Abstract

A machine for performing work at great depths utilizes the energy which is released when surrounding water masses at great hydrostatic pressure are admitted into a low pressure reservoir via a hydraulic motor (2). The machine uses a built-in low pressure reservoir (3) as a hydrostatic accumulator, the energy which is released when the surrounding fluid is admitted into the low pressure reservoir being determined by the product of the pressure difference and the internal volume of the low pressure reservoir. In a special version (Fig. 10) the machine is designed as a hydrostatic sampler which is particularly adapted for taking core samples or marine sediments on the seabed.
