Abstract: The present invention relates to an accumulator capable of improving a connection structure of an upper shell and a lower shell and accurately connecting the upper shell and the lower shell in an accurate position. The present invention comprises the lower shell, the upper shell, a diaphragm, an O-ring, and a fixing ring. An oil inlet hole is formed in a lower side of the lower shell. The upper side of the lower shell is composed of an opened hemisphere shape. A connection stepped unit is formed on an inner side of the lower shell. The upper shell is positioned on the upper side of the lower shell and comprises a gas discharge valve on the upper side. The upper shell in which a connection protrusion corresponding to the connection stepped unit is formed inside is inserted into the lower shell. The diaphragm is connected between the outer circumference surfaces of the upper shell and the lower shell and divides the space between the upper shell and the lower shell into a gas chamber and an oil chamber. The O-ring is formed between the connection stepped unit and the connection protrusion and prevents the leakage of the oil of the oil chamber from the outside. The fixing ring is arrange on the upper side of the connection protrusion of the upper shell and fixes the upper shell and the lower shell by connecting the outer circumference surface and the inner side of the lower shell.

Abstract: An accumulator designed to damp the pressure waves of the hydraulic shocks originating in a downstream section of a duct is arranged inside the duct, with the opening of the accumulator pointing downstream. This results in excellent absorption of the pressure wave and protection of the circuit from possible accumulations of air, water or ice, there being no areas where the flow stagnates. Immersing the accumulator in the flow also makes it possible to ensure that the equipment is protected in the event of a fire.

Abstract: A system filled with a fluid, designed for underwater applications, in which the interior of a housing and/or tank forms a fluid region which is sealed with respect to the surrounding seawater region, includes at least one hydraulic pressure compensation device, which at least raises the pressure level of the fluid region to the ambient pressure prevailing in the seawater region. The pressure compensation device is constructed in two stages in such a way that at least one store having a flexible wall region and at least one piston store having a displaceable piston are arranged in series. The use of the pressure compensation device to pressurize at least one housing filled with fluid for a hydraulic actuating shaft is also proposed.

Abstract: The present invention is a distributed piston elastomeric accumulator which stores energy when its elastomeric member stretches from its original length in response to the flow of a pressurized fluid. The stored energy is returned when the fluid flow is reversed and the accumulator discharges the fluid as its elastomeric member returns to its original length and moves the piston to its initial position. At least one part of the novelty of the invention is that the accumulator is not subject to radial strain gradients and the accumulator allows for precise pressure and linear position measurements. Accordingly, the invention allows for optimization of the energy strain storage capacity of a given elastomer.

Abstract: A system for determining the location of a movable element within a container is provided in which a linear variable differential transformer (“LVDT”) is formed with the container and the movable element therein. The LVDT includes a coil assembly including a primary or excitation winding, a secondary or output winding, and a movable element or core that is magnetically permeable. Measurement of an output signals allows for precise determination of the movable element location relative to the container. The system can be utilized to determine fluid volumes in accumulators used for controlling subsea equipment by monitoring the location of a movable element, e.g., a piston, within a hydraulic fluid accumulator.
