Abstract (en)
[origin: WO8602695A1] In order to be able to connect a boring line with a tube or casing with the aid of pressurized coupling pieces, without direct access to the point of connection, an operating system (40) is envisaged which contains a multi-way valve (48), that can be switched by a positioning drive (46), the valve being equipped with at least three connections (51, 52, 53), whereby a coupling (47) operating in one direction is arranged between the movable part of the multi-way valve (48) and the positioning drive (46). In particular, a plurality of support elements (34) and locks (24), as appropriate, can be provided as coupling pieces, at a distance in the axial direction of the device.
