High-pressure pump, particularly radial or reciprocating-piston-pump for fuel injection plant of air-compressing, self-igniting internal combustion engines, has pump assembly and drive shaft

摘要

The high-pressure pump (1) has a pump assembly (13) and a drive shaft (6). The pump assembly is assigned to a cam (9). A roller shoe (26) has a wear resistant part (35), on which a roller (25) for transmitting the driving force from the cam of the drive shaft partially lies on a pump piston (16).
