PNEUMATIC OPERATION DEVICE

摘要

PROBLEM TO BE SOLVED: To exhibit sufficient air drying function with an air drying chamber left in high pressure and miniaturize the device. SOLUTION: This air desiccant is contained in an air drying chamber 13f connected through to a delivery valve 12g of an air compressor, optionally connected through to an air spring 15 by an air supply valve and to an air passage by an exhaust valve. In this case, the first layer of air desiccant 13m composed of non woven fabric of water absorption fiber and the second layer of air desiccant 13j, aggregate of granular silica gel are placed side by side.
