Communication passage between two carriages of a rail vehicle, in particular of a high-speed rail vehicle

摘要

The passageway (10) has inner bellows (14) and an outer bellows (16) which is spaced from the inner bellows so as to define an interior space (17). The inner and outer bellows are each attached to the end faces of the vehicle. The inner and outer bellows are each designed in a box shape in their circumference. The interior space is operative to provide a partial pressure compensation.
