Abstract:
1. A system to recapture energy of a hydraulic motor, the system comprising: a primary tank containing fluid at an operating pressure, the fluid to circulate through the system; an output shaft; a hydraulic motor, wherein the fluid at the operating pressure flows through the hydraulic motor to rotate the output shaft; a flywheel adapted to rotate about the output shaft; a supply pillow block to support a first side of the flywheel about the output shaft; a return pillow block to support an opposing second side the flywheel about the output shaft; a plurality of reciprocating pistons mounted about the periphery of the flywheel to recapture energy when the flywheel is rotating under its own rotational inertia; a roller configured to sequentially engage each piston of the plurality of pistons as the flywheel rotates to increase the pressure of the fluid exiting the hydraulic motor by compressing the fluid when each piston is engaged by the roller; a plurality of cylinders, wherein each cylinder is adapted to slidingly engage a respective piston; a plurality of cylinder supply lines, wherein each cylinder supply line is in fluid communication with a respective cylinder of the plurality of cylinders; and a plurality of cylinder return lines, wherein each cylinder return line is in fluid communication with a respective cylinder of the plurality of cylinders.
