Abstract:
The invention relates to the automatic reloading of the gas space of a hydropneumatic accumulator. An apparatus for readjusting the load of the gas space includes a pressurized gas source connected via an air system to a loading check-valve and a reinjection valve controlled by a unit for calculating a cycle for reinjecting gas into the gas space.
