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. |
