Abstract
The invention relates to a radial piston pump having external loading. Said radial piston pump has an inner eccentric which is attached to a rotatable driveshaft, a cylinder block which has positionally fixed cylinder bores aligned radially with respect to the driveshaft, and displacement pistons which are mounted in a longitudinally movable manner in the cylinder bores, with the displacement pistons having a piston head with a short casing height, and being mounted with their piston base on the eccentric, in such a way that the piston head, during its longitudinal movement, pivots in a predetermined angle range &r about the longitudinal central axis of the associated cylinder bore.
