ABSTRACT:
A cylinder apparatus and a method of controlling the same allow an object to be moved at high speed and provide a decelerating force that can be changed with ease in conformity with the type of object. The apparatus includes a cylinder, a piston, an air supply source, a first pressure regulator for feeding compressed air of a first pressure into one chamber of the cylinder, a second pressure regulator for feeding compressed air of a second pressure into a second chamber of the cylinder, a first solenoid valve, a second solenoid valve, a deceleration-position sensor for sensing a position at which the piston begins deceleration, a stopping-position sensor for sensing that the piston is situated at an end of the cylinder, and controller for controlling the first and second solenoid valves.
