Abstract
The present invention is a cryogenic tank assembly that includes a vessel with a cryogen space capable of storing a cryogenic fluid at an initial pressure. The assembly further includes a pump that has an intake opening so that it can receive a quantity of the cryogenic fluid, pressurize it to a pressure above its storage pressure and deliver it to an accumulator within the cryogen space. The accumulator includes a storage volume to hold the pressurized fluid so that it is available depending on the demands of the end user.
