High pressure pump, particularly radial piston pump or in-line piston pump for fuel injection systems of air compressors or self-igniting internal combustion engines, comprises drive shaft that has cam attached to pump assembly

摘要

The high pressure pump (1) comprises a pump assembly (13), and a drive shaft (6) that has a cam (9) attached to the pump assembly. The pump assembly has a piston (16) and a tappet base (27), where the piston is driven indirectly by the cam of the drive shaft. The tappet base is formed asymmetric to an axis (17) of a guide hole (12) sectionally. The guide hole is adjusted in the design of the tappet base, and is formed asymmetric to its axis sectionally.
