Centrifugal RPM governor for fuel injected engines

摘要

A centrifugal rpm governor is proposed for fuel injected internal combustion engines in which the full-load supply quantity is precisely settable at a fixed and invariable full-load setting and a predetermined constant pivot angle of the setting member actuated by the service lever. The governor includes an intermediate lever that is coupled with the supply quantity adjustment member of the injection pump, which intermediate lever is engaged both by a control member that is moved by flyweights in accordance with rpm and a setting member pivotable for the purpose of arbitrarily varying the supply quantity. The setting member and the control member both are articulated on the intermediate lever via a shift lever connecting both members, and the intermediate lever is provided with a pivotal bearing adjustable in the governor housing solely for the purpose of accomplishing the basic setting of the full-load supply quantity. The pivotal bearing serves simultaneously as a deflection member in order to prevent an overload of the control rod during an undergoverning situation.
