Abstract:
PCT No. PCT/SE90/00565 Sec. 371 Date Mar. 18, 1992 Sec. 102(e) Date Mar. 18, 1992 PCT Filed Sep. 4, 1990 PCT Pub. No. WO91/04436 PCT Pub. Date Apr. 4, 1991.A device is adapted for coupling together two vacuum lines, such that when coupled the lines can be rotated relative to each other. Each of the vacuum lines includes two mutually concentric pipes which define a vacuum space therebetween. The coupling device includes a first coupling part, a male part, on the one vacuum line, and a second coupling part, a female part, on the other vacuum line. Located between the male part and the female part is at least one sealing ring which is arranged so as not to come into direct contact with a cold or a hot medium flowing through the inner pipe. The invention also relates to male and female parts of the coupling device for coupling together vacuum lines which, subsequent to being coupled, can be rotated relative to each other.
