from the idling position toward the full-load position, the corresponding governor characteristic curve is shifted, simultaneously with an increased supply quantity controlled by the governor, toward a higher partial-load engine speed, and by means of the spring rate of the leaf spring which changes as the engine runs up to maximum speed, governor characteristic curves are produced which continuously drop exponentially.</p> |
