Abstract: The invention relates to a high pressure pump for a common rail pump system and to a common rail pump system. A high pressure pump (2) for a common rail pump system comprises a pump body (4) having a cylinder (6) with a piston bore (8) and a piston (10) reciprocally driven in the piston bore (8) by an eccentric to pressurize fuel in the cylinder (6). The piston (10) comprises an inner end (12) located in the piston bore (8) and an outer end (14) outside the piston bore (8). A bellow (20) having a first opening (22) and a second opening (24) is arranged between the piston (10) and the pump body (4), wherein the piston (10) extends through the first opening (22) and the second opening (24), wherein the bellow (20) is connected to the pump body (40) such that the first opening (22) is sealed on the pump body (4, 50) and wherein the bellow (20) is connected to the outer end (14) of the piston (10) such that the second opening (24) is sealed on the piston (10). This prevents mixing of engine oil and fuel, when the pump is directly attached to an engine. The bellow may be connected to a drainage line over a one-way valve.

Abstract: The invention relates to a roller (26) for a roller plunger (20) of a high pressure fuel pump (14), which is designed as a composite roller (28) and has a first material (40) for forming a first composite roller region (38) and a second material (44) for forming a second composite roller region (42). The first material (40) and the second material (44) are connected to each other to form a composite roller volume element (46) and the first material (40) is lighter than the second material (44). The invention further relates to a roller plunger (20) having the roller (26), a high pressure fuel pump (14) having the roller plunger (20), and an internal combustion engine (10), which has a crankshaft (12) and the high pressure fuel pump (14).

Abstract: A plug-in pump (2) for a common-rail system has a pump housing (7), with a cylinder formed therein and with a piston (24) guided therein, a fuel inlet (33) and a fuel outlet (36). The pump housing (7) furthermore has a plug-in section (8) for inserting the pump housing (7) into an opening (10) of an engine component (6), and has a flange (12), which delimits the plug-in section (8), for fastening the pump housing (7) to the engine component (6). To cool the plug-in pump, the pump housing (7) has at least one flow duct (38) with a separate fluid inlet (40, 48) and a separate fluid outlet (41, 52). The fluid inlet (40, 48) is connectable to a fluid-discharging line of the internal combustion engine, and the fluid outlet (41, 52) is connectable to a fluid-receiving line of the internal combustion engine.
