  • Pneumatic spring with integrated control valve
    Patent number: 6923433
    Abstract: Pneumatic spring with at least one control valve inside the pneumatic spring with control positions for feeding, blocking, and discharging compressed air, which valve is actuated by a control element also installed inside the pneumatic valve. The control element acts on one of the two pneumatic spring assemblies which can move relative to each other, namely, either on the outer tube or on the roll tube, where the control element has a working length which is shorter than the stroke length of the pneumatic spring and is pretensioned by a first spring against one of the pneumatic spring assemblies which can move relative to each other. The control element is supported in a floating manner relative to the pneumatic spring assemblies, and a second spring, the force of which is directed against the first spring, co-determines the position of the control element.
