ABSTRACT:
A mechanical speed regulator for an injection pump which has centrifugal weights on its drive shaft. The centrifugal weights shift the regulator or control pin axially against the force of a starting supplementary feed spring, whereby in operation the control pin additionally is balanced or equalized with a control spring. The control spring is arranged at one end and the control pin is arranged at another end of a beam arranged to swing freely. A suspension of the beam is shiftable in the longitudinal direction of the beam. The suspension of the beam is arranged and embodied practically free of friction, for instance point journalling being provided therewith. The control pin at its free end provides a knife edge which fits into a correspondingly embodied depression or recess in the beam, and the beam has a conical tip elevation for receiving the control spring. An adjustable abutment is provided in the form of a set screw on the beam in the axial extension of the control spring. The preloading of the control spring is adjustable in a freely selectable manner by a speed adjustment lever arranged externally on the regulator housing.
