    摘要: A rail vehicle spring system has a spring strut, arranged between a bogie and carriage body of the rail vehicle, and includes a cylinder and a piston in the cylinder. Piston spaces are defined below and above the piston head. The piston or the cylinder is connectable with the bogie, while the other component is connectable with the carriage body. A spring cushions the body relative to the bogie, and a hydraulic system is connected with at least one of the piston spaces to charge the space with hydraulic medium. The spring surrounds the cylinder and is contracted by the piston when an excess pressure exists in the lower piston space with respect to the upper piston space, and an entraining element is adjoined by the spring. Only when an excess pressure exists in the lower piston space does the piston rod exerts a force on the entraining element.

    摘要: The disclosure relates to a flight control system comprising at least one hydraulic servo actuator, wherein the servo actuator includes a two-stage electrohydraulic servo valve, wherein the servo valve comprises a pilot stage in which the control current is translated into a hydraulic control pressure, and a power stage in which a valve slide is moved in response to the control pressure in order to adjust the throughflow direction and throughflow cross-section of the valve. The disclosure furthermore relates to an aircraft comprising such a flight control system.
