摘要

The drive for a pump/jet fuel injection valve, at an internal combustion motor, has an axis (10) with a rocker arm (12) for each pump/jet. Each rocker arm is flanked by two locking rings (20), fitted in radial peripheral grooves (26), to prevent an axial sliding movement. The axial ends (14,16) of each rocker arm lie directly at the locking rings, with a projection (22) over each ring in the axial direction (18).
