Plug-in pump for a common rail system and engine arrangement with an internal combustion engine, a common rail system and a plug-in pump

摘要

A plug-in pump (2) for a common-rail system has a pump housing (7) with a cylinder formed therein and a piston (24) guided therein, a fuel inlet (33) and a fuel outlet (36). The pump housing (7) further has a plug-in section (8) for introducing the pump housing (7) into an opening (10) of a motor component (6) and a flange (12) delimiting the plug-in section (8) for fastening the pump housing (7) the engine component (6) has. For cooling the plug-in pump, the pump housing (7) has at least one flow channel (38) with a separate fluid inlet (40, 48) and a separate fluid outlet (41, 52). The fluid inlet (40, 48) can be connected to a fluid-emitting line of the internal combustion engine and the fluid outlet (41, 52) can be connected to a fluid-receiving line of the internal combustion engine.
