Hydraulic motor, of the radial piston type and having an outer ring and an inner ring fitted one on the other, preferably with interleaving of a row of balls, characterized in that one of the rings, for example the outer ring, a cam ring is arranged, and the other ring, for example the inner ring, is provided with pistons and cylindrical distribution valves that govern the pistons, said pistons and distribution valves being adapted to cooperate, by means of the pressure of a liquid and optionally also by the action of an elastic force, with the cam ring, the angle between the piston and its distribution valve being chosen so that when the distribution valve passes through the position 0 of the cam ring, this takes place in a closed position of the valve, in which the pressure connection of the hydraulic motor is completely interrupted, and during the duration of the in this closing of the distribution valve, its plunger passes through a preferably flattened top or bottom of the cam ring.
