An end cock of a brake line comprises a body 1 with a fitting 2, with rear end 3 and two side walls 4 and 5, a manual drive 6 and a gate 7. On one of the side walls of the body 1 a guiding lug 8 is located with upper additional lug 9 adjacent to the outer surface of upper part of its generatrix abutting with lower additional lug 10 adjacent to the outer surface of the lower of generatrix of guiding lug 8. The upper 9 and lower 10 additional lugs are located from the side of rear end wall 3. In the upper additional lug 9 there is a through hole 17, in the lower additional lug 10 is made a through hole 19 coaxial to the through hole 17 of upper additional lug, each of which penetrates into the cavity of guiding lug 8 where a bushing 14 of a crank 13 is installed, to allow the installation of a fixing element 18 of bushing 14, thus improving the service life of the end cock of the brake line of railway rolling stock due to safe conducting assembly-disassembly works relative to the end cocks. |
