A device for transmitting a hydraulic working pressure in a pressure fluid for pressure actuation of hydraulic devices for deep-water systems

A device for transmitting a hydraulic working pressure in a pressure fluid for pressure actuation of hydraulic devices for deep-water systems, in particular deep-water drilling, wherein in a cylinder assembly (1), a first pressure space (19) for the pressure fluid, one to change the volume of this pressure space (19) movable piston assembly ( there are 9, 11, 13) and at least a second pressure chamber (21) generating a working pressure in the first pressure space (19) movement of the piston assembly (9, 11, 13) is acted upon by the ambient pressure of the deep sea, is characterized that the cylinder assembly (1) associated with the pressure accumulator (37) is provided, whose movable separating element (41) from an actuating chamber (43) separates a connected to the raw water area (45) containing an operating fluid, and (with the second pressure chamber 21 ) is connected to this Beau means of the actuating fluid pressure with the deepwater fschlagen.
