Abstract

En invertert akkumulator til undervannsbruk omfatter et luffylt lavtrykkskammer (1) som senkes ned mot sjøbunnen. Kammeret er koblet til en stempel/sylinderanordning (2). Trykkforskjellen vil kunne utløse et stempelslag som brukes til å utføre et arbeide, f.eks. åpne eller lukke en ventil 3.An inverted accumulator for underwater use comprises a air-filled low pressure chamber (1) which is lowered to the seabed. The chamber is connected to a piston / cylinder device (2). The pressure difference can trigger a piston stroke used to perform a job, e.g. open or close a valve 3.
