Injection pump for internal combustion engine, particularly for internal combustion engine operated with diesel oil, comprises eccentric shaft with eccentric tappet, rotating ring mounted on eccentric tappet and piston supported on ring

摘要

The injection pump comprises an eccentric shaft (3) with an eccentric tappet (4), a rotating ring (5) mounted on the eccentric tappet and a piston (6) supported on the ring. The eccentric shaft is supported in the housing (1) and rotates around an axis. The ring is limited on the overall outer periphery by a continuously proceeding path (8). The piston and a guiding pin (9) are supported opposite to the path. The piston and the guiding pin are connected by a rigid clamp (10). The clamp surrounds the ring at a distance.
