- a high-pressure pump for a fuel injection of an internal combustion engine has a pump housing, in which a pump element is arranged, which comprises a driven by a drive shaft in a stroke pump piston.
- the pump piston is slidably guided in a cylinder bore of a part of the pump housing and limited in this one pump working space.
- the pump piston is supported indirectly via a hollow cylindrical plunger on the drive shaft, wherein the plunger is slidably guided in a bore of a part of the pump housing in the direction of the longitudinal axis of the pump piston.
