Abstract

A centrifugal force speed governor for fuel injected internal combustion engines having at least a negative adjustment capability. In such a centrifugal force speed governor the following structural components are included: speed responsive structure; at least one adaptation spring; an adjustment member; an intermediate lever; a yield support; a control element; a stop; an energy storing structure; and a setting lever having a pin mounted thereto. The adjustment member is coupled to the speed responsive structure, the adaptation spring, the control element and through the control element to the yield support, while the setting lever engages, with its pin, the intermediate lever, the control element and the energy storing structure. When the adjustment member is displaced by the speed responsive structure and under the regulation of the adaptation spring, a displacement of the intermediate lever via the control element and the setting lever pin occurs. This displacement of the intermediate lever is transferred to a fuel supply rate adjustment member of a fuel injection pump to which the intermediate lever is coupled, producing a negative adjustment of the fuel supply rate adjustment…
