Abstract (en)
[origin: WO2011128149A1] A high-pressure pump (1) which serves, in particular, as a radial or in-line piston pump for fuel injection systems of air-compressing, auto-ignition internal combustion engines, comprises a pump assembly (6) and a drive shaft (7) which has at least one cam (10) which is assigned to the pump assembly (6). Here, the pump assembly (6) comprises a roller (31) which runs on a running surface (34) of the cam (10) and a roller shoe (30) which receives the roller (31). Here, at least one anti-corrosion layer is provided on the roller (31) and/or at least one anti-corrosion layer is provided on the roller shoe (30) and/or at least one anti-corrosion layer is provided on the cam (10). This can prevent oscillation crack corrosion occurring during operation, which corrosion can lead under loading to breakouts near the surface and, as a result, to failure of the high-pressure pump.
