  • Radial hydraulic motor
    Patent number: 9080559
    Abstract: A radial cylinder hydraulic motor includes oscillating cylinders, in proximity to the outer skirt to the crown or star of cylinder-piston groups; the pistons of the said groups slide on a crankshaft or eccentric shaft, or on interposed organs concentric to it, and create alternate motion in the oscillating cylinders. A respective surface of oscillation for each cylinder of the said groups, in proximity to the outer skirt, is constituted by a portion of cylindrical surface with axial direction parallel to the axis of rotation of the crankshaft or eccentric shaft and positioned in the part of skirt including the diametral plane of lying of the said crown or star of radial cylinders.
