Abstract

The arrangement has an eccentric shaft (3) with an eccentric section (7) with an eccentric sleeve mounted on it so as to be rotatable with respect to the sleeve by an angle of less than 360 degrees, preferably less than or equal to 180 degrees. It has a stop arrangement (15) that limits the rotation of the eccentric sleeve relative to the eccentric section. An independent claim is also included for a radial piston pump.
