Radial piston pump i.e. high-pressure fuel pump, for e.g. diesel engine of common rail system, has pump unit arranged radially within cam ring of drive unit, where cam ring rotates around rotation axis for driving pump unit
Radial piston pump i.e. high-pressure fuel pump, for e.g. diesel engine of common rail system, has pump unit arranged radially within cam ring of drive unit, where cam ring rotates around rotation axis for driving pump unit
The pump (10) has a pump unit (12) with a cylinder (31) comprising a cylinder longitudinal axis (Z) and a cylinder area (32), and a pump piston (30) arranged in the cylinder area in an axially movable manner. A drive unit (14) drives the pump unit, where the pump unit is arranged radially within a cam ring (17) of the drive unit. The cam ring rotates around a rotation axis (R) for driving the pump unit. The cam ring exhibits a cam that is arranged on an inner side of the cam ring, where the cam cooperates with the pump piston for driving the pump unit.
