Claims

[Scope of utility model registration request]

In an automatic drain valve attached to the bottom of the air reservoir that automatically drains drain water to the outside, the magnitude of the air pressure introduced into each of the two chambers from the air reservoir is controlled by a membrane plate that partitions the differential pressure chamber into two adjacent chambers. A drain valve that opens and closes depending on the relationship, a restriction inserted into either one of the channels that introduces air pressure from an air reservoir into each of the above two chambers, and the pressure of the air reservoir inserted in parallel with the restriction is the regulating valve pressure. A differential pressure type automatic drain valve characterized by comprising a pressure regulating valve that closes when the pressure rises to a certain level.
