Abstract of the Disclosure A method of producing a conduit intended for communi- cation with a plurality of working-medium sources, which conduit includes at least two connecting elements spaced apart along the length of the conduit and secured thereto. Each connecting element has a through passage communicating with the passage of the conduit and intended for connection with a source of a working-medium. The axis of the through passage is parallel to the axes of through passages of other connecting members and communicates with the conduit. To make such a conduit, a continuous-surface conduit is fed to a die-casting machine and is placed in its casting die, whose shape corresponds to that of connecting elements, in such a way that the axis of a core form- ing the through passage of each connecting element in the casting die is offset with respect to the conduit's axis with a distance therebetween being sufficient to obtain a strong and tight coupling of the connecting element with the conduit and provision of access for a working tool adapted to make a duct communicating the through passage with the conduit from the side of the former. Thereafter, the connecting elements are formed by a known method, and the coupling of the conduit with the connecting elements is obtained by means of a pressing force arising on the external surface of the conduit during the period of crystallization of the connecting element's material. A duct for communication of the through passage in the connecting ele- ment with the conduit passage is then made by a known method. The conduits produced by the method being claimed are success- fully used in diesel engines.
