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.

Abstract: A fuel injection pump with roller shaft for internal combustion engines, in which the roller is loosely journalled in a substantially cylindrical opening provided in a shaft or push member actuated in upward direction by a cam and in downward direction into its lower dead center position by a spring. The roller shaft or push member is at that end portion which is adjacent the roller provided with supporting surfaces by means of which the roller shaft when occupying its lower dead center position rests upon shoulders of a camshaft at opposite sides of the above mentioned cam. The diameter of the camshaft substantially equals the diameter of the high level portion of the cam. When the roller shaft rests on these shoulders, a gap is formed between the wall of the opening in the roller shaft and the roller so that sufficient lubricant can collect in the gap to assure proper lubrication of the roller, even when the roller shaft is under great load.
