Beschreibung
Zusammenfassung:	A hydraulic machine (1) comprising a housing (2) and a spool (3) arranged in the housing (2) rotatably about an axis or rotation (4) is described, wherein the spool (3) comprises a first circumferential groove (14), a second circumferential groove (15), a set of first axial grooves (16) connected to the first circumferential groove (14) and a set of second axial grooves (17) connected to the second circumferential groove (15), the axial grooves (16, 17) being arranged between the first circumferential groove (14) and the second circumferential groove (15) and the first axial grooves (16) and the second axial grooves (17) are alternately distributed in circumferential direction of the spool (3).In such a hydraulic machine the first groove (14) comprises a first bottom wall (19) between two first transition areas (20, 21) at the axial ends of the bottom wall (19), the first bottom wall (19) having a varying distance to the axis of rotation (4).
