<p>A hydraulic motor, particularly for driving rotational tools, comprising a chamber (1), which, at least at a part of its internal surface, has a shape of a solid of revolution, and is provided with a fluid inlet opening (3) and with at least one fluid outlet opening (6). In the chamber (1) is arranged a rolling rotor (4), represented by a body of a rotary shape, which is supported on a holding device in a manner enabling precessional motion of the shaft (5) of the rolling rotor (4). Each fluid outlet opening (6) is connected by a line (7) with a fluid tank (12). Using e.g. a valve (8) in the lines (7) back to the fluid tank, a part of the fluid can be directed at a working piece (13). This renders the fluid-driven rolling rotor machines suitable for both the dry working processes and for the wet working processes.</p> |
