Abstract
Joint-type coaxial connection () to connect/disconnect to/from each other two elements (A, B) defining coaxial tubular pipes inside which a respective fluid flows. The connection () defines two respective coaxial paths for the passage of the fluid, one internal and one external, able to be selectively opened/closed substantially simultaneously so as to connect pairs () of tubular pipes, respectively inner and outer. In the connection step the two elements (A, B), located coaxial and with the front faces in contact, have a reciprocal approaching travel with the sealing means () which close every passage between the inner pipe and the outer pipe, and between the outer pipe and the part of the joint outside the outer pipe, before achieving the reciprocal fluid-dynamic continuity of the two coaxial pipes of the connection.
