Distributor type fuel injection pump for internal combustion engine has plunger piston with expansion section with part for absorbing rotational vibrations transferred to piston by drive shaft

摘要

The pump has a drive shaft driven by the engine, a lateral cam connected to the drive shaft via a coupling and a pump element with a pump plunger piston (9) with a section (53) arranged in a pump cylinder and an expansion section (54) extending towards the cam. The expansion section has a section (61) for absorbing rotational vibrations transferred to the piston by the drive shaft.
