Abstract (en)
[origin: US4606376A] A self-contained integral accumulator assembly includes a two-part housing joined by a central partition. One housing part encloses high pressure nitrogen. The other housing part encloses a volume which is divided by a flexible bladder into an oil chamber and a precharge chamber. The partition includes a recharge passage and a recharge valve for automatically repressurizing the precharge chamber from the high pressure nitrogen when the precharge pressure falls below a predetermined pressure.
