Excess fuel starting device for diesel engines

Claim 1

In a diesel engine fuel injection pump governor having a governor shaft driven at a speed proportional to engine speed, a non-rotating sleeve slidably disposed on said shaft, a flyweight assembly mounted on said shaft for rotation therewith and having at least one flyweight rotatably mounted to swing radially outwardly in response to centrifugal forces during rotation of said shaft, said flyweight in the rest position being disposed in contiguous relation to said sleeve, means on said flyweight for moving said sleeve along said shaft in response to radial movement of said flyweight, spring means acting on said sleeve opposing sleeve movement by said flyweight, a fulcrum lever pivotally connected at a point remote from its ends to said sleeve, an engine fuel control rod, a first end of said fulcrum lever being connected to said engine fuel control rod, a full load stop plate adjacent said first fulcrum lever end, means on said fulcrum lever end for engaging said stop plate to limit the travel of said fulcrum lever end and control the full load fuel delivery position of said fuel control rod, a trunnion lever pivotally connected to the second end of said fulcrum lever, an operating lever shaft rotatably disposed adjacent said fulcrum lever, said trunnion lever being rotatably mounted on said operating lever shaft, spring means connecting said trunnion lever with said operating lever shaft to resiliently rotate said trunnion lever with said operating lever shaft in at least one direction, and an operating lever connected to said operating lever shaft, the improvement comprising spring means associated with said stop plate permitting movement of said stop plate to an excess fuel position under a predetermined force of said fulcrum lever thereagainst, means on said flyweight for locking said flyweight to said sleeve during cranking of the engine to prevent radial flyweight movement and axial sleeve movement, and means connecting said operating lever shaft directly with said fulcrum lever second end during engine cranking at full throttle setting to provide said predetermined force of said fulcrum lever against said full load stop, thereby establishing an excess fuel position of said stop and of said fuel control rod.
