<p>A hydraulic torsional motor, comprising a cylindrical housing (1), a cylindrical annular piston (2) which can be moved axially inside the housing (1), but which is prevented from being rotated relatively thereto, and a cylindrical rotor (3) situated inside the piston (2), coaxially therewith, and which can be rotated about its longitudinal axis relatively to the housing (1) by axial movement of the piston (2), but which is prevented from moving axially, whereby an annular chamber (29) in which the piston (2) is situated is closed by end closures and has a greater length than the piston and is coupled to a supply of a drive fluid for axial movement of the piston (2) in both directions, and whereby meshing members (4) causing rotation of the rotor (3) protrude into inclined recesses (5). The inclined recesses (5) are situated in the piston (2), and the meshing members (4) protrude radially from the rotor (3).</p> |
