Abstract
The invention specifies a hydraulic vane-type machine () having a stator () and having a rotor () which has multiple vanes (), each of which vanes is radially displaceable in a guide () in the rotor (), bears against an inner circumference () of the stator (), and, together with the rotor (), the stator () and in each case one side wall () at each axial end of the rotor (), delimits working chambers whose volumes vary in the event of a rotation of the rotor () relative to the stator (). It is sought to obtain a certain degree of freedom for the design of the inner circumference. For this purpose, it is provided that each vane () has, on its radially inner side, an abutment surface () which bears radially at the outside against a cam disk ().
