Abstract
A pneumatic cylinder having end position damping of the cylinder piston is controlled by means of a vent path and a control valve, the control valve comprises a control piston, the control side of which is pressurized by a pneumatic pressure which exists in a control chamber. The movement of the control piston into its closing position is pneumatically controlled by the increasing pressure in the damping chamber during the beginning of the damping. No additional components or controls are to be provided, so that the control of the end position damping occurs exclusively by the pressure conditions prevailing at the time when the damping begins.
