High pressure pump e.g. radial piston pump, for fuel injection system of air-compressing auto-ignition internal combustion engine, has drive shaft supported in housing part by slide bearing, and slide bearing injected into housing

摘要

The pump (1) has a housing part (5), and a drive shaft (6) supported in the housing part, and a pump assembly (13) driven by the drive shaft. The shaft is supported in the housing part by a slide bearing (7), and the bearing is injected into the housing. The housing part comprises a hole (32), and the bearing is made of thermoplastic resin or polyetheretherketone. A positive locking is formed between the slide bearing and the housing part. The housing part comprises a protrusion, and a material of the bearing is partially extended for form-fit connection of the part with the bearing.
