    Abstract: A system for storing and releasing hydraulic energy having a controller, a pressure source, a bidirectional valve fluidly connected to the pressure source, an expandable vessel fluidly connected to the bidirectional valve having a plurality of axial folds between first and second ends, and a bidirectional port connected to the pressure source. As the plurality of axial folds expand, a contracted volume of pressure expands increasing stored hydraulic fluid energy in the expandable vessel. As the plurality of axial folds contract, the expanded volume reduces, releasing stored hydraulic fluid energy to nearby subsea equipment on demand as changes in hydraulic fluid energy requirements for the subsea equipment changes. Simultaneously, hydrostatic seawater pressure of seawater on the expandable vessel is counteracted with the hydrostatic pressure of fluid inside the expandable vessel.

    Abstract: A hydraulic damper disposed in a discharge-side passage of a hydraulic pump comprises a bladder made of elastic material and formed into a cylindrical shape, a core, and a plug. The bladder includes a spherical closed end portion at its one end and an open end portion at its the other end. The open end portion includes an annular flange portion extending outwardly in the radial direction. The core includes an inserted portion to be inserted into the bladder and an annular flange portion extending outwardly in the radial direction so as to contact with an end face of the open end portion of the bladder. The inserted portion has a large-diameter portion, a small-diameter portion and a gradually-changing diameter portion formed between the large-diameter portion and the small-diameter portion and forming an air chamber in the bladder together with the small chamber.

    Abstract: The invention is a combination accumulator and reservoir which stores energy when the accumulator deforms from its original shape in response to the flow of a pressurized fluid from the reservoir. The stored energy is returned when the fluid flow is reversed and the accumulator discharges the fluid and returns to its original shape. At least one part of the novelty of the invention is that the accumulator and the fluid reservoir reside in the same housing such that the volume of each varies inversely. Accordingly, the invention is more compact and weighs less than conventional accumulators. Another feature of the invention is that fluid is located around the bladder accumulator to lubricate contact between the bladder and sides of the reservoir.
