PLUG-IN PUMP FOR A COMMON-RAIL SYSTEM AND ENGINE ARRANGEMENT HAVING AN INTERNAL COMBUSTION ENGINE HAVING A COMMON RAIL SYSTEM AND HAVING A PLUG-IN PUMP

摘要

The plug-in pump 2 for the common rail system has a pump housing 7, a fuel inlet 33, and a fuel outlet 36 with a cylinder formed therein and a piston 24 introduced in the cylinder. The pump housing 7 further has a plug-in section 8 for inserting the pump housing 7 into the opening 10 of the engine component 6 and has a plug-in section 8 for fixing the pump housing 7 to the engine component 6 Has a flange (12) that defines the boundary of the plug-in section (8). To cool the plug-in pump, the pump housing 7 has at least one flow tube 38 with a separate fluid inlet 48 and a separate fluid outlet 52. The fluid inlet 48 is connectable to the fluid discharge line of the internal combustion engine and the fluid outlet 52 is connectable to the fluid receiving line of the internal combustion engine.
