- 1 - A B S T R A C T (See Fig. 1) In conjunction with a gas suspension for vehicles, specifically for railway vehicles, a double-acting relief valve (1; 53) is provided in the connection between two spring bags (3, 5) located transversely opposite to the vehicle longitudinal centre-line between the vehicle body and the running gear and, when the pres- sure decreases in one of the spring bags (3, 5) below a predeterminable level assists in interconnecting the two spring bags and, preferably, in deflating an intact spring bag through the other burst spring bag. The relief valve (1; 53) is provided either with two check valves (11, 13) acting against each other above a predeterminable spring bag pressure with differential pressure behaviour or with two pressure- balances stop valves (55, 77) the check valves or pressure-balanced stop valves being capable of being moved under the action of a spring device into an open position establishing a constant connection between the spring bags (3, 5) if the pressure of the spring bag subject to a pressure drop acting against the spring device falls below the predetermin- able pressure level.
