High-pressure pump, particularly radial piston pump or in-line piston pump for fuel injection systems of air-compressing, self-ignited internal combustion engines, has pump assembly and drive shaft

摘要

The high-pressure pump (1) has a pump assembly (8) and a drive shaft (3). The drive shaft has a cam (7) which is assigned to the pump assembly. The pump assembly has a roller (30) which runs on a cam running surface (32). The running surface of the cam is formed in concave or convex manner. A roller running surface (31) is adjustably formed at the concave or convex arrangement of the running surface of the cam.
