The movement compensator has a first pipe connected to the supply pipe by a connecting flange that permits rotation of the first pipe and the supply pipe relative to one another, and a second pipe connected to the first pipe by another connecting flange that permits rotation of the first pipe and the second pipe relative to one another. The second pipe is further connected to the stationary supply pipe by a third connecting flange that also permits rotation of the second pipe and the stationary supply pipe relative to one another.
