Distributor-type fuel injection pump for internal combustion engines, especially those used as direct injectors for commercial vehicles

摘要

The invention relates to a distributor-type fuel injection pump intended for internal combustion engines with direct fuel injection, with a distributor piston which performs rotational and reciprocating movements, has a longitudinal bore, a shutoff bore and a distributor groove and, for interrupting the fuel feed during a working cycle of an internal combustion engine cylinder, has a control bore branching off from the longitudinal bore and a spill recess situated in its outer surface, which in the course of the effective stroke can be connected by a flow chamber recessed in the distributor head of the distributor-type fuel injection pump.
