An apparatus for managing liquid under pressure comprising a first volume (connected to 5a'' or 5b'', respectively) adapted to contain liquid at a first pressure, a second volume (connected to 5b'' or 5a'', respectively) adapted to contain liquid at a second, lower, pressure and means (68-77) to receive and store energy derived from said first volume as a result of said first volume containing liquid under said first pressure and use said stored energy to increase the pressure in the second volume. |
