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.

A method of determining displacement of a radial piston machine (1) having adjustable eccentricity (e), the radial piston machine (1) having cylinders (2) arranged in a pivoting manner and having a drive shaft that drives an eccentric (5), the method comprising the steps of:
- measuring a pivoting angle (β) of the cylinders (2);
- and
- calculating the eccentricity (e) and hence a displacement (v) from the measured values for the pivoting angle (β), and
- determining a direction of rotation of the drive shaft for a course of a function (β=f(α)) of the pivoting angle (β), with the pivoting angle (β) being function of the rotation angle (α) of the drive shaft.
