Abstract (en)
[origin: EP1508645A2] A piston-cylinder device (113, 114) is used to move a sleigh (112) supporting a coupling half-section. A pressure valve (119) which can be shut off is used to maintain a pressure in the piston, which is used to fix the two coupling half-sections together in the connected position. The device comprises a movable coupling half-section on a sleigh and a fixed coupling half-section.
