Abstract
A radial piston pump for supplying high fuel pressure in fuel injection systems of internal combustion engines that include a common rail. Pistons, which are disposed in a respective cylinder chamber, each of the pistons have a plate connected to one end. A center of each of the plates is embodied so that the stresses that occur in this location during operation are reduced. Reducing the stresses in each plate center advantageously extends the service life of each of the plates. A perfect function of the plate is thus assured, even at peak pressures of up to 2000 bar.
