High-pressure pump, particularly radial piston pump for fuel injection system of compressed air internal-combustion engine, has pump groups and drive shaft with two bearing sections

摘要

The high-pressure pump (1) has pump groups (7,8,9) and a drive shaft (3) with two bearing sections. The drive shaft is mounted at the bearing sections, where an eccentric section is arranged between the bearing sections. A diameter (d) of the eccentric section is smaller than the diameters of the both bearing sections.
