  • Pneumatic springs and other telescopic systems
    Patent number: 4163970
    Abstract: A telescopic system formed of a relatively slidable plunger rod and cylinder is operated as a pneumatic spring equipped with an end-stroke electrically-actuated indicator. The plunger rod is fitted with a damping piston which is slidably mounted thereon between two stops secured thereto and used as valve members for partially obturating a groove formed on the piston face and communicating with an axial passage through the piston. The cylinder bottom and the slidable piston constitute the two associated contacts of an electric switch and are respectively connected to the terminals of an electric circuit energizing an indicator.
