Electromechanical run/stop actuator for diesel engine
First Claim
1. An electromechanical run/stop actuator for a diesel engine fuel pump governor of the kind comprising a plurality of housing members conjointly affording a housing for the governor, a plurality of housing fasteners for securing the governor housing members to each other, and a run/stop member rotatable through a predetermined angle between alternate STOP and RUN positions, the actuator comprising:
- a bracket having a base with a configuration complementary to a portion of the governor housing spaced from the run/stop member;
main bracket fastener means, including at least one fastener for replacing at least one housing fastener, for mounting the bracket on the governor housing;
a support rod having one end affixed to the bracket at a location displaced from the main bracket fastener means;
support rod fastener means, including a fastener for replacing at least one housing fastener for affixing the other end of the support rod to the housing at a location displaced from the bracket, thereby bracing the bracket to withstand vibration of the engine;
a solenoid, affixed to the bracket, having a plunger aligned with the run/stop member and movable between alternate extended and retracted positions in response to changes in energization of the solenoid, the solenoid including a spring biasing the plunger toward one of its alternate positions;
a lever mounted on the run/stop member;
a connecting rod of predetermined length having one end affixed to the lever;
and a swivel connection between the other end of the connecting rod and the plunger,whereby energization of the solenoid drives the lever to rotate the run/stop member to one of its alternate positions and de-energization of the solenoid permits the spring to drive the lever to rotate the run/stop member to its other alternate position.

Abstract
A solenoid is affixed to a bracket having a base complementary in configuration to a portion of the housing of a diesel engine fuel pump governor that is spaced from the governor'"'"'s run/stop member; the bracket is mounted on the governor housing by two bolts that also serve to join two halves of the governor housing. A lever mounted on the run/stop member of the governor is connected, by a connecting rod and swivel connection, to the solenoid plunger, so that plunger movement responsive to energization of the solenoid rotates the run/stop member to a RUN position; on de-energization of the solenoid its spring drives the run/stop member to a STOP position. A support rod affixed to the center of the bracket and mounted to the governor housing by a cover mounting bolt braces the bracket against engine vibration.
