Beschreibung
Zusammenfassung:	The invention relates to a high pressure pump (1) for a fuel injection device of an internal combustion engine, which has a power unit (25) arranged in a housing (2) having a drive shaft (3) having at least one cam (4) and mounted via an axial bearing in the housing (2) and a plunger assembly (22), and at least one pump piston (7), which is driven by the rotation of the drive shaft (3) around a rotation axis (21) via the at least one cam (4) arranged on the drive shaft (3) and the plunger assembly (22) arranged on the at least one pump piston (7) in a stroke movement in a substantially radial direction to the rotation axis (21) of the drive shaft (3), wherein the axial bearing is designed as an axial slide bearing (27, 27').
