The motor (11) has a reverser (30) installed at the interior of a casing (12). Holes and grooves of the reverser control and switch the circulation of actuating fluid arranged between a sleeve (40) and a distributor (42) for alternatively and sequentially controlling the filling of one chamber and emptying of another chamber following which the distributor occupies a predetermined position. The distributor and sleeves define the position. A control unit controls rotation of the distributor according to displacement of the sleeve (38) integrated to a piston (24) including chambers (28, 29). |
