Abstract
Abstract An internal combustion engine crankshaft governor disposed between the banks of angularly related sections of a fuel pump and comprising a crosspiece with centrifugal flyweights rotated by the crankshaft of the engine. The fly-weights act on a coupling and therethrough on a double-arm lever connected with one of the pump rack bars controlling fuel supply and balanced by a spring. The double-arm lever is rotatably mounted on a pivot spindle secured in the pump housing and positioned normally to the plane passing through the longitudinal axes of the rack bars. The tension of the spring is controlled by the angle through which a control lever turns. The control lever is rotatably mounted on another pivot spindle secured in the pump housing and positioned normally to the plane passing through the longitudinal axes of the rack bars.

An internal combustion engine crankshaft governor disposed in the space between the banks of angularly related sections of a fuel pump incorporating two rack bars controlling fuel supply, comprising: a crosspiece rotated by said crankshaft of the internal combustion engine; centrifugal flyweights; pivot spindles for mounting said flyweights on said crosspiece; a coupling for converting the rotary movement of said centrifugal flyweights to the translatory movement of said two rack bars of said fuel pump controlling fuel supply; a double-arm lever actuated by said centrifugal flyweights through said coupling and having one arm connected with one of said rack bars of said fuel pump; a pivot spindle secured in the housing of said pump and positioned normally to the plane passing through the longitudinal axes of said rack bars, said pivot spindle carrying said lever rotatably mounted thereon; a spring for balancing the effort of said lever having one end connected with the other arm of said lever; a control lever for adjusting the tension of said spring connected with the other end of said spring; one more pivot spindle secured in the housing of said pump, positioned normally to the plane passing through the longitudinal axes of said rack bars and carrying said control lever rotatably mounted thereon.
