<p>A hydraulic machine (1) is disclosed, having an annular gear (3) with internal teeth (5) and a gearwheel (2) with external teeth (4) mounted eccentrically therein, the internal teeth (5) comprising one more tooth than the external teeth (4) and the teeth of at least one set of teeth being formed by rotatably mounted rollers (6). It is desirable in such a machine for the internal seal to be improved and wear to be reduced. To that end, each roller (6) has in its surface at least three axially parallel recesses (8), in which the teeth (4) of the other set of teeth engage.</p> |
