Abstract (en)

[origin: EP1072791A2] The hydraulic motor consists of a cylinder block (6), forming a primary group of cylinders (12A), arranged radially around the axis of rotation (10). A reaction element (4A) is mounted so as to rotate relative to the block around the axis of rotation. An internal distributor (16) of fluid is mounted fixed to the reaction element, so that the supply and exhaust to the cylinders can be achieved. A selector (34) is fitted to the cylinder block and allows communication to each cylinder through a communication pipe (40), according to the position of the piston.
