Hydraulic hybrid systems, that are able to recuperate energy, require a pressurized tank to ensure the back flow ability. Usually, the pump suction port cannot be connected directly to the elevated pressure. Thus both, ambient pressure tank and pressurized tank are required with auxiliary components. This note presents a concept, where the pump rotary shaft seal is replaced to withstand the elevated pressure in order to get rid of the ambient pressure tank. Successful implementation of the concept encourages to further apply it.
