GRAVITATIONAL ENGINE Russian patent published in 1994 - IPC

FIELD: converting gravitational energy to mechanical energy. SUBSTANCE: under the action of gravity pistons 26-29 of the same masses affect opposite cranks 12-15 arranged at the same distances from the rotation center. In so doing, the cranks are affected by the same pressures and crankshaft 11 is at rest. When fluid is fed to the hydraulic unit of one of the pistons 26-29 the pressure which applied to the crank is reduced by 6-7 times. As the result, a force difference occurs and crankshaft begins to rotate resulting in feeding fluid to the hydraulic units of those pistons which moves upward and draining fluid from them. The valve gearing provides a constant force difference applied to opposite cranks and, hence, rotation of the shaft. Flywheel 16 is accumulated the energy of rotation of the crankshaft 11 and takes the pistons out of the top and bottom dead centers. EFFECT: enhanced efficiency. 4 cl, 53 dwg
