An emergency fluid exit arrangement of a cylinder piston device and a cylinder piston device with such an emergency fluid exit arrangement.

摘要

According to an illustrative example of the invention a gas spring is provided with an emergency exit permitting escape of pressurized gas in case of said pressurized gas exceeding a predetermined pressure. The emergency exit is provided by a radial bore (13) through the cylinder (1). This radial bore is covered unter normal conditions by a piston rod seal (6). This piston rod seal (6) is axially displaceable by said pressurized gas at said predetermined pressure such that the radial bore (13) is opened for escape of pressurized gas. <IMAGE>
