摘要
A fuel injection pump for an internal combustion engine includes at least one pump piston movably disposed in a piston sleeve which piston sleeve is fitted in a pump housing. A first arrangement associated with the piston draws fuel through suction ports into a working chamber of the pump during a piston suction stroke. A second arrangement associated with the piston cuts off a connection to a suction side of the pump and thereafter initiates a delivery from the working chamber to an injection nozzle, which delivery is divided into two phases. The second arrangement is operable during a piston delivery stroke. A third arrangement controls the phases and includes the suction ports and an inside edge of the piston sleeve. The inside edge of the piston sleeve is provided on a planar end face of a guide bore of the sleeve and faces the working chamber.
