Abstract (en)
[origin: EP0592388A1] System for regulating the pressure level in a transverse suspension between bogie and coach body for railway vehicles, in which the bogie frame is connected to the coach body via at least two pneumatic spring elements, preferably pneumatic spring bellows which are connected to a compressed air source via control valves when the associated spring element experiences spring compression from a blocking basic position or are otherwise connected to the external air, the valves which are associated with the spring elements which act in opposition to one another being coupled in opposite directions and the control valves being capable of being actuated by means of at least one lever, the control valves (6) clearing a relatively small cross-section in a narrow area along both sides of the blocking position and clearing a large valve cross-section in an adjoining wider area on both sides and the blocking position of each valve (6) being achieved with a small spring compression of the associated spring element (4). <IMAGE>
