FIELD: engines and pumps.SUBSTANCE: variable-speed axial-piston hydraulic motor comprises cylinder block with pistons and balls resting on disc rigidly coupled with drive shaft. One wavy surface of the latter features maximum elevation angle at the center gradually decreasing toward disc edge. Sais balls cam simultaneously move from disc center to its edges and vice versa. Pump comprises also rotor, shaft, rocker, gears, and manifold with delivery and drain ducts. Proposed device can operate as variable-speed gear and motor-wheel.EFFECT: pump shaft rpm adjustment with no power loss.2 dwg |
