A radial piston pump for a high-pressure fuel supply in fuel injection systems of internal combustion engines, in particular in a common rail injection system, having a drive shaft which is supported in a pump housing and is embodied eccentrically or has cam-like protrusions in the circumferential direction. A plurality of pistons are disposed radially in given cylinder chambers relative to the drive shaft (4), and the pistons are movable radially back and forth in the respective cylinder chamber by rotation of the drive shaft. In carrying out the invention, a transverse force absorbing device is disposed between each piston and the drive shaft. This has the advantage that only forces in the longitudinal direction are brought to bear on the pistons. This means that virtually no moments act on the pistons.
