Abstract
An arrangement with a height-adjustable component includes an approximately vertically extending upright which bears the component, the upright including a pneumatic spring. The pneumatic spring has a cylinder having a bottom end connected to a fixed part of the arrangement. A piston displaceably arranged in the cylinder subdivides the cylinder into a bottom cylinder chamber and a top cylinder chamber and has a piston rod at one end. The piston rod projects through the top cylinder chamber and is guided out of the top end of the cylinder and bears the component at its free end. The top and bottom cylinder chambers are filled with a gas filling, under positive pressure, which subjects the piston to an upwardly directed push-out force corresponding approximately to the opposing weight-induced force of the component. A valve allows a gas flow from the top into the bottom cylinder chamber and blocks the same in the opposite flow direction. A manually actuable connecting valve selectively connects the bottom and the top chambers.
