ABSTRACT:
A coupling device for use in diesel fuel injector pumps having a plurality of rotary pumps connected to a drive shaft and positioned in a housing along a longitudinal axis and having a generally cylindrical weight retention housing for rotatably supporting a plurality of flyweights which are coupled to a fuel control system. The coupling device employs an annular drive ring adjacent to the weight housing for engaging the drive shaft and a plurality of drive pins connected to the weight housing and projecting through elongated apertures in the drive ring. A plurality of resilient inserts are positioned within the elongated apertures immediately adjacent to the drive pins so as to occupy substantially all aperture volume not occupied by the pins. An annular capture ring dimensioned to reside in a depression on a a back surface of the drive ring is connected to the drive pins, which do not extend beyond the back surface of the drive ring, and captures the resilient inserts between the weight housing and the capture ring.
