ABSTRACT:
A distributor type fuel injection pump which is provided with an eccentric connecting member coupling the timer piston of the injection timing control device to the roller holder. The eccentric connecting member comprises a first portion and a second portion eccentrically combined together. The first portion engages with the roller holder to support a predetermined one of the rollers on the roller holder, which is rotatably fitted thereon, whereas the second portion pivotably engages with the timer piston. Further provided is means for prohibiting pivotal movement of the second portion of the eccentric connecting member about the first portion of same relative to the roller holder. Displacement of the timer piston causes accurately corresponding circumferential displacement of the roller holder through the eccentric connecting member and the pivotal movement-prohibiting means to thereby achieve accurate control of the injection timing in response to the rotational speed of the engine.
