<p>The invention concerns a hydraulic motor of which the characteristics have been improved in the way that auxiliary passages (13) intended to supply oil in under the action members (6) in order to seal these against the guiding surface have been placed in peripheral direction on either side of the sealing region (15) and are disposed to extend in a motor with two chambers 12 to 25 degrees, and in a motor with three chambers 5 to 12 degrees, towards the working region (19). In order to ensure the oil supply and exit, and to preclude occurence of pressure shocks, the margin of the stator (1) adjacent to the valve plate (5) comprises, in register with the supply/exit apertures (12), grooves (17) which extend, as viewed peripherally, over the entire transition region (18).</p> |
