Rpm Governor for fuel-injected interval combustion engines, especially a centrifugal governor of an injection pump for diesel motor vehicle engines

An rpm governor for a fuel-injected internal combustion engine, in particular, a centrifugal rpm governor of an injection pump for a Diesel motor vehicle engine, having a housing, a governor member which adjusts in accordance with rpm, a supply quantity adjustment member, at least one intermediate lever wherein control movements of said governor member are transmissible via said at least one intermediate lever onto said supply quantity adjustment member of said injection pump, and an idling spring wherein said governor member operates within an idling sleeve path of travel against the force of said idling spring, said rpm governor having an idling correction apparatus including an electromagnet having a coil, an armature and a pressure pin which is firmly connected to said armature and in pressure contact with said idling spring which influences the idling operation and said electromagnet is triggered in accordance with at least one engine parameter by means of a control circuit characterized in that said governor member can be acted upon additionally by an adjustment force of said electromagnet, which said adjustment force is variable by means of an energizing current of said control circuit in accordance with at least said one engine parameter and is independent of an adjustment path within which said electromagnet operates in order to maintain the idling rpm.
