  • Connection assembly for conduits
    Patent number: 6579110
    Abstract: The invention relates to a connection assembly for conduits (3, 4; 7, 8) which are arranged coaxially inside one another and which accommodate the supply flow and return flow of a cryogenic medium. Said assembly comprises a first and a second coupling half (1, 2) which can be connected to one another in a sealed manner, whereby an inner conduit (4; 8) in each coupling half (1, 2) ends in a first conical sealing surface (9; 10) and an external conduit (3; 7) in each coupling half (1, 2), which encompasses the inner conduit (4; 8), ends in an additional conical sealing surface (11; 12) that is positioned outside the first conical sealing surface (9; 10) in the radial direction. In order to establish an electrical connection simply and reliably, at least one electrical contact (18, 20) is provided within the additional conical sealing surface (11; 12) in each coupling half (1, 2).
