Patent ID: 6901909

Claim:
A centrifugal governor for being incorporated in the horizontal diesel engines, comprising: a cylinder block including a cylinder transversely arranged and a crankshaft arranged perpendicular thereto; a gear case provided in front of the cylinder block; a fuel pump housed in the gear case toward the cylinder, the fuel pump including a fuel adjuster; a governor weight located toward the crankshaft; a governor lever provided between the governor weight and the fuel pump, wherein the governor lever is pivoted to a pivot in such a manner as to rotate in a horizontal plane; a spring supporter extending from a middle part of the governor lever; a speed-adjusting lever provided nearer the fuel pump than the spring supporter, in such a manner as to enable the lever to rotate in a horizontal plane; a main spring fixed to the speed-adjusting lever at one end and to the spring supporter at the other end; and an idling spring fixed to the governor lever at one end, and to the front wall of the gear case at the other end; wherein the governor lever, when operated, applies a synthesized tensile force (STF) of the tensile forces (GS) of the main spring 4 and the tensile force (IS) of the idling spring to the fuel adjuster of the fuel pump so as to increase the supply of fuel, and cause the governor weight to decrease the fuel amount by pushing down the fuel adjuster, so that a disequilibrium between the synthetic tensile force (STF) of the two springs and the governor force (GF) is utilized for increasing or decreasing the supply of fuel through the operation of the fuel adjuster; wherein the idling spring is constituted as a tension coiled spring; wherein the idling spring spring-biases the governor lever in the direction of increasing supply of the fuel both in the non-load set and in the low-load set (LL), and negates the spring-biasing both in the high-load set (LH) and in the full-load set.
