Claims

[Scope of utility model registration request]

a main body having an inlet passageway connected to an air compressor and an outlet passageway connected to the inlet passageway and an air storage tank; an internal cavity formed inside the main body in communication with the inlet passageway and the outlet passageway; A reproducible adsorbent stored in a space, an exhaust passage connecting the inlet side of the adsorbent to the outside air, and a discharge valve provided in the exhaust passage that is normally closed and opened in response to an external command. In the compressed air drying device having a valve, the discharge valve includes a stepped hole in which a small diameter hole side is connected to an opening of the exhaust passage to outside air;
a stepped piston that is movably inserted into the stepped hole and biased toward the opening side by a spring with a predetermined preload, and a stepped portion of the stepped hole and a stepped portion of the stepped piston; a control chamber formed and supplied with command pressure from the outside; a valve body portion formed at the end of a small diameter portion of the stepped piston protruding into the opening; and a valve body portion closely attached to the opening and having a hole in the center. A compressed air drying device comprising: a lid member; and a valve seat formed around an inner open end of a hole in the lid member and against which the valve body portion can closely abut.
