This article describes the application of a dash pot 1 and adjustable leak valves 2 and 3 to obtain non-linear deceleration rates in a parts-handling machine subsystem. The adjustable valves are installed in the input and output ports of a buffer chamber 4. The valves regulate the amount of air that will enter the buffer chamber and the amount of air that will be exhausted from the chamber in each stroke of the subsystem. The input and exhaust valve settings can be determined empirically to obtain the desired deceleration pattern and then locked in position to obtain repeatable machine operations. The valve adjustments can be made over a wide range to obtain a variety of deceleration profiles to suit the application. The deceleration mechanism is independent of the length of the stroke and the repetition rate.
