摘要

The injection pump has a piston (1), which is adjustable in a cylinder (2) by eccentric cam (5) of an eccentric shaft (6) rotating in housing (3) around an axle (4). A ball race (7) forms the piston with a ring-shaped track in a locking manner, where ring-shaped track is continuously running at an end turned at the eccentric cam.
