Injection pump for internal combustion engine, has suction chamber and high-pressure chamber connected over spill port arrangement by controlling edge, where two spill ports are guided directly into suction chamber as suction pipes

摘要

The injection pump has a suction chamber (4), a high-pressure chamber (2) and an intake port arrangement. The intake port arrangement has two intake ports (3.1,3.2) for fuel supply, where the intake ports connect the suction chamber and the high-pressure chamber. The suction chamber and the high-pressure chamber are connected over a spill port arrangement by a controlling edge (5), where two spill ports (6.1,6.2) are guided directly into the suction chamber as suction pipes.
