Resilient diesel governor coupling

A coupling device for use in diesel fuel injector pumps, as used in diesel engine fuel flow regulation and timing, where the pumps have a main housing for confining a plurality of rotary pumps positioned in series along a longitudinal axis and being connected through a drive shaft to a driving source, and having a generally cylindrical weight retention housing positioned adjacent to the rotary pumps with a central opening for passage of the drive shaft therethrough and a series of recesses about its circumference for rotatably supporting a plurality of flyweights which are coupled to a fuel control system, comprising:

• an annular drive ring having a central aperture for passage of said drive shaft with at least one key extending therefrom for engaging said shaft, being positioned on said shaft adjacent said governor weight housing with one of two opposing planar surfaces facing said weight retention housing, having a plurality of elongated apertures extending between the opposing surfaces at predetermined radial and angular positions about the ring and an annular depression centrally located between an outer edge and an inner edge on a back surface facing away from said weight retention housing;
• a plurality of drive pins, corresponding in number to said elongated apertures being secured on a first end to said weight retention housing and extending through said drive ring elongated apertures, with a second end of said drive pins not extending beyond said back surface, the drive pins having a diameter smaller than a width of the apertures to allow freedom of motion therein;
• a plurality of resilient inserts positioned within said elongated apertures immediately adjacent said drive pins so as to occupy substantially all volume not occupied by said pins;
• and
• an annular capture ring having an outer and inner diameter corresponding to dimensions for said annular depression in said drive ring, being connected in several locations to said second ends of said drive pins so as to capture said inserts within said elongated apertures.
