A plug-in pump for a common-rail system has a pump housing having a cylinder formed therein and a piston guided in the cylinder, a fuel inlet, and a fuel outlet. The pump housing also includes a plug-in section for inserting the pump housing into an opening of an engine component, and a flange that delimits the plug-in section, for fastening the pump housing to the engine component. To cool the plug-in pump, the pump housing has at least one flow duct with a separate fluid inlet and a separate fluid outlet. The fluid inlet is connectable to a fluid-discharging line of the internal combustion engine, and the fluid outlet is connectable to a fluid-receiving line of the internal combustion engine.

1. A plug-in pump for a common-rail system, the plug-in pump comprising: a pump housing having a cylinder formed therein,a piston guided in the cylinder,a fuel inlet, anda fuel outlet,wherein the pump housing further includes:a plug-in section configured to be inserted into an opening in an engine component, anda flange that delimits the insertion of the plug-in section into the opening in the engine component,at least one flow duct having a flow duct fluid inlet and a flow duct fluid outlet,wherein the flow duct fluid inlet is configured for connection to a fluid-discharging line of the internal combustion engine and the fluid outlet is configured for connection to a fluid-receiving line of the internal combustion engine; anda first fluid connection of the fluid-discharging line in a connecting region on the engine component,wherein the fluid inlet is disposed on the flange and aligned to the first fluid connection when the plug-in pump is mounted on the engine component. 2. The plug-in pump of claim 1, wherein the fluid inlet has a hole which is arranged in a region which is averted from the flange and which can be connected to a connection structure. 3. The plug-in pump of claim 1, wherein the fluid outlet is a hole which is arranged in a region which is averted from the flange and which can be connected to a connection structure. 4. The plug-in pump of claim 1, wherein the flow duct has an at least partially circumferential groove which can be sealed off by a circumferential seal over the flange on the engine component. 5. The plug-in pump of claim 1, wherein a second fluid connection is arranged in a connecting region on the engine component, said second fluid connection being in alignment with a fluid outlet on the flange when the plug-in pump is mounted on the engine component. 6. An engine arrangement, comprising: an internal combustion engine, anda common-rail system, comprising:a plug-in pump comprising:a pump housing having a cylinder formed therein,a piston guided in the cylinder,a fuel inlet, anda fuel outlet,wherein the pump housing further includes:a plug-in section configured to be inserted into an opening in an engine component, anda flange that delimits the insertion of the plug-in section into the opening in the engine component,at least one flow duct having:a flow duct fluid inlet connected to a fluid-discharging line of the internal combustion engine, anda flow duct fluid outlet connected to a fluid-receiving line of the internal combustion engine; anda first fluid connection of the fluid-discharging line in a connecting region on the engine component,wherein the fluid inlet is disposed on the flange and aligned to the first fluid connection when the plug-in pump is mounted on the engine component. 7. The engine arrangement of claim 6, wherein the fluid-discharging line and the fluid-receiving line are constituent parts of a cooling circuit of the engine. 8. The engine arrangement of claim 6, wherein the fluid-discharging line and the fluid-receiving line are components of an oil circuit of the internal combustion engine. 9. The engine arrangement of claim 6, wherein the fluid inlet has a hole which is arranged in a region which is averted from the flange and which can be connected to a connection structure. 10. The engine arrangement of claim 6, wherein the fluid outlet is a hole which is arranged in a region which is averted from the flange and which can be connected to a connection structure. 11. The engine arrangement of claim 6, wherein the flow duct has an at least partially circumferential groove which can be sealed off by a circumferential seal over the flange on the engine component. 12. The engine arrangement of claim 6, wherein a second fluid connection is arranged in a connecting region on the engine component, said second fluid connection being in alignment with a fluid outlet on the flange when the plug-in pump is mounted on the engine component.
