A thin-walled steel tubing is to be constructed with a double cone coupling nipple for the tight screwed connection with a counterpart by way of a cap screw in a crack-resistant manner. The steel tubing is thin-walled and constructed of high-strength steel. With respect to the remaining tubing area, the nipple has at least partially at least approximately a double wall thickness. The steel tubing is not soft annealed at any point including the whole area of the nipple. With respect to the material, the contact surfaces of the nipple are harder than the surfaces of the countercontact. The cone angle of the sealing surface of the nipple measures over 100.degree..

In an arrangement for controlling the flow of compressed air from a cylinder of a Diesel engine which includes a decompression valve mounted on a cylinder to permit the discharge of compressed air from the cylinder into a discharge passage, the decompression valve is operable by high pressure fuel admitted to an operating cylinder of the decompression valve via a control line including a magnetic control valve for the admission of fuel from a high pressure fuel distribution duct from which fuel is also supplied to the engine fuel injectors via an injection pipe which also includes a magnetic control valve, and both control valves are operable by a control unit which independently energizes the magnetic control valves.
