ABSTRACT:
A gas-operated spring for the mutual support of two oscillating elements moving relative to one another, for which sensor-controlled (9, 10) first and second devices (1, 2) are provided, which bring about the blowing out of excess compressed gas from the gas-operated spring or the feeding in of additional compressed gas into the gas-operated spring (11) through the activation of valves (3, 4, 5). To prevent a mutual impairment of function, the first device (1) is active only for pressure changes of a frequency above a threshold value and the second device (2) only for changes in the mutual correspondence of the two elements (7, 8), which have a frequency below the threshold value.
