Part 1 of this series, covering hydraulic cylinders, is in Design Data Sheet 28. The purpose of the present issue is to suggest circuit arrangements which will minimize the tendency of an air cylinder to "chatter" or move erratically when operated at a slow rate of travel. Air cylinders are essentially power, not feed, devices.

Breather filters are placed on hydraulic reservoirs to prevent atmospheric contamination from entering. Air enters the reservoir whenever the fluid level drops. This occurs during normal cycling of the machine, and when fluid cools down during idle periods. Breathers are designed to stop particles larger than 3 µm from entering the system.

The most common use for accumulators is to supplement pump flow. Some hydraulic circuits need highvolume flow, but only for a short periods, and then use little or no fluid for an extended period. When half or more of the machine cycle does not use pump flow, designers usually install an accumulator circuit.
