Fuel i.e. diesel, pump for use as pump arrangement for fuel injection systems of air-compressing, self-igniting internal-combustion engines, has clutch arranged at exterior of shaft, where surface is arranged between clutch and housing part

摘要

The pump (1) has a pump part (2) designed as a low-pressure pump, and another pump part (3) designed as a high-pressure pump. The former pump part is separated from the latter pump part by a housing part (16). A clutch (27) is arranged in the former pump part and at exterior (34) of the pump shaft. An axial running surface (31) is provided for the clutch at the pump shaft. The axial running surface is arranged between the clutch and the housing part, where the clutch is formed as a driving clutch. The pump shaft is projected by an opening (23) in the housing part. The low pressure pump is designed as an external gear pump.
