Abstract
A hydro-pneumatic accumulator includes a housing defining a gas chamber for a compressible gas and a fluid chamber within the housing. A gas valve is in communication with the gas chamber via a gas passage. A check valve is provided within the gas passage and prevents gas from releasing from the gas chamber when the gas valve is removed, wherein the check valve is mechanically actuated to an open position by the gas valve in communication with the gas passage.
