Abstract

A speed governor for fuel injection pumps of internal combustion engines in which part of an oscillation damper member, in the form of a capsule, is disposed between a drive shaft and a flyweight adjuster; two claws of a support that receives the flyweights of the centrifugal adjuster and two claws of a coupling element connected to the drive shaft. The two claws are connected to one another by way of a segmented type buffer element, all of which protrude into the capsule. The claws of the coupling element protrude into the open part of the capsule, while the claws of the support protrude into the capsule through openings in the capsule bottom. For the sake of greater strength of the capsule, the openings are embodied in closed form according to the invention.
