Abstract: 852,889. Pneumatic springs. BOGE G.m.b.H. Jan. 4, 1957, No. 452/57. Class 108(3). A pneumatic spring is connected through valves 11, 14, to two gas containers 12, 15, respectively which are connected together through a compressor 28, the pneumatic pressure of the spring being higher than the pressure in the container 12 and lower than the pressure in the container 15. As shown, the pneumatic spring comprises a piston 1 slidable within liquid 6 in a cylinder 3, there being damping valves (not shown) in the piston 1. Pneumatic pressure is developed in a space 4 which is connected by the regulating valve 11 and a non-return valve 10 with the low pressure container 12, and by the regulating valve 14 and a non-return valve 13 with the high pressure container 15. The latter also contains liquid 19 which is connected by a conduit 27 and pump 29 with liquid 18 in the container 12. A membrane may be used to separate the liquid and air in the spring. Floats may be used to regulate the oil volume. Means may be provided to vary the quantity and the pressure of both gas and liquid in the spring and in the containers.
