ことを特徴とする真空圧供給器。 By partitioning two mutually independent chambers with a diaphragm made of an elastic material, the first chamber is adjacent to the second chamber via the diaphragm, and the third chamber is adjacent to the first chamber via the diaphragm. The first chamber has a pressure regulating hole communicating with a vacuum supply source, an opening opening to a target space whose pressure is to be regulated to a target vacuum pressure, and a first chamber and a second chamber. The second chamber includes a valve body fixed at one end to the partitioning diaphragm and facing the pressure regulating hole so as to adjust the opening degree of the pressure regulating hole by displacement of the diaphragm.
It has an air introduction hole that communicates with the vacuum supply source through a small hole and also communicates with a third chamber, and the third chamber is connected to the air introduction hole by displacement of a diaphragm separating the third chamber and the fourth chamber. a pilot valve for adjusting the flow rate of air from the third chamber to the second chamber by passing through the air introduction hole; and an opening communicating with either the atmosphere or the first chamber; A vacuum pressure supply device characterized in that the chamber is provided with means for supporting a diaphragm communicating with a vacuum supply source and forming a boundary with a third chamber by elastic force.
