A pressure reducing apparatus includes a body being equipped with a first side port through which a pressure fluid is supplied and a second side port through which the pressure fluid having been reduced in pressure is discharged. Further, a feedback passage is formed, which establishes communication between the second side port and a third diaphragm chamber that faces toward a pilot valve. Additionally, a pressure fluid that flows through the second side port is introduced through the feedback passage into the third diaphragm chamber, whereby a third diaphragm is pressed upwardly against an elastic force of a second spring into equilibrium. |
