Abstract:
1. Hydraulic motor with tangential pistons acting on eccentric shafts arranged in a planet position with respect to a driven shaft, comprising: a driving body including 3 or more shafts arranged in a planet position and, in a tangential position thereto, two for each shaft, of pistons, cylinders and associated organs, into which, through a cavity with angular geometry defined in contact with the fixed part of the motor, a pressurized hydraulic fluid is inserted generating an axial thrust, which, by reacting on fixed parts also arranged in a planet position alternated with the shafts, produces a torque on the planet eccentrics wherein hydraulic distribution devices are at least partially rotatory with respect to driving means; wherein on both longitudinal ends, to two toothed gears, an outer gear with inner toothing as fixed part and an inner gear with outer toothing as driven gear, which, by meshing with the driving planet shafts, build a planetary gearing and transmit the torque to at least one between the driving planet carrier body and the inner driven gears.
