Abstract: Disclosed is a gas spring/damper unit (1) having at least one movably mounted displacement piston (2) and two displacement chambers (3, 4) whose volume increases or diminishes according to the direction of travel of the displacement piston (2) and which are interconnected via overflow ducts (6, 7) in which throttle valves (16, 16?, 16?, 17, 17?, 17?, 17??) are disposed. Several throttle valves (16, 16?, 16?, 17, 17?, 17?, 17??) having different valve characteristics are positioned so as to be effective in one direction of flow. One throttle valve (17) is designed for damping eigenfrequencies ranging from 1 to 1.5 Hz while another throttle valve (17?) is designed for damping eigenfrequencies ranging from 10 to 40 Hz.

Abstract: A pneumatic suspension and damping arrangement (100) is fixedly mounted on the chassis at the upper region and to the wheel mount at the lower region thereof. The arrangement includes two hermetically closed air springs (101, 102) filled with pressurized gas, whose volumes can be changed and which are connected via an air connection (134) to a pressurized gas source. The air springs are each enclosed by a movable wall formed by a flexible member (116, 124) and each roll off on a roll-off contour and are connected to each other via a throttle element (108) through which the gas can flow in two directions. The air springs are arranged one above the other and the roll-off contour of the first air spring (101) is defined in such a way by the second air spring (102) that the first air spring (101) rolls off on the second air spring (102). A connecting element of the upper cover (104) ) with the roll-off piston (128) of the second air spring (102) runs outside of the two air springs (101, 102).
