Abstract

A gas control device () includes a first pump (), a second pump (), a first check valve (), a second check valve (), and a receptacle (). The volume of the receptacle () changes in accordance with the pressure of air flowing thereinto. The first pump () has an air suction hole () and an air discharge hole (). The second pump () has an air suction hole () and an air discharge hole (). The first pump () is a type of pump having a high discharge flow rate and a low discharge pressure. The second pump () is a type of pump having a low discharge flow rate and a high discharge pressure. The suction hole () of the first pump () communicates with a first ventilation hole (). The suction hole () of the second pump () communicates with a second ventilation hole ().
