The invention relates to an external pressure fluid reservoir which has: an interior for receiving a fluid; an external wall to which, during operation, pressure is applied by an external pressure from the external environment and which separates the interior from the external environment in a fluid-tight manner; and a connection, which is provided between the interior and the external environment, for selectively exchanging fluid between the interior and the external environment; wherein the interior is formed by a bulk material filling and the wall is designed such that, during operation, said wall absorbs an external pressure exceeding the pressure in the interior and introduces it into the bulk material filling which in turn supports said wall, in its operating position, against the excess external pressure.
An external pressure fluid reservoir that has an interior in which a fluid can be accommodated, an outer wall subjected to an external pressure when in use, which separates the interior from the exterior in a fluid-tight manner, and a connection between the interior and the exterior for exchanging fluid between the interior and the exterior wherein the interior is filled with a bulk material, and the wall is designed to conduct external pressure exceeding that in the interior into the filling to withstand the external pressure when in use.
A method for producing an external pressure fluid reservoir that has an interior in which a fluid can be accommodated, an outer wall subjected to an external pressure when in use, which separates the interior from the exterior in a fluid-tight manner, wherein the interior is filled with a bulk material that supports the wall against an operational pressure difference, wherein first, a lower part of the external pressure fluid reservoir is produced, after which a pneumatic body is placed in the lower part and inflated to the intended size and shape of the interior, following which a skeletal structure and the wall are placed on the pneumatic body, wherein there is a hole at the top of the wall through which the bulk material can be introduced into the interior formed by the wall in a later step, to make it ready for use.
