ENERGY STORAGE DEVICE WITH A VARIABLE VOLUME CHAMBER

WIPO Patent Application WO/2023/183961

A1

A mechanical energy storage device is provided. The device comprises an expandable and contractable, sealed primary chamber (6) with a sealed variable internal volume containing an expandable/compressible primary fluid. An external medium or a secondary chamber (7) that resists expansion of the primary chamber (6) surrounds the primary chamber (6). An input mechanism (3, 4) that is actuated by an external force, manipulates formers (4) to transform the primary chamber shell (1) such that the sealed primary chamber (6) increases in volume and the expanding fluid contained within reduces in pressure causing a partial vacuum pressure differential between the fluid and the surrounding medium, or secondary chamber (7), allowing energy to be stored. When the external force is removed, the pressure differential works to decrease the volume of the sealed primary chamber (1) driving the output mechanism. A locking mechanism (90) allows for the device to store energy, for it to be decoupled and transported, and for the energy to be extracted later for various applications. In one embodiment, valves (8, 9) connected to the low pressure primary chamber (6) and the high pressure secondary chamber (7) can be used directly for additional applications.
