摘要

System of modular elements for Making Connections and hinged WATERTIGHT, crossed by several separate steps of a pressure Fluid.It consists of a pair of Base Elements, the first of which essentially comprises a Cylindrical Block ring (24), whose axial Cylindrical boring (28) presents a series of Gorges interior circular (28a, 28B and 28C, 28D and 28E), each of these Gorges Communication respec Tiva with a DUCT (24a, 24B and 24c, 24D, 24E) through the Block (24),And a Second base Member comprising a Cylindrical Journal (38) whose Outer diameter is the diameter of the boring (28) of the First Base Element, so that said Journal (38) coupling of stagnating in the first element.
