Centrifugal rpm governor for fuel injected internal combustion engines, especially an idling and final rpm governor for diesel vehicle engines

A centrifugal rpm governor for fuel injected internal combustion engines including a housing, comprising an intermediate lever which is coupled with the supply quantity adjustment member of the injection pump which is engaged by both a control member moved by means of flyweights in accordance with rpm and a setting member which is pivotable for the purpose of arbitrary variation of the supply quantity, said governor further including a force transmitting lever which contacts a fixed stop attached to the housing, under the prestressing force of a main control spring, with which said force transmitting lever the control member comes into effective contact after covering an idling sleeve path against the force of an idling spring, further wherein said force transmitting lever is provided with an additional idling spring, further wherein the force of said additional idling spring is made partially ineffective by a thrust member that cooperates with said setting member when said setting member is pivoted by means of a service lever about a pivotal axis to advance to a full-load position, said thrust member comprising an adjustable thrust screw that is positioned securely on said setting member at a radial distance (c) from said axis of said service lever.
