<p>PURPOSE:To eliminate the need to introduce an air pressure signal for opening a regeneration valve through a piping from outside, and thereby simplify the piping compared with the conventional pipe arrangement. CONSTITUTION:A compressed air drying device comprising an inlet 31 in communication therewith, an outlet 33 in communication with an air storage tank, a regenerable adsorbing agent 14 provided between the inlet and the outlet and a regenerating valve 60 provided in a passage for connecting the inlet side of the adsorbing agent with outside air is characterized by the provision of a movable body 50 adapted to open the regenerating valve 60 when the outlet pressure of the drying device reaches a predetermined value upon receipt of the inlet pressure thereof.</p> |
