Claims

[Scope of utility model registration request]

a substrate having an inlet connected to the air compressor and an outlet connected to the main reservoir; a first substrate disposed concentrically on one side of the substrate and forming an inner space and an outer space surrounding the same; and a second cylindrical body, and first and second passages within the substrate that guide the inlet and the outlet to one side of the substrate, one communicating with the inner space and the other communicating with the outer space, respectively. A desiccant contained in a space communicating with the entrance side of the inner and outer rain spaces, and a passage located downstream of the desiccant and communicating the inner space and the outer space. a check valve disposed in the passage, which allows air to move from the space containing the desiccant to the space serving as a purge reservoir, but prevents the opposite movement; and a small passage connecting both sides of the check valve. , a compressed air comprising a passage provided in the substrate and capable of communicating the upstream side of the space containing the desiccant to the outside air, and a drain valve provided in the passage to open and close the passage in response to a signal from the outside. In the drying device, the substrate is provided with a bypass passage that connects the upstream side of the desiccant located on the inlet side and the downstream side of the desiccant located on the exit side, and in the middle of the bypass passage, there is provided a bypass passage that is normally closed. A compressed air drying device comprising a valve device that compares the pressures on the upstream side and the downstream side of the desiccant and opens when a pressure difference of a predetermined value or more occurs.
