Zusammenfassung: | A fuel injection pump for internal combustion engines having a pump housing (11) which is protected against cavitation and erosion caused by the jet of fuel emerging with high energy from a spill port (24) at the termination of injection. The fuel injection pump (10) includes a baffle rod (26) which is made from a round rod and which is fitted in the pump housing (11) in a plane at right angles to the axis of the pump piston and at a distance from the said axis and which is located opposite to the spill port (24). The baffle rod (26) incorporates pocket-like depressions (29) which intercept the emerging jet of fuel and which are provided with a return-flow passage for the spilled fuel and each pocket- like depression being defined above and below the spill port (24) by a respective web (26a) which arcuately surrounds the pump cylinder (12). |
