Abstract

A method of determining displacement of a radial piston machine (1) having adjustable eccentricity (e). The radial piston machine (1) includes cylinders (2) arranged in a pivoting manner and a drive shaft that drives an eccentric (5). The rotation angle of the drive shaft is labeled as α and the pivoting angle of the cylinders (2) is labeled β. The pivoting angle β is measured and from the measured values for the pivoting angle β, the eccentricity (e) and hence the displacement (v) are calculated.
