Abstract:
1. Joint-type coaxial connection to connect/disconnect to/from each other two elements (A, B) defining respective coaxial tubular pipes inside which a respective fluid flows, said connection defining, when said elements (A, B) are connected to each other, two respective coaxial and substantially rectilinear paths for the passage of a respective fluid, said two coaxial rectilinear paths being able to be selectively opened/closed substantially simultaneously, one path (C 2 ) being internal and the other (C 1 ) being external, so as to connect pairs ( 11 a , 11 b ; 12 a , 12 b ) of tubular pipes, respectively an outer pipe and an inner pipe, each pair ( 11 a , 11 b ; 12 a , 12 b ) being present in a respective element (A, B) and including respective interception means in the disconnected condition, characterized in that the first element (A) has elastically contrasted connection/disconnection means consisting of at least a first toric crown ( the second element (B) has respective thrust means cooperating with a relative elastically contrasted means ( wherein, in the passage of connection/disconnection of said elements (A, B), when said toric thrust means (
