Latest Patents

One of his notable inventions is the improved pistonless cylinder. This innovative design includes both single acting and double acting configurations, utilizing an Aramid fiber reinforced elastomer tubular. This material is highly stiff in the radial direction against radial expansion while remaining elastic in axial extension. The result is a completely sealed, extendable, and retractable pressure chamber that performs as well as, or better than, conventional hydraulic cylinders in terms of load-bearing capacities, maximum stroke distances, and service durability. This cylinder eliminates the need for pistons, piston rods, sealing seals, or oil-based hydraulic fluids, significantly reducing weight and fabrication costs. Additionally, it can operate using ordinary liquids, such as fresh water or seawater, and can function interchangeably as a hydraulic or pneumatic cylinder with minimal modifications.

Another significant patent is the pistonless cylinder used for offshore pile grippers. This design simplifies the original concept while maintaining the same benefits of weight reduction and cost efficiency. It also employs non-metal materials for the majority of its construction, further enhancing its practicality and sustainability.
